Opening a scene that contains a shader with a vraybumpmtl will completely crash max upon start up.
Can we get an updated version of vraybumpmtl for 3.0?
Yes - VrayBumpMtl is already available for 3.0 and it works fine with materials created with 2.4 opened in 3.0.
Please follows the link bellow in order to update VrayBumpMtl for Vray 3.0.
