That sounds great, because I need the rope to be in a special layer for lighting purposes, but I forgot that the rope needs to be in its own layer for collision purposes. But I'm still having real trouble with your .dll files. Even though I've rebooted my computer since the last time I mentioned this, for some reason the .dll refuses to unload on my machine: EDIT: This happens BOTH on the work Windows 7 machine and on my home Windows 10 machine. Is there anything our IT staff can do to help diagnose this? I am unable to upgrade to 3.1 because of this. EDIT: I tried to press "Cancel" which apparently installed everything but the new version of the .dll, causing Unity to crash. I then tried to revert by copying the Obi folder from the backup machine, but now I get the following new error: I'm currently locked out from using Obi Rope in my Unity project.
