Red lines means Seams created

Use the command Clear Seams to delete it

It does not appear to be doing anything. Even if I delete an old face and recreate it, it is seemingly creating seams that i cant get rid of with clear seams. I just duplicated the layer and it isn't dong it on the duplicated layer. While this technically works I am still really confused why it was doing this to begin with.

I have the same problem now in Coat2022.45

I cannot delete this seams, they appeared randomly. Is it okay to post in an old thread? I think it might be the same problem.

Can only repair it with the new join clusters tool. Good thing.

Some faces of Polygroup26 & Polygroup10 are on UVset Polygroup2.

Polygroup6 is on UVset Polygroup1

Are not unwraped, so are not visible on UV preview



- Select all faces using this command or manually (I unwrapped it before)


- Move to Default


- Delete unused UVsets


Use Joint Clusters to cleanup red lines
