@jgjYRRKE Cool looking machine, would make a nice image for the Friday pictures!
As for rendering with 3DS Max:

Starting over with finding materials for an assembly like this would take me a very long time:
SolidAngle provides a somewhat basic material library for Arnold here:

(download link is the word "here" at the bottom, in the grey bar)

If the model contains a lot of parts then i find that adding the right materials take FOREVER.
There are some tricks to speed up that process, i'll try to detail it a little here:
When importing your Inventor assembly/part into Max, make sure you have the option to import Inventor materials and assign ID's checked.

When imported, you can then import all the scene materials onto the "Slate Material Editor"

Once that is done, if you right-click on an imported material you have the option to "change material/map type"

You get a list where you can select other materials, so if you've set up a material library then you can select any other pre-made materials. (like the one i linked, or ones you've made yourself)
It probably still needs some tweaking after that, but i hope this makes it a bit more interesting to try Max. 😉
