Hi there! I am try to get qood UV2 for my asset. It will be in Unity as static so i need second UV for lightmaps. So because asset can be a huge length i cut the curve every N meters and mark seams from group and then use it for the UV Flatten node. And after i vertex split it its generate some additional point and now points not equal to the first sweep and if i transfer UV its all mess. So my question is how i can promote UV to the point in this case? I understand i should equalize point and get same topology but i dont know how.. Could someone helps me?

i'm match topology and eqal points count but uv2 messing down anyway…

so finaly i solve that by myself.. i group seams from uvflatten and transfer it to sweep1 then i do edge cusp and match topology and then promote uv from sweep2 to sweep1 to points…
