Detailed Description

GPU-side layout for PBR material with spherical harmonics Used by MovableDiffuseShader, L0/L1/L2 shaders, and DynamicTextures.

Layout (std430 compatible):

• offset 0: 4x uint (texture indices) = 16 bytes
• offset 16: vec4 baseColorFactor = 16 bytes
• offset 32: vec3 emissiveFactor = 12 bytes (16-byte aligned due to std430 vec3 rules)
• offset 44: 5x float = 20 bytes
• offset 64: 2x uint + 2x uint padding = 16 bytes Total: 80 bytes
