Hi everyone,

I created this floor to simulate things being thrown on it but I struggled to make houdini understand the negative shape of it as part of the RBD and treat it as a floor including the negative. Right now, when I bring this mesh from Rhino to Houdini, it just treats it as a flat plan and doesnt consider the negative. (Sadly the project is confidential and I cant share the houdini file).

Any help will be appreciated. Am a beginner at Houdini that just started using it 3 months ago.

Which RBD solver are you using?

you can use heightfields as colliders with bullet, so project your shape onto a heightfield and use Terrain Object SOP, check Use Heightfield

I gave it a go but with my minimum knowledge in houdini, it didnt turn out successful. I might just try to remodel the floor in Houdini to make things easier for me and plug it into the Bullet Solver
