Using user data string to load texture files

Hello.

We assigned string attributes to the primitives that store the texture path and filename. Then we connect a user string data with the attribute name and connect it to the filename port of the texture file. It should work but it's not..

Any ideas?

Thanks!

You're trying with <attr:texture_name> in the filepath?

Humm, I was using the user data node, I'll try with that expression.

Thanks!

That worked as a charm, thank you!

I wonder why the user data node didn't work. It works for every other data type but not on strings, maybe I'm missing something...

Cheers
