Substance painter bakes transparent patch on mesh normal map

[ezgie39325514]

Hello, I've been trying to bake mesh maps on my low poly model but I've come across an issue. Since I'm not using any high poly mesh, I'm baking the mesh maps by using the low poly model itself. However, on some surface, baking creates a transparent patch on the normal map every time I try. I've made the max frontal distance and max rear distance very small numbers like 0.001, and it didn't work. I can't find any issue on the uv map organization either. Any kind of help or suggestion is appreciated!

In case if someone with the same problem sees this post, I solved this problem by using the .obj of the model, instead of .fbx. However I still don't know why it created artifacts on the .fbx file.

Could be possible that the transparent faces of your Low Poly Mesh have a different Material applied. In this case, Substance has two different texture sets and you can only bake/paint on the current selected one.
