Hi everyone. I'm doing snow simulation using grain vellum. On the image below. Black particles(object) activate white ones(ground) using “popawaken”. Once ground particles being activated, some of them are exploding for some reasons. I did a test when I activated all particles at once and it works well. I tried to increase substeps, collision passes etc. Nothing solved the problem. My guess was that perhaps when black particle is activating white ones, they are inside the radius of the white particle and it cause penetration and explosion, but activation radius set to a high value so particles are being activated way in advance. Seems like with less particle separation value it's more stable.
Does anyone know what might be the cause of this issue ?
Thank you.
