I am a beginner to Houdini and working with Vellum to create stacks of money falling onto each other. I am having trouble with the stack once it lands on the ground plane. It seems to squish together until it is completely flat, as if there is no thickness to each plane at all.
I have changed the thickness and mass in vellum constraints to a higher number, and also tried to extrude my grid meshes but that does not seem to change anything either. I've made the bend/stretch stiffness to a higher number and again saw no changes.
What is the correct way to make my vellum cloth pieces thicker so that when they interact with each other they don't become totally flat and instead layer correctly? I will attach my Houdini project as well as a video of
I dont see the hip file, but from the video it seems like they are really thick as far as simulation is concerned (pscale)
Your issue may be that the @pscale is much thicker than the separation of the papers causing the collision radii to start interpeneteated and therefore temporarily disabled
Make sure the @pscale is not larger than half of the gap between your papers
And definitely keep them as single side grids without any extrusion If you want to enforce the stack shape for some of the bottom or all layers you can add Glue constraints between the layers, but its still important to have valid collisions first
Thank you so much for the advice, I adjusted my pscale but I am still running into the same issue. My thickness is set to 0.015 currently, but I'll work on the glue setting and see if that changes anything as well.
I also attached my hip file in the edited post, if you are able to look at my file. Thank you!
