Maya Physicalise Material Problem

Mathew O

Hey guys, I'm having issues physicalising my materials fro the cryengine, I'm going to extra attributes in Maya and changing the drop down box to default and then adding it to a material group and exporting. This has worked for me before so i'm pretty sure i'm doing it correctly but when i get it into the engine and try and bump in to/ walk on my object it doesn't work.

Any ideas?

Thanks guys

Ah ignore me, I figured out it was because I was applying the same material to over 10k tris and that turns off collision
