Description
When adding shader support, the vanilla lightmap texture doesn't load right. The params.lightMap coordinates are fine, but the actual lightmap sampler isn't reading right. This makes a shader that uses the lightmap texture at all not look right in Voxy (the LODs are black in overworld, darker than usual in end and nether. I know being able to look vanilla in shaders might not be a priority, but I do hope this can be fixed. Thanks!

Research direction
No file or test entry point is named. Start by locating the shader-support code and tracing how the vanilla lightmap sampler is read, then compare its behavior across the overworld, end, and nether. Done means shaders using the lightmap texture render LODs with the expected brightness in all three dimensions.
