revelationsr Posted March 3, 2016 Share Posted March 3, 2016 I have a sim of particles. These particles are running across the surface of a object. I would like these particles to add a number to a point attribute when they get close enough to that point. Also I would like this number that is added depend on the particles speed. Faster particles add higher numbers added. The idea is to have "water" run over a surface and then "erode" the surface over time. So faster water would move more "sand" Any idea? Also does this make scene? Cheers Quote Link to comment Share on other sites More sharing options...

revelationsr Posted March 4, 2016 Author Share Posted March 4, 2016 O shit son. You nailed it!. Now I need some time to pull what you did apart and figure out how it works. If you could please let me know that would be awesome. I quick side question. Is there a way to take the information of the offset and save it out as a texture. The idea is that when more "water" bunch up in a area then that area will be more "fertile". Alowing more trees to spawn. Areas with less "water" will spawn more rocks.
