I'm working on my Capstone Project for my senior year of college. I decided to teach myself Houdini, which is going surpisingly well. Everything is looking good, the only issue I am having is that the collision is slightly off, enough to take away from the realism of the simulation and make compositing way harder than it needs to be.

I'm sure that there is an easy fix. Please let me know if you have ANY suggestions.

I am no expert in this domain, but what I am seeing is particles that are so fast that they travel through the geometry. I don't know how you have set things up, but I would research on Google something related to increasing simulation steps.

Maybe have a look at this thread: https://www.sidefx.com/forum/topic/458/ [sidefx.com]

Edit: One more thing… I think that given your camera angle, it would not be an issue if the collisions happened before they actually hit the geometry. You might be able to apply some generous settings on the collision tolerance side.
