cgcris Posted January 11, 2015 Share Posted January 11, 2015 Hi guys, Attempting to do something with particles in H13, but I am struggling a bit with the logic of streams. In the attached example you will see I create a second stream, and change the color of a percentage of particles. What doesn't make a lot of sense to me is if I now then add a force to stream 01, it affects both streams. Even if I specify on the force to only affect stream 01. Can somebody explain me why this is? Thanks, Cris pop_logic.hipnc Quote Link to comment Share on other sites More sharing options...
iamyog Posted January 15, 2015 Share Posted January 15, 2015 Not sure about your question. Looking at your file you are applying a popforce to stream_grid_object1_source, which contains all of your particles (middle click and compare the number of points to the number in that group) If you only want to affect popstream1 (the stream you separated), you need to change the popforce position after the merge, or on the 2nd branch and choose the correct group. There is a simple example file you can load from the popstream Houdini help that separates streams based on position, colour them, and apply different forces.
