Rendering effect error #459

Open gladiator-hy opened 1 week ago

gladiator-hy commented 1 week ago

image image I have discovered an issue with rendering effect error. There are two parallel planes here, the top one is diffuse material, and the bottom one is conductor material. As shown in the picture, the left part of the upper plane is too bright, but it is diffuse material. I don't know where the problem lies, maybe sample light? Here is the pbrt files. pbrt_RenderingEffectError.zip I'd appreciate any help.
