POP Collision Detect
- [Voiceover] Alright, so the next node we're gonna add is a pop collision detect. So we'll do a pop collision detect. Alrighty, so we're gonna open that up, and then we are going to go to the SOP Path area, and now let's scroll to the top here, and we're gonna go to the ground object, and you see we have a out particle collision object, which is the one we want. So we're gonna say 'yes', and now we are gonna change the default particle size to .1, cause this is sort of internally how large it thinks that particle is, and the default value is too small. Turn off 'deforming geometry', cause we don't need it to re-evaluate every frame, because the geometry isn't deforming. And now I'll go under 'behavior' and change the response from 'none' to 'slide'. So now let's rewind this, and let's play it back. And now you can see instead of getting our particles, like falling through, as they were before, now we're colliding with this geometry of our little volcano here. And by default you can…
