In this post, I will talk about how we can achieve some basic layering and masking in iRay. In my last, shower scene I used this technique to balance colors on female head and also to create water drops on the model.
All I used was “composite” map with iRay. Yes, “Composite” map isn’t officially supported with iRay but it’s supported with “Addition” and “multiply” blending mode as well as we can adjust the opacity. And we can also use “color correction” map inside composite map.
Here is the sample image which I did using composite map to showcase basic layering in iRay.
Here, you can download the max zip file to understand the scene. I hope that helps with layering inside iRay.
Note : I didn’t use “noise” map as mask (in mix map to blend grass and dirt) becoz noise map was giving different pattern when used in displacement maps and in diffuse map slot. In both slot, noise map gave different output. So it’s best to use substance map or bitmap mask.
