isah_voodoo Posted September 4, 2019 Share Posted September 4, 2019 Hello, I am trying to shoot particles at a red object. When the particles move through the red object, I want the particles to turn red as well. An attribute transfer will not work on its own since the particles will eventually move away from the threshold radius. So I am trying to work with a solver. I think I understand the basic concept of how a solver works, but for some reason, my particles don't move when I hook everything up. I must be missing something here. I was reading up on solver on cg wiki : http://www.tokeru.com/cgwiki/index.php?title=The_solver_sop The example "Transfer pop colour onto geometry" is pretty much what I want but opposite. Instead of the grid inheriting the particles color, I want the opposite (particles inheriting the grid color). When I switch things around inside, I still get the same problem. I am going mad I will attach my scene file for anyone that wants to take a look. Thank you. solver_particles_cd.hipnc Quote Link to comment Share on other sites More sharing options...
Sepu Posted September 4, 2019 Share Posted September 4, 2019 Use pop streams, here is an example. You can use popstream for many different manipulations of your particles. solver_particles_cd_FIX.hipnc Quote Link to comment Share on other sites More sharing options...
isah_voodoo Posted September 5, 2019 Author Share Posted September 5, 2019 @SepuThank you Sepu for the file. Even though I wasn't aware of the pop stream node (which looks to be very useful), I was hoping to find a solution without having to go into a particle network. I wanted to understand the solver a little more . I thought this would be a perfect problem for a solver but from what I understand it is more complicated than it looks. I appreciate the help Quote Link to comment Share on other sites More sharing options...

isah_voodoo Posted September 7, 2019 Author Share Posted September 7, 2019 @vicvvshThank you !. This is a great file to learn from. Still trying to wrap my head around how solvers work. Quote Link to comment Share on other sites More sharing options...
