Problem exporting blender model to substance painter, Marmoset and sketchfab When i export this model in as an .obj and import them into the other software the meshes get all mest up. I recalculated the normals and made sure is facing out but nothing fixes it. Also i used other models i had to test and they all work fine so i don't know why this model in specific is giving me problems.


Weird thing is when i flip the normals (they look darker) and import it into SP it looks fine. So i guess the reason i'm having the problem might be the normals but i don't know. also in sketchfab the model becomes transparent.
It seems it was the mesh itself, there were some vertices that weren't connected, making the mesh act like that when exported to other software. So went back took a good look and connected some vertices and cleaned the mesh, that fixed the problem.
