- Add reflection probes for each test sphere, which can be toggled using
a new dropdown with 3 options (no reflection probe, reflection only,
reflection + ambient). The cull and reflection masks are configured
on each reflection probe so that spheres don't self-reflect, but other
spheres still appear in each sphere's reflections. Probe extents are made
very large to prevent any visible fading, and the test beds don't
receive the reflection probe's ambient or reflection.
- Improve ice material visuals by giving it some opacity.
- Use lossless compression on all textures, as their relatively low
resolution and count by today's standards makes them not use much VRAM
anyway.
All demos were opened with Godot 4.2.1, with the mesh format
upgraded for 3D demos.
The 3D antialiasing demo now uses Extra Cull Margin on the last
object to prevent it from disappearing too early when the camera
rotates (due to its use of shader-based animation).
