COPS - how to convert SLOPE cop output to RGB ? 2025年9月20日5:25

Thanks loads for that Jeff. It will come in very handy. I need to look into the code more to understand it but I get the gist from your description thankyou.
Techie - although not an exact rendering of the visualizer I really like the look you managed to get out of it. Is it almost doing the same thing as Jeffs code - your projecting the vector onto Hue and using the length for saturation?
Lots to do in the openCL node

COPS - how to convert SLOPE cop output to RGB ? 2025年9月10日12:42

Hello I've been playing with the flow options converting noise patterns to velocity via the Slope sop.
I really like the colours as displayed in the SLOPE SOP and would like to export them as RGB.
The problem I have when doing a UV to RGB is that colours change.
Does anyone know how to conserve the colours?
I thought this was simple but I've ended up doing a deep dive on layer properties and see from inside the sope sop
that its type is 'vector' as a opposed to 'color'. And I'm guessing that its doing something to display it in RGB for us, the U and V set to R and G with some scaling but how is the B ?
Any thoughts much appreciated thanks

I just across this post looking for a solution to miss alignment when bone deforming, captured packed prims in a RBD sim. Mops Align sorts this, but also passing everything through a transform pieces sop. MOPS better
