in this tutorial series I'm going to cover

how to use redshift with Maya

and in this video

I'm going to start with a basic overview

a crash course

on using the ratchet render

if you don't know

a ratchet render is a GPU based render

which is very fast

and I've been using it for the last few months

and I really like it

I like the results and how fast it is

and in this I'm going to tutorial a series

we're going to cover everything you need to know

to get started

and to begin rendering with it

so in this video let's get started with the overview

and how to begin rendering your first

few frames so after you've installed redshift

and then you launch Maya

you should see a new dropdown menu

on the ratcheft

and you should also have a tab ratcheft tab right here

if you do not see either one of these

then you may need to enable

in the plugins to make sure it's loaded and are loaded

so if you go to Windows

setting the preferences and then go to Plugin manager

make sure that right here red shift formiya

it is loaded and auto loaded

and if you don't see this you may need to search for it

so you just step in red shift

and it should pop up

and then once you've done this

you should have a tab up here and a dropdop menu

and you should be ready to go

now I do not use the dropdop menu

I really don't remember the last time

actually used for anything

used in redshift

and everything I need

is right here in

the custom tool shelf that comes pre installed

with ratchet and everything I need is right here

so the first few icons

these first four are your render view

your render current frame your IPR

which stands for Interactive Photorealistic Rendering

this is kind of like real time

where you can adjust properties materials

lights and it will update

at the same time

in real time and then you have your render settings

now these icons right here are going to be very similar

to if you rendered things in Maya before

you'll also have access to these same icons right here

and you can actually use the Maya version

and it will work with redshift

by Graph Shift comes with its own set of menus

the render view looks a little bit different

so let's go ahead and just

left click on the render view

and let me bring it into the view

and this is what the render view looks like

so I like using the render shift render view more

than I do the render

view from Maya

but you could use

the Maya native one and just render with red shift

so if I go ahead and just show you what it looks like

you can actually use this window as well

so if you used to this

you may stick with this but I really like

what comes with redshift

the only thing here is if you do

end up using the renderview

from Maya

you just have to make sure that you switch your render

to the redshift and then you render with it

so if I open up the renderview again

this is your primary window to see

what you are rendering

and you have a few icons here

it's a lot cleaner than the Maya render view version

so this is what I use now

the second one is it's going to render your

current frame

so if you just left click on the second icon

it will render whatever I'm looking at now

I don't have anything in the scene

so it'll be completely empty

the IPR is the interactive photorealistic render

basically

it will update any changes you make inside the scene

and I'll have to show you when I actually have some

lights or maybe some materials

it will also update your camera

and then the last icon the fourth icon

is your render settings

if you open that up

you have a bunch of settings here you can change

to improve quality

and I mean there is a ton of settings here

and a lot of these we are not going to cover

but a few here are very useful

and they'll go through them

so I'm going to go ahead and close this for now

now we can't

see anything inside because we don't have any lights

we don't have any objects inside the scene

so let's go ahead insert something to work with

so I'm going to zoom in and let's create a cube

I'm going to make it larger

place on the top of the grid

and also I'm going to create a flat plane

usually when you render things you have to have

some kind of a

ground plane so you can have cast shadows

so I don't want this

cube to it floating in an empty black space

so let's go ahead and create

a plane and make that larger

and I'm just gonna

change the subdivision axis to 1

so it's just easier on ice

and let's go ahead and do our first render

so I'm going to come over back to the renderview tab

and click on renderview print this up

and I usually don't click the second icon

I usually open up the renderview

and in order to render your current frame

all you need to do is click on the spare you left icon

right here render

it can render from your perspective point of view

and show you what you are looking at

because we don't have any lights

it's going to use the Maya

default lights

so it's going to give you this flat shading

so in order for us to start rendering and seeing

some good results

or any results

we need to insert and use some wretch of lights

so I'm not going to cover lighting in this video

that's going to be in another video

and I'm going to split those up in a few sections

but because we're going

to cover the interface and the render view options

we need something

we don't want to just look at this

and go through the option

so let's go ahead and insert a light

any light will do

just so we can have something to look at

again I'll cover some of these little later

but to insert a red shift light

you have 1 2 3 these five icons right here

these are your red shift lights

I recommend that you do not

use any Maya lights and use only retroflights

so as you know you can go to create

lights and you can use these right here

but these are Maya based lights

and when you use an ounce I render like redshift

comes with its own

redshift lights

and you'll find them right here

so right here the first one I'm gonna right click

anytime you see a little triangle on the corner

that usually means there are

additional items underneath this menu

so to get access to this

just simply right click or give you a drop down menu

and then you can select very similar lights

if you used my before

you have your 4 basic area lights

point lights while light and directional light

so to have something here

let's go ahead and I'm going to use an area light

and I'm going to go ahead and pull this off

and resize this

don't worry about how I'm doing this

I'll cover this a little later

but I want to just have something inside the scene

and anytime you update

since we're not using IPR

which is interactive version of rendering

which happens everything in real time

anytime you add a light or anything like that

anytime you change the material

you'll just have to do another frame render

so just when I left click on this again

and just take a look what's happening

so here we have a basic scene

with a simple light

and then anytime you update anything

you just click and run through that single frame

now because the slide is very intense

the intensity is too high

because the scale that I'm just going to move it back

just so it's not as intense

and creates those spotlights so that very harsh

light of an effect

so here we are we did a very basic frame render

using one of the lights

and we didn't really change any properties

but we just wanted to get something going

so when you have your red shift render view open

the way you navigate inside here

in order to zoom in and zoom out

you can hold down Alt

and then right click

hold and drag in order to

zoom in and zoom out on an image

and if you hold down Alt and middle

mouse click and drag

this will pan the image around

and if you want to frame it hit F

and this will frame your view

so all this does is simply navigates

I zooms you in and out and moves damage

and one thing you'll notice that I want to point out

is we are rendering from a perspective point of view

if we had cameras in here

we could render from a specific camera

and I'll show you how to do that a little later

by just to point out this is where you'll

get access to any

additional cameras you're inserted inside the scene

so you can render from them

so anytime you make changes

you just basically have to do

what's known as bucket rendering

you just left click and this will render

your current frame once

now the power of using the ratchet render is using IPR

and it's going to be the second icon right here

as soon as you enable it

this will begin to interactively

update you seen when you make any changes

so if I move the camera

this will move along with it and update

if I take the light

and I change the properties for it

so in this case I'm only going to scale it

because the way area light works is if you scale

it increases or decreases the intensity

by just as a side note

you can adjust many

properties for every light you insert

by going into the attribute editor

with the light selected

and you have a bunch of properties here

that will go over

in another video

right now I'm simply going to just scale it

just to show you

so as long as I have IPR enabled

you can see that I'm scaling the light

it's reducing the intensity

if I move it it's interactively updating the scene

so this is real power of IPR and ratchet fronter

you can see how quickly it updates

you don't really have to wait much

and you get to see the results

now every time you move around and it updates

you will see a small little progressive rendering

little thing that's kind of counting up

and you also see it right here on the bottom left

basically it's constantly updating to go to the final

best quality version

so this is why it's able to render so quick

because even though you moving things around

it's updated

but then it's constantly improving the render

as you work on something else

so sometimes you get a lot of noise

maybe the quality doesn't come through

but then you just have to wait until it finishes

but you don't have to wait

you can just continue making updates

and it does this in the background

now the best real

quality of your render is always going to come through

bucket rendering

so again this is not

the final best version

this is just interactive work in progress version

but then when you do a final render

you should really

just do bucket rendering which is just a single frame

and just re render everything

and this will actually go through

and whatever settings you have if you

change any settings and increase any quality

through the render settings menu

then it can actually update and give you the final

result the one you would actually want to save

and keep and do something with

so these two icons right here

these are your go to for rendering

one is your final

the other one is your work in progress

interactively in real time

the next few

important icons are ability to save you screenshots

so it's going to be very important

that when you're working

you may want to save a work in progress

then you update some lights

maybe change your camera angle

maybe adjust the material

and then you do another render

and you want to compare it before and after

and the way to do that is take a snapshot

a screenshot inside the redshift renderview

to do this if you come over here

I end the menu

and sometimes you may not see these icons

you may have a little dropdown menu

to get access to more

or you might just need to open this up bigger

you will see two icons right here

one will say snapshot

and the other one is take snapshot

so to take a snapshot just left click

and this will take a current snapshot of your

current rendered frame

and it will save it right here on the bottom

then you can maybe let's say you update some lights

let me go ahead turn on an IPR

maybe you update and you say

okay well I want to compare the before and after

maybe I rotated the light

I want to see the before and after

and then you come over here and you can take

another one

and then you'll have the first one

and then you have the second one

and you can cycle between each

or if you can have more you can just go through

and you see the before and after and compare

this is very useful

and let me go ahead and take another one

just so I can show you how to delete one

so let's say I position the light here

and move it back and I'll take another one

so now I have 1 2 and 3

if you ever want to delete a snapshot

just simply select it

and hit delete

and this will remove it

now as this does not save any screenshots

it just skips out of memory

but when you shut down Maya and restart it

these will be gone

so just note that

if you happen to want to actually save your screenshot

you could go to file

save image as

and just save it as let's say

PNG or JPEG

and that way you have your

screenshot rendered and saved

if you don't see this window on the bottom

or maybe you want to just go ahead and hide it

you can go ahead and left click on this icon right here

and this will hide

the snapshot view or you can bring it back

you will also have access to it right here under view

as well as a few other options

we're not going to go through every single one

but let's say you don't see a status bar

you can just enable the status bar

shows up on the bottom

and a few other ones

so if you ever lose some of the menus that

are not there

that's how you bring them back

so a few more things

for this very quick overview crash course is

ability to render from specific cameras

this becomes very important and very important to know

very early on

so rendering from your perspective

viewport is not really done

you want to have a dedicated camera to render from

so that we can navigate around the scene

you can update and then

you could work on your scene and then it won't actually

update in real time

basically you can adjust settings

lights materials move things around

and you see it update from the camera point of view

rather than your perspective

so to do this you need to create a camera

so if you go to create cameras camera

this will create a

camera to look from and to render from

now I'm simply going to take this camera

and I'm going to scale it so I can see it better

and just move it up

and I'm going to look through the camera

in order to just position

and get my angle

this is a very common way

if you worked with cameras before

you know

you first you need to kind of position your shot

I'm next temporarily jump over to my camera

by going to panels

Perspective camera 1

and just adjust it position it where I want it

what I want to render

so let's say this is my angle

and I can even enable the resolution gate

so I can see exactly what's outside my frame

and then I'm going to jump back out

so I can work inside my perspective viewport

right so in order to start rendering

you can use a drop down menu right here

and the camera should show up

if it doesn't sometimes it doesn't show up

just do a quick render

and then use a drop down menu again

and choose the camera that you just inserted

and then once you have selected just do a render

or do you just do our IPR

and it will begin to render from that camera

so now I can move things around

and move and navigate inside my perspective viewport

while

seeing exactly what I'm looking at and what my final

shot is so I can even duplicate objects

say Ctrl d to duplicate maybe I can size it down

you can see it's updating in real time

and I'm seeing exactly for my camera

this is very very useful

and one more thing before we finish up with this

basic overview

and we continue to other videos with more focus

I want to show you how to change your final

render size of your frame

so what I'm looking for

through here has a specific size

so if I go to file save image as and I save it

it will have specific resolution

now the way you set

your resolution of your screenshot to save

is you have to go to the render settings

so go ahead and click on the fourth icon right here

and the way to change that is going to be under

comment tab File Output

actually it's going to be a little further down

it's going to be under resolution

and you have a preset

and here is where you change

the size of your frame that you're going to run from

and because I already have a camera

I may want to switch over to camera 1

in order to render and set my

settings for the camera I'm going to render from

and here I can set maybe let's say I want hd720

so this is where you set the width and the height

and the resolution of your render shot

and you can close

and the next time you render

it's going to render in high resolution

whatever you set

and you can always

check right here on the right hand side on the bottom

it will show you the resolution of your current frame

and then once you're done let's say this is your final

shot then you can go ahead and save your image

and it will save it as with that new resolution

alright then

so this is all I wanted to cover for this very first

overview crash course video

enough to kind of give you an insight

get you started to rendering some basic scenes maybe

rendering from a camera

and just kind of set us up for all the future videos

in the series that I'm going to do

to cover how to render

using redshift in Maya

so I'll see you in the next video
