I’ve been trying to fix this issue for a while now with no luck. Seems like a very basic request from an Archviz perspective, but surely there’s a way to show reflections on a glass window? Does anyone know what I’m missing here? Any help would be hugely appreciated!
I’ve tried the following to fix this:
- “support hardware ray tracing” is turned on in project settings.
- “use hardware ray tracing when available” is turned on in project settings.
- DirectX12 is checked in project settings.
in my post process volume:
- Global Illumination is set to Lumen.
- Reflections are set to Lumen.
- Lumen reflection ray lighting mode is set to “hit lighting for reflections”.
- Ray Tracing Reflections is set to “include transparent objects”.
- Rendering Features > Transparency is set to “ray tracing”
- “infinite bound” is checked.
My glass material has the following properties:
- base colour 0
- specular 1
- roughness 0.05
- opacity 0.1
- IOR 1
- blend mode “translucent”.
- translucency > screen space reflections is unchecked.
- translucency > lighting mode is set to “surface forward shading”.
I’ve tried using planar reflections which are a) super laggy, even just for one window and b) don’t actually seem to show any reflections either! I’ve also tried using Relfections > Method “Standalone Ray Tracing” which just seems to make everything very blue… - please see below for that.
I hope that’s enough information to help find a solution.
Thanks
