Hi everyone,

I currently working on a simulation where everything is working great except for the floor collider.

The floor has been modeled in Rhino and brought to Houdini as an OBJ but for some reason the Bullet Solver is not reading it correctly.

I was told to process the OBJ floor into > vdbfrompolygons > convertvdb before plugging it into the bulletsolver, but that wouldn't still work for me.

Should I just remodel the floor in Houdini ? and can anyone show me how ?

I'd again suggest reprojecting to heightfield and loading it using Terrain Object DOP
If you have any specific issue post your file

EDIT: or since you are using rbd solver in SOPs you can just set it's Ground Type parameter to heightfield and point it to your heightfield
