Title: Rayswitch material and Material Override
Post by: Adam on 2024-05-27, 08:49:18

I have used a rayswitch material to create a water material that can generate caustics via a bump map and not have the bump map show on the surface of the water.
Basically set up as follows.

GI: has a water material with a bump map for caustics
Reflection: water material with no bump map
Refraction: water material with no bump map
Directly visible: water material with no bump map

If you render the scene normally everything works fine, water has a flat surface with no bump visible but if one is using Material override, excluding the water object, and have preserve bump selected the bump map from the GI slot becomes visible, which isn't ideal. Is this a bug or a limitation of the Rayswitch Material and Material overide?

Interesting, we will try to reproduce it ASAP.

Meanwhile, could you try a setup with a rayswitch map instead? (attached)

This is now reported for the dev team. The workaround which I mentioned in my previous post should work. The problem seems to appear only if the bump material is nested inside the Rayswitch Material.
