Hello,

I got this error “model contain non-manifold edges” when importing obj that has been zremeshed or dynameshed in ZBrush. Closing holes in ZBrush has no effect.

What can I do to solve this issue ?

Thank you!

Google what mean “Non-manifold” 

Fix it in Zbrush.

Hello dear user,

Please use our Clean model tool in the Reconstruction tab to fix such issues, it is a topological problem which could cause more issues further on.

Thank you but I will lost the UV if I clean the model in RC.

I am not sure how to fix this non-manifold edges in ZBrush, so I may need another tool.

Try it in zbrush

Thank you but this screw up my model. Doesn’t work well for me.

Well 364727060920 cleaning non manifolds in the mesh will always ruin your Unwrap and you will have to make a new one, although you can do it fast in RealityCapture again and reproject the texture to the new clean model.

RC is not very good for UV, that’s why I do them in ZBrush. And RC also makes triangles, ZBrush make quads.

Well then it is up to you and I believe you will have to clean the topology defects out of RC then.
