This is a very quick overview of how to use AOVs in Clarisse.
I started from this very simple scene.
Select your render image and then the 3D layer.
Open the AOV editor and select the components that you need for your compositing. In my case I only need diffuse, reflection and sss.
Click on the plus button to enable them.
Now you can check every single AOV in the image view frame buffer.
Create a new context called "compositing" and inside of it create a new image called "comp_image".
Add a black color layer.
Add an add filter and texture it using a constant color. This will be the entry point for our comp.
Drag and drop the constant color to the material editor.
Drag and drop the image render to the material editor.
If you connect the image render to the the constant color input, you will see the beauty pass. Let's split it into AOVs.
Rename the map to diffuse and select the diffuse channel.
Repeat the process with all the AOVs, you can copy and paste the map node.
Add a few add nodes to merge all the AOVs until you get the beauty pass. This is it, your comp in a real time 3D environment. Whatever you change/add in you scene will be updated automatically.
Lets say that you don't need your comp inside Clarisse. Fine, just select your render image, configure the output and bring the render manager to output your final render.
- Just do the comp in Nuke as usual.
