Help Strange sagging behaviour

[josemendez]

Thanks for the replies. I think I understand how collisions work and I dont think that is the issue, but have posted here to double check. 

My connectors on the end of the rod have collision catagory 1, and collide with everything except 0. My rod particles have collision catagory 0 and collide with everything except 1 (is it fine to have 0 (self) selected here?).
If I have a second, inboard, particle then with will have all collisions selected, but the issue is independant of this so I dont think this is relevant.

Hi!

I believe the fastest way to diagnose this is by taking a look at the scene itself. Would it be possible for you to share it by sending it to support(at)virtualmethodstudio.com so that I can take a closer look?

thanks!
