Help Collision Detection

[josemendez]

Hi everyone,

I am having a lot of trouble getting a rope to collide with my character model.  From the reading that I have done in these forums, my guess is that my rope diameter is too small for accurate collision detection.  I'm using ObiRopes to act as IV tubing so I need them to be fairly thin.  Is there anything that I can do to improve collision detection?  Unless I change rope size, there seems to be zero collision detection occurring.  I have tried increasing resolution to 1 without any improvement and also tried adding more steps in the ObiSolver.  The blueprint path for the rope is generated through script with a diameter of 0.03f.





Does anyone have any suggestions?

Sounds to me like tunneling, plain and simple. Try reducing Unity’s physics fixed timestep (found in the time manager).

If you’re unsure about what tunneling is, see:
