Hi wangvnn, thanks for the finding. I'll look into it, this week probably.

atteneder commented 4 years ago

Do you happen to use linear color space in your project? Because I use gamma space in my test project and it seems be correct here.

Otherwise, please provide your specs (Unity version, platform, project's color space) and sample files and explain what you'd expect (also visually) and where glTFast differs? Did you test Jpeg/PNG or KTX2/BasisU textures?

Thanks!

Is fixed in master for PNG/Jpeg textures. KTX2 still has to get fixed.

Fixed in 1.0.1
