I thought about Shadow pass, but I'm sure there has to be some way to do that directly in render. Actually, I saw there is a way in C4D lights and Redshift lights, but I didn't find how to do that in Octane.
Thank you!
Hello, there are two approaches:
1.The physically-plausible approach:
It follows the same physical/light laws as in reality: the colored shadow comes from the colored transmissive object.
There is also the "color bleeding" of colored object lit with a strong light - the surface lit by the strong light will be reflected on near surfaces. It is different from "colored shadows" (due to colored refractive properties of an object).
2. The
non-physically-plausible approach:
There are various ways to achieve that, as it has been mentioned in the thread already - either via Octane or in post/compositing.
