Perhaps there are some bugs, or maybe I am using the wrong method

Thank you for reporting these issues.

Nr 1 will be fixed in the next hotfix release.

Nr 2 is I believe is a scaling issue between Pyro and Arnold (cm v m). You have to multiply the displacement by 100.

The crash with metal presets is now fixed in C4DtoA 4.7.2.1.
