Hi,

i am dropping a sphere node, a uv texture node with polar and the uv seems are pretty bad at one edge, how can i get perfect uv's on a sphere? Attached is an image

Hey cpb, this only works if you use “vertex” as the attribute class on the “UV Texture” Node. However i am using a ray sop to transfer the UV's to another object, but then of course the uv attributes are promoted automatically to point attributes and the seams are back. Any Ideas?

vertex-split and open torus work, both split the geometry though…

I'm also interested in this method. We want to projected seamlessly on this bass model.

I was thinking polar or cylindrical UV projection would be best. This way textures can keep wrapping around the body portion seamlessly.

I've experimented with UV Flatten but this has a seam. Maybe I'll try UV Pelt again.
