I try to bake a .OBJ sculpt on a .FBX low poly before start the textures and i tried all i know but impossible to succes the bake.
My sculpt is rlly high poly so i separate it in several parts, and do exactly the same on my low poly.
Each time i try to bake a part, substance take its time, it's ok but it give me empty map or map with nothing on it.
Here : thickness, diffuse (it's ok here i didnt put color for now), curvature and normal maps
I checked all files, and all high poly and in correct position on the low poly. I tried to import again both high and low poly files, to reduce resulution, to reduce weight of file by separate again some parts.
I had some error some time like "mesh normals are invalid", "unexpected illumination model" or the last one this morning : "no object detected to attach a new mesh instance". Some time Substance tell me that the bake failed but even when it didnt failed, i'd the same problem of empty maps.
I tried to bake a differents old work of mine with exactly the same method for see if it's work and it's work well.
i try to take just 1 object for test the bake again
low poly smooth for bake
high poly from zbrush
after the bake
so nothing change, lets check the maps :
I really dont understand where the problem comes from and how fix it.
