I had a problem with baking the mesh in substance painter with these wierd lines

the model contains many object, Each object is unwarped on its own, I do not know if unwraping each object with its own uv is a problem or no

I think uvs are printed over each other in baking stage

Hello @kero32442467ckdc,

 

Thanks for the message and the 3D mesh.

 

It appears that the 3D model has several UV islands overlapping. Make sure they are not touching each others before importing in Substance Painter.

 

Regards,

Thanks for your answer

I have tried to make the uvs not to overlap

But the quality of the mesh is very low is there is a way to increase the quality?

You can increase the resolution of the UV map 2048x2048 or 4096x4096 ...etc  If that is insufficient, then you spread your unwrapped UV islands across several tiles using a UDIM workflow if your modelling and rendering app supports it. Don't have a single island crossing the border of UV tiles though.
