Can't get self collision to work. - roberthey - 13-12-2022
Hi,
I am working on a project which I got some inout on in a previous thread here (http://obi.virtualmethodstudio.com/forum/thread-3690.html).
I managed to achieve everything mentioned in the post but now I want to have self collision of the rope (wiener) and the pieces it gets cut into.
What I tried so far:
- Turn on self collision on the rope
- Increase the size and resolution of the particles in the blueprint I use
Problem:
No self collision. The pieces slide right into each other. Oh and when I turn of the bending constraints the rope also does that to itself.

Kind regards and thanks a lot for the help yet again,

Hi!
Particle collisions (of which inter- and self- collisions are specific cases) are globally disabled in the solver. You should enable "particle collision constraints" and "particle friction constraints" in your solver.
On a side note, you're missing packages so your simulation is using the default fallback backend (Oni) as the solver's warning message is telling you. This results in worse performance and limited platform support. You must install the required Burst package dependencies as per the manual's setup guide: http://obi.virtualmethodstudio.com/manual/6.3/setup.html

kind regards,

Hello!
Did as instructed. Works as always. Thank you very much. Splendid support.
The warnign went away without me installing the jobs package and I can't seem to find it in the package manager. Is that normal?
Best,
Robert

Yes, probably got installed automatically as a dependency of another package.
let me know if I can help in any way!

Will do. And again, thank you very much.
