Just need a couple confirmations on the bottom 2 questions after so much research: I thought I would have to add all materials/shader's to every single object in an existing track before exporting. This halted my progress and seems time consuming as I am very familiar with materials in 3dsimed but learning 3ds max. I can get existing tracks into 3ds max with all the plugins settings directories layering etc Just trying to edit a few things on existing tracks (add some bumps, move some items, fix some wall cracks causing accidents) As my 3ds max skills improve I will tackle more Confirm: I can edit and export a single or a few gmts? (racsurface01 / wall01) Confirm: I can just assign a simple material export and sort them out in simed or material editor. I thought i would have to add all materials/channels to every single object in an existing track for exporting. OMG Any response would be so appreciated as I am so close to a workflow to see some edits in dev mod
