Vector Displacement?? Sept. 28, 2010, 10:17 a.m.
Hi!
This Vector Displacement worked in houdini 10 but it dosen't work in 11. It seams that the problem is in inline code. I'm using text: vop_computeTangents($tanU, $tanV, normalize(N), $uv, 2);
Maybe someone knows how to fix this error. Thanks.

3D Coat to Houdini tutorial Sept. 12, 2010, 5:09 p.m.
I found the reason why 3d-coat PTex dosen't work in houdini. It´s because .obj format. Right now 3d-coat writes it as:
f v1/vt1/vn1 v2/vt2/vn2 v3/vt3/vn3 … (which is correct way but houdini has some problems to understand it when used with Ptex)
if I change it into this:
f v1//vn1 v2//vn2 v3//vn3 … (samples from ptex.us use this way)
It works and I get beatiful Ptextures. It seams that it's more houdini issue than 3d-coat. Hope we can find a solution.
It's not so hard to write a script to change the .obj file but it should not have this kind of issue in the first place. Thanks.
