Hello

I'm new with Houdini and I have some trouble with the uv workflow.
How to make a sweep wtih linear uv?
I try UVTexture Sop but it only works with nurbs profile and when I convert the nurbs surface to polygon the normal are strange… half is flipped (see attached file).
I saw the point normal of grid1 which is my nurbs profile. but i don't know how to correct it.

Thx for your help

I don't really see any normals in your scene because you haven't created them.
As for your facenormals, those are flipped but you can fix that with a reverse SOP. With linear uv do you mean that you want your texture coordinates only go from 0-1 over the lenght of the spline ?

and I have another question with the polybevel sop and the texture coordinate.
I have a box i create some uv mapping (see attached file) and at the end I bevel the box. but the bevel don't update my uv map.

How to make that?

Thanks for you reply
yes I want my texture coordinate “vertical” as they are in the first file ( i didn't scale them but i know how to do that)
that why i have used the UVTexture sop wtih the uniform spline option.
but i'm not confortable with the NURBS. I 'm used to works with polygon.

If I can do the same things with polygon only….
