mesh collider not working

[Duncano]

Hi, 


it appears mesh colliders no longer work.
we are doing a HDRP project in 3.13

(Support Unity versions
2019.2.9 or higher) 


Most things seem to work in 3.13, but mesh colliders do not...is this correct.

basically trying to get objects to collide in a cylinder ( while avoiding arraying a load of boxes)

thanks in advance.
