Hi, someone can help me to map a texture on a trunk?
I could cut and open manually the uv, but I'll go to lose the procedurality of my work.

I think that the problem is the same, but I can't find a solution. I have to extrude the face of the group along the z axis, but they have an attribute that controls how much is this extrusion (attribute: width).
To do that I have to write a line of VEX code in the node of VEX? Is there a esier way?

That's the Group Create SOP. The “Base Group” parameter acts like Group fields on other SOPs, so expressions of that sort won't work there. However, if you use the new Group Expression SOP, set to group primitives, you should be able to write (@primnum%5)==1for the VEX expression. Hopefully that's what you were looking for.

Ok thank you. Now it's working! I was watching a tutorial that use houdini 14 and he put directly the vex expression in the group node.. Anyway now I get it.
Thank you!
