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!

Hey

Could you not create a rest attrib at the sop level and then use that as the position that it set on the Geometry Wrangle?

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)

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

You could use v and w attributes to restrict Z Position and Y Rotation, I got this simple example.
Hope it helps.

Alternatively, you could switch to Blender...

That definitely help, thanks a lot!
