Breaking changes
If you override shader chunks dealing with reading StandardMaterial textures / uniforms, for example diffusePS, emissivePS, opacityPS and similar, you need to update them to new format. For details see https://developer.playcanvas.com/user-manual/graphics/shader-chunk-migrations/#engine-v27
