Hi,
I have a problem on a postprocessing made with WebGLRenderTarget.
If i use a rectAreaLight and a mesh with a MeshPhysicalMaterial (or MeshStandardMaterial), when I render scene by simple postprocessing this mesh won’t render, but if I render without postFX the mesh will render.
In this SanBox you can see the bug:
row 129 you can disable the postprocessing render and you will see that the mesh isn’t rendered.
The mesh is black so it seems you are not using RectAreaLight correctly. It’s mandatory to call RectAreaLightUniformsLib.init(); if you want to include this type of light into your scene. This is also done in the official example:
