Masoud 14 Posted January 28 Hello; For some reason I need to increase "substeps" in a "POP solver", but the problem is it increases the number of generated particles! How can I fix it? Thanks for helping. Particle_Substep.hip Share this post Link to post Share on other sites

As i can see you want particles born just ones, in this case use expression in 'Impulse Activation' parameter: $ST < ch("../timestep") It will be independent how much substeps you have.

Hi Victor and thanks for your reply, I changed the "Impulse Activation" from $F==1 to $FF==1 , and problem solved. Share this post Link to post Share on other sites
