r/Houdini

Hi, I need help with a Tsunami sim. I am a beginner in houdini and i found some tutorials regarding tsunami sim but none of them go for flip sim. They all start with RBD destruction. I need a simple explanation on how to create a big tidal wave and create a flip sim.

Hi, I'm doing clothing tests and I've been struggling for a few days with this wobbly effect the skirt has when it moves upwards. I slowed down the video a bit to make it clearer. I've tried increasing substeps, constraint iterations, collision passes, etc. But it's still happening. The scale is high; I tried lowering it to 1:1, but the solver isn't working properly. It needs to be so dense because I want to see the detail of the wrinkles and such. Any suggestions would be helpful for further testing.
