[H16] Unable to get detail value through pointvop Oct. 30, 2017, 9:23 a.m.

Right so, i cant make this work in my file for some reason. I just attached the project. If you go into obj > Wall_base

At the bottom you'll see the atribtue VOP with the exact same setup as i attached earlier but it simply doesnt work. the importdetail node in the VOP returns 0,0,1

EDIT So i think i found the problem, something to do with float precision, turning -3.32609e-08
into 0. Trying to rint(val * 1000) / 1000 still returns 0.

Upon further inspection of the video the Normal array is typed as 3fn but mine is typed as Nml. Perhaps Import Detail can't deal with this?

Im actually following a GaTu tutorial on procedural walls, looking to start incorporation houdini into my studio's pipeline.

There is a video where we've just sweeped a curve and are now trying to cap the geo. This uv projection stuff with the normals is to properly create uv's for the cap no matter rotation.

I'll give these suggestions a try when i get back in the office!

Odd, i'm doing the exact same thing at work (same version of Houdini) and there it doesnt work. I'll update my version.

Ive attached a copy of what i'm trying to do however.
Rotating a UV Projection node to match the orientation of the averaged normals. Not quite right yet. Anyone see what i'm doing wrong?
