Normal issues in Marmoset tool bag

tuananhrobert

Hello,

I am having an issue on my mesh where some of the faces on my mesh have problems (black surface). I used 3ds max for modeling and substance for baking. The bake in Substance, however, didn't have this issue. I also tried to use smoothing groups in Max but it didn't change the outcome.

Any suggestions would be appreciated a lot. 

Thank you.

This is just caused by a mismatch in the way your 3d software triangulates vs how Marmoset triangulates the mesh. You can export your mesh triangulated to fix this issue.

I tried to export it triangulated but it still has the same outcome.

Try flipping the triangulation in where the errors are occurring.

I tried to make that area triangulated but no use.
Here how's the wireframe looks like

^Show it in edit mesh mode with edges visible, select edges option select entire chest, edit , click visible makes all the lines come up, looks like a normal issue.
Try .fbx <- import to zbrush, might work if not select object, change the tangent space to xnormal, if doesn't help, its all i got.

Depending on where you've baked the normal map, you may need to export your mesh with triangles and rebake. Then, make sure you're using the same triangulation in each app. If you export quads or ngons you're relying on each app/game engine to interpret that differently.
