hey guys,
i get the error " the mesh contains 2 out-of-bounds UV coordinates " when im trying to turn on dynamic subdivision.
my mesh is a very simple cylinder with some polygroups that i created with the slice curve brush.
my questions are how can i fix this issue and how can i see which UV coordinates are causing the problem. i searched on google but i cant find any info on this problem message.
thx for your time
