getting camera transform? SOLVED Aug. 13, 2025, 6:21 a.m.
To simply align orient to the camera:
matrix m = optransform(chs("camera")); @orient = quaternion(matrix3(m));
Procedural Rendertime Point Deform March 24, 2025, 12:20 p.m.
Hi,
We're doing a project where we have a highres curve based piece of knitted clothing, that we need to deform so it follows the animation mesh. We're hoping to find a way to deform the curves at rendertime, rather than caching out tons of geo per frame.
For fur we're able to set up a rendertime procedural in Solaris that will deform the fur to follow the skin at rendertime. Is there something similar for just getting curves to follow a mesh?
I was hoping to misuse the new feather procedural for this, and I sort of can, but it's pretty hacky.
Any tips?

Feather procedural deform example? March 24, 2025, 5:13 a.m.
Hi Kai,
I'm really hoping to get some tips here.
We're doing a project where I want to deform a knitted, curve based sweater so it follows the animated and simmed lowpoly sweather mesh. The full curve based sweather is pretty heavy so instead of caching out sequences I was hoping I could do this at rendertime with a solaris procedural.
Since the feather procedural has some point deform functionality I was hoping it could be used to achieve this also, but so far no luck.
Is there a way to use the feather procedural to deform any curve to follow a deformer mesh? Or is it best to use/ create another procedural for this?
