Description
Redstone dust appears to have an invisible reflective surface covering its transparent area.
Instead of rendering only the visible pixels of the texture, the entire quad seems to participate in ray tracing, causing reflections on pixels that should be fully transparent.
Expected Behavior
Only the visible redstone dust pixels should be rendered.
The transparent parts of the texture should not contribute to reflections or ray tracing.
Actual Behavior
The transparent area of the redstone dust texture behaves like a thin reflective film.
This is especially noticeable under strong lighting, where the invisible quad reflects light despite being fully transparent.

Environment
- Minecraft version:26.2
- Caustica version:0.1.0
- GPU:RTX 4060
- GPU Driver:GeForce Game Ready 596.36
- Operating System: Windows 11 25H2
Additional Notes
This looks like an alpha masking / cutout issue in the ray tracing pipeline.
It seems the transparent pixels of the redstone dust texture are still included in the ray tracing geometry (or treated as a translucent surface), causing the entire quad to reflect light.
