Speaking of compression, X-Plane doesn’t compress all textures…even if “texture compression” is on, we leave uncompressed certain textures that are flagged. A rough list:
- Most textures in the sky, like clouds and color stripes, have a lot of alpha and get wrecked by compression. They get exempted.
- Anything related to the 2-d panel, maps, and the UI get exempted.
- Some of the overlays like rain and snow, smoke puffs, and lights.
- Taxiway signs get exempted…S3TC does a number on letters and numbers.
