Thanks for your reply. Great that the tension map updates color per vertex dynamically. Accessing the colorSet1 actually works right off the bat and scattered points/fibres inherit it once the attribute is setup in the yeti graph.
To follow up on your question, I also like to understand better the underlying data schemes and flows. Admittedly, I need to learn more about mayas mesh objects, complex and multi data etc. Any soup specific points of reference here?
One example, I didnt manage to plug any soup node outputs (arrayToPointColor, etc) into the colorPerVertex node, eg to transfer tension colors to a duplicate mesh... Still lost there.
