kio0o Posted June 21, 2019 Share Posted June 21, 2019 Hey guys, I am trying to set the Alpha of my particles based on their distance, meaning I would like my particles to disappear if they don't have a certain amount of neighbours beside them. Do you have any suggestions how to do it? I was trying to us Nearest Distance Attribute and Point Cloud Radius Comparison, but unsuccessfully.

MaximumsProductions Posted June 26, 2019 Share Posted June 26, 2019 Hey this is just neighbors based. I'm not exactly sure how I'd go about distance, except by per point, add the sum of all the distance from pts found in its vicinity and store in each and normalize for the whole cloud. I'm not very good at point clouds so I would end up doing something silly like creating all the prims, and measuring those and summing them haha. But if you want based on neighbors beside them. just refit the number of neighbors found and play with that normalized value? Cheers, hope this is a step in the right direction.
