Is the parent material type (VRayMtl) corresponding to the VRayMtl in 3DS Max strictly?

I noticed that the parameters of VRayMtl between UE4 and 3DS Max are different, and could I map the corresponding parameters from 3DS Max to UE4 manually?

If it can be done, how can I do this?

Thanks for any advice.
