Conversation
Untinted image() draws and textured PBR draws took the opaque material path, and Bevy forces alpha to 1 for AlphaMode::Opaque. Any PNG with transparency rendered with a solid background, and translucent textures on 3D shapes were opaque.
Image tracks whether it has translucent pixels. The flag is computed on create/load, recomputed by update_pixels/update_raw, set by set(), inherited by copy_from, and assumed true for render targets since their alpha is unknown
until read back.image() uses the flag to pick the transparent color material; texture() does the same for the PBR material. Opaque images keep the opaque path.- Offscreen
Graphics now start cleared to transparent, like Processing's createGraphics, instead of gray.
- Python:
image(pg) accepts an offscreen Graphics directly. It previously raised expected an Image or Webcam.
