Hi!

I'm trying to build a brick wall with very funky shapes. I was thinking of using an RBD sim to stack them together but I'd want it to be 2D (X and Y). The reason is for stability (nothing falls infront of the wall) and to lock the X and Y rotations. ...and faster calculations, maybe?

...Is that possible?

... I found a page that talks about it (in japanese?) but it looks to complicated for the time I have...

A very quick and dirty way to achieve this, no Japanese required.

Drop a solver sop "inside" your RBD Bullet Solver connected to either pre or post solve, didn't notice
much difference in this case tbh, then add an attribute wrangle inside the solver.

v@v.z = 0; will resist/stop Z axis velocity movement

v@w.z = 0; same thing for rotation

I created an example years ago...
