Material selection problem - Inventor assembly import

Anonymous — Tue, 11 Nov 2014 09:40:31 GMT

Hi guys,

I've modelled up an interior apartment scene as an Inventor assembly with the a view to trying some rendering out on 3DS Max/Vray as Showcase just isn't realistic enough. I'm fairly savvy with Inventor, but very much a novice (at the moment) when it comes to Max.

There are a few issues when I import but the main one I am struggling with, is assigning materials. At first, 1 material would be applied to everything in the scene but after reading some posts in the forums, I now know I can "ungroup" and apply individual materials this way. Perfect I thought...

.. BUT I'm still struggling to apply different materials to the actual room, i.e the walls, window glass, window frames, ceiling as I have modelled these as just a single object in inventor, not an assembly, so it isn't possible to "ungroup". I want to add a feature wall and dark wood window frames for example, but I can't because it selects all the features of the room. Is there anyway round this?? Maybe a way of selecting patches and applying materials to an individual patch??

Apologies if this is a stupid question or has been covered before, I have looked through the forums but couldn't find anyone with this specific problem when importing an inventor model. Also, I currently have only basic knowledge of Max and Vray so not sure where to begin.

I'm running Inventor 2014 and 3DS Max 2015 by the way!

Hi. You need to give each part of the object a different material ID and then apply a Multi/Sub-object material, containing all the different materials.

You assign different material IDs in the editor roll out (right side of display). Activate "poly" (sub-object level), scroll down to "surface properties", select the polys and assign material IDs.

Each ID should correspond with the material IDs in the Multi/Sub-object material, ie 1 for Wall paint, 2 for Window framing, 3 for Glass etc. etc.

Hope it helps
