Hello Daniel, thank you very much for your answer. The approach you described is really inspirational, thanks for describing it. So far I am also doing most of the layout in sops or obj contexts. I have read a post (before the 20.5) that SideFX is reworking some of the concepts. SO I believe that in the near future we will have better LOP tools.

I found the post:

"The layout LOP has seen some bug fixes since the H20 release, but major improvements to that node will have to wait until the Houdini release after the next one."


Thanks a lot again and best regards!

Please, if anyone has any idea, what might be the steps to reproduce this issue, I would be really thankful.

It might be caused by working with the Animation Editor while cooking. But I am not able to successfully find simple steps to reproduce it.

Please, I would like to code a color toner in VEX, to generate @Cd attribute in SOPs. Similar to the After Effects CC Toner (image attached).

Is this plan correct, as regards mathematics and color theory, please?

1) convert output colors to HSV with rgbtohsv()
2) use spline() to output an interpolated Hue
3) use spline() to output an interpolated Saturation
4) use spline() to output an interpolated Value
5) convert the HSV back to RGB with hsvtorgb() and output that RGB

As regards the spline(), the "monotonecubic" interpolation should be fine?
