KineFX, Twist Control for fullbodyIK Dec. 4, 2020, 5:41 a.m.

I just tried a toy test adding an ikchains sop after the full body ik solve and I do seem to be able to add additional twisting afterwards using that method. Just delete the tip point from the full body with a delete joints and use that as the goal and create your own twist point to feed into the ikchains sop.
Maybe there's an easier way….

Would it be possible to layer the twist on top after the full ik solve?

IOR vs Reflectivity ? Transparency vs Opacity? March 3, 2020, 9:08 a.m.

Opacity and transparency are two unrelated concepts. Opacity makes an object allow rays to pass through it, and the degree of opacity determines the proportion being blended. Transparency is really transmission, it enables refraction which samples objects behind the surface with a ray bend according to the index of refraction. Transparency=raytracing, Opacity=compositing.

So if you want to composite something Transparent is there are “correct” way to set the alpha channel?
I guess want you need to know is if a ray hot something in the scene or not. Is that available as an export?
