Short description of error
Bake result produce checker artifacts if trying to bake pointiness with subdivision surface and selected to active on.
Exact steps for others to reproduce the error
I use two meshes, one is high poly mesh using subdivision surface modifier and one aren't. I'm trying to bake pointiness of the higher poly to lower poly mesh. I use emission bsdf with pointiness color as input on high poly mesh to render pointiness color only.
I provide the blend file. Just hit bake and see baked result with checker artifacts. It still produce artifacts whether I'm using GPU or CPU render.
