Best way to learn VEX ? Dec. 14, 2018, 12:48 p.m.

High level languages like Python would only hide the explicit programing you need in vex. If any background knowledge would be recommended I'd go for vector algebra as that's typically the domain of a Houdini problem and helps one describe the problem.

Rotate point normals 45 degrees on curve Dec. 12, 2018, 8:59 a.m.

You provably want N as from the vector that is perpendicular to the curve tangent and the normal to the plane the curve lies on. Resample node has a shortcut to get the tangent vector and you already know the plane normal (the direction the door is facing). In a wrangler you can then write, (for example):
vector up=set(1,0,0);
@N =cross( n@curvedir, up);

Support for Maya sets Nov. 26, 2018, 10:11 a.m.

It was always there - “Output Geometry Groups”. We turn them off at load but I remember asking for it to be off per default as they can cause issues in the scene (nothing in the scene can be named as a selection set, even when it is under a parent node - oh maya…). This broke our python wrappers as there was no way to catch the name collisions.
