2 years ago This is semi-expected. It's not quite a bug, but rather a 'feature' of the sharp transparency quality.
The train uses an alpha channel in it's textures, and the chassis has two stacked alpha channels. Blending between these in a single-pass doesn't work well (for somewhat complicated mathematical reasons), which is what sharp does.
Sharp transparency isn't reccomened unless you're really struggling for FPS.

2 years ago Oh ok i understand now why sharp mode behave like that.
Anyway should the option changed to Low, medium and high ? Instead sharp, intermediate and smooth.

2 years ago Descriptively in terms of what it does, sharp is absolutely correct- It's an absolute value from either the front or rear pixel, wheras smooth is blended between the two.

Low isn't quite right, as if we were for example attempting to replicate exactly a BVE2 experience, sharp is specifically what we want there, as that never supported alpha.
TLDR: It's complex :P

2 years ago Yeah, just reading that how blending works make me feel a bit dizzy 😅
Anyway thanks leezer3
