For rendering section, we can use Substance Painter IRAE render engine and even we can

use another render engine like Marmoset Toolbag, Unreal Engine in 3ds Max, Corona and V-Ray

in Blender, Eevee and Cycles.

It depends on your purpose and your knowledge.

But in here, in this course, we are going to use Marmoset Toolbag as a main render engine.

But let's render this part inside Substance Painter with IRAE.

It's so simple and we can see what's happening if we render the material.

So let's go to the render mode.

You can see this is the icon that we can use for switching to the render mode.

And in the render mode, we have render setting, we can pause IRAE rendering.

We compress knowledge for you!

And you can control.

the time and the quality of the render with two factors. The factor number one is maximum time.

For example, this is a scenario, you have just 10 seconds and you need a render. So you can put

maximum time to 10 seconds or you can change it to minutes or hours. And after that, it's going to

stop if reach that time. But there is another condition for rendering which is samples. So

if you render, for example, for 10 seconds and you didn't reach 1000 samples, the render

it's going to be stopped. But if you reach 1000 samples before 10 seconds, the render

it's going to be stopped too. And if you have noise

on the material after rendering, you need to increase the samples for rendering. And you can

increase time to reach maximum sample or you can just increase maximum sample and take more time.

Okay, this is very easy render engine setup. You have two factors, just two factors. Okay,

so we can override the viewport resolution. As you can see, for example, I'm going to post this

render in Instagram. So maybe it's good to have a square aspect ratio, as you can see.

But we cannot see the camera border.

Because the render engine is paused and when we resume, we can see what we have here.

Okay, so this is so similar to a 3D viewport.

You can rotate, zoom, or pan the camera.

Okay, like this.

And after finishing the render, you can save your render in here.

With any format that you want and any name that you want too.

What else we have inside the rendering in iRay inside Substance Painter?

So we can go to the shader setting and enable something like displacement,

something like opacity, or translucency for creating glass, or something like that.

You can create...

emissive material and control the emissive intensity in here, or anything else.

But the main setting that you can do inside the render engine, it's on the display setting.

So you can change the environment map.

Okay, so the lighting condition, the background is going to be changed.

You can change the setting related to the doom, and you don't have doom option when you are in the viewport, and it's totally new.

So, you can check the clear color, and after, you can see there is no sign of background.

Okay, you can check the ground, and have a shadow, like this.

Like this.

You can even turn off the ground and don't have a shadow or reflective.

Okay, so let's go back and use HDR.

I'm going to bring up the plane near to the surface, like this.

And boom, we have this.

Okay, and you have access to camera setting with display setting, and change focal length, like this.

Okay, and you can activate the post effect. The post effect is like creating lens distortion.

Change the FOV.

edge around this and create this kind of image. You can add vignette to the render like this.

You can create glare and play with the parameter

like this.

You can use Tune Mapping option like Exposure or Gamma as you can see, but please don't touch

to Function and change it from Linear to something else because we have aces here.

And we didn't even use Tune Mapping in the Substance Painter

Render Engine because we have Photoshop or other photo editing software and we can do

this kind of stuff over there with more option and feature.

So turn off the Tune Mapping and you can use Color Correction. For example, you want to increase the

saturation of the render, you can do that. You can control the contrast of the image

that you are going to render and you can control the brightness

or white balance.

But I strongly suggest you to keep this kind of editing for post-process in the other software

like Photoshop or any other photo editing app. Okay, the most important thing is DOF

or Depth of Field because we can have it inside the render. If I check DOF you can see

we can set Focus Distance and Aperture and you can control

this setting.

Okay, and that's it.

Let's decrease the aperture.

And we have a clear DOF inside Substance Painter.

We're just changing parameter from aperture and focused instance.

So, this is how we render inside Substance Painter.

And we don't use Substance Painter as a render engine at all,

because IRAE, it's a good render engine, but it's so expensive.

And it's not, it's not rich in the feature.

For example, if you use MarbleSort Toolbag,

you can do many things like animation, exporting model,

exporting MarbleSort Viewer and use it in our test station

as a web browsing 3D model.

But with IRAE you can just render an image with so many limitations. For example you cannot

add any additional light and it's a beginning for the issue when you want to render in the IRAE.

But we need to discuss about that and this is your choice to render with the IRAE or use

Marmoset Toolbag as a main render engine for the Substance Painter result.

So let's go for the next video. We are going to export the texture from Substance Painter for this

project and move it to Marmoset Toolbag and we are going to warm up with Marmoset and learn

the Marmoset workflow and how it works and use it in the future for all projects that we have.
