    • prepareBlockLitSamplers

      public static void prepareBlockLitSamplers(net.minecraft.client.renderer.ShaderInstance shader)
      Primes the shader's sampler map so that ShaderInstance.apply() binds the block atlas to Sampler0 and the dynamic lightmap to Sampler2 for the non-Iris block_lit pipeline. MUST be called before shader.apply().

      Why. ShaderInstance.apply() iterates samplers by JSON array index j, uploads Sampler"j" uniform = j, activates GL_TEXTURE0+j, and binds the texture from samplerMap. If samplerMap.get(name) is null, the entry is skipped — uniform stays at its link-time default of 0, so every sampler reads from GL_TEXTURE0 (the block atlas). That's the root cause of the "everything is solid white" regression: texture(Sampler2, lightmapUV) was reading the atlas at uv ≈ (0.97, 0.97) — a near-white atlas corner — instead of the lightmap.

      Vanilla's VertexBuffer._drawWithShader solves this by calling shader.setSampler("Sampler" + i, RenderSystem.getShaderTexture(i)) for i = 0..11 before apply(). We replicate that here because our render path goes straight through glDrawElements and bypasses VertexBuffer.

      For JSON samplers ["Sampler0", "Sampler2"]:

      • j=0: Sampler0 uniform = 0, atlas bound to GL_TEXTURE0
      • j=1: Sampler2 uniform = 1, lightmap bound to GL_TEXTURE1
      The shader's texture(Sampler2, lightmapUV) then correctly reads GL_TEXTURE1 (the lightmap) via the Sampler2 uniform value of 1. The name "Sampler2" is purely cosmetic — vanilla uses the same convention for rendertype_solid.
