Mipmap of block atlas texture inconsistent in deferred pipeline #2501

Open GeForceLegend opened 1 day ago

GeForceLegend commented 1 day ago

What happened?

While using block atlas texture in deferred pipeline, like texture.composite.colortex6 = minecraft:textures/atlas/blocks.png, mipmap level of block atlas texture changes with objects in last draw.

Screenshots

Directly set program output to texture(colortex6, texcoord, 4.0) in composite.fsh (colortex6 has been set to block atlas texture in shaders.properties). Hold a transparent block: Image Hold nothing: Image

This should match Optifine behavior. The last mipmap state will be used for the texture.

Should mipmaps always be on?
