UE 4.22 Ray Tracing Glass Material Problem
I'm testing out the new ray tracing feature and I'm wondering what parameter I need to tweak to be able to trace through glass materials.
As you can see in this screenshot, the light does not appear in reflections. The window is one mesh, set up with Material ID's for the frame and glass etc.
For this window though, I separated the frame and the glass and it works well. I'm using the same glass material on both windows, but somehow they behave different. Is this a bug or am I missing something?
