Beyond things like the import/export process, art created for RF-X also has some different requirements in Max. Examples include working with transparency and different names used for tagging some parts. That is because RF-X is built on a completely different engine (Unigine).
For RF8, the creation process in Max should be the same as for previous generations of the product like 7.5 since they share the same engine.
