Hi! I'm working on a personal project where I need to make a medieval type Stone Wall.

I used the uv layout method to place the stones, now I'd like to do a simple rbd sim to de-intersect using the found_overlap trick.



I need the sim to not move on Z Position and Y Rotation. Using @P=0; on a Geometry Wrangle helps but it transforms the stones to the center (It needs to respect the pre-sim Z Position).



Thanks!

Thanks for the reply Honza,

I haven't been able to reproduce your solution, I'm new to rbd and dops sorry

This is the code I tried for the geometry wrangle (connected to postsolve)

vector rest = point(0, "rest", 0);

@P[2] = rest[2];

# no idea on how to restrict the y rotation

As I mention on the start, this is part of a medieval wall. My objective with the rbd part is to give more variety to the uv-layout result and get something like this texture [quixel.com].

This is my progress so far, but a lot of stones still intersect. The stones are all packed primitives.




If you can provide an example it would be very helpful
