Hello,
i intend to use this tread to learn trough a project.
I need to understand the following:
1. Geometry.
How does one models the liquid in the glass liquid scenario? I know i have to separate the liquid from the glass, and i have them both enclosed, normals facing outward, with a small 1 um gap between the top surfaces. Is this how to do it?
2. Is absorption working correctly ?
3. What are the correct rendering setting to be used for this scenario?
4. What are the correct rendering setting to be used for this scenario in order to have caustics?
i attached 3 renderings. the floor is the same glass as the other glass objects, and there's a background in the back with a hdr emission. Maybe s just me, but i don's think i see any caustics there. I'm rendering right now with PT+PT, but still, no caustics.
