Basically make sure your Nvidia drivers are up to date and that you don’t have the Geometry Editor tool selected. Use the pointer or universal tool instead.
Thanks MJC, but that post is mostly talking about hair not being visible (rather than not simulating gravity).
I’ve seen this video where it discusses using dForce enabled clothing, no need to add dynamic surfaces or anything just run simulation straight out of the box:
I assume the same should be true for dForce enabled hair but it does not seem to work for me.
Do you use any dForce hair in simulations that work for you? I might try them and see if its just an issue with the hair I bought or not.
