Does ph_cylinder work as a physics hull type in 6.31 ? When i choose it as a hull type in phent_settype, the entities do not appear, but it works fine if i use ph_sphere.

Also, would it be a good idea to use cylinders for car wheels?

Ph_cylinder does not work right, I dont believe it has actually been fully implemented. Use ph_sphere for car wheels, it works well and I never had any problems with it.

Thanks

Confirmed.
