Hi Guys,

Thanks to you, I get the feature functionnal.

@ Tamte : Your method is perfectly working. I know get a better vision of the way Houd works

@Joker : My problem was about pushing consistante UV on Primitives. Have a look to the Att. Houdini file for more detail.

Included, my scene.

Big up guys !

Hi all,

First of all, sorry this question is probably hubber newbee centric…My Houdini knowledge is pretty low ops:

So, relatively to “Hoses & Pipes” tutorial, I would like to access primitives length (after the Carve op that breaks the main Curve in Primitives) to create a size relative uv mapping for the pipes (each pipe primitive will receive a correct UV param. depending of its own length)

Right now I succeed in getting the overall curve size and push an expression on UV mapping node, but no success in trying to get each primitives length.

My though are going to :
- It should be nice if Houdini can parse the primitive array for me, and apply the right UV length by primitive
- It will be nice if I can do that with a simple expression.
- It's seems easy by coding a loop, but this will probably impact performances a while. And what should be the best way between the various languages available ?

Anyone can help ?
Thanks
