I'm having this problem where the material that assigned into a geometry looked like it's doesn't read in the UV map, I use the same mesh, and it worked properly in SOP level, I got the texture correctly, and I did the same, I brought in the mesh inside SOP create, SOP input and also Component Builder, then copy the same material which I built using Karma Material Builder and assigned it onto the mesh, and the texture got messed up everytime.
It's look like some sort of internal bug from solaris, because I tried assign the same texture onto the same mesh in other programs, it also worked, it just broke in Solaris. And more importantly this only happened on 3 out of 5 assets, I'm not sure what's causing this bug, it's so unpredictable.

Can you send us your assets & hip file?
