Hi Does anyone have some tips/research/reading materials on methods of combining massive Revit models from Revit to Unity 3D on a commercial scale?. That is to include 100% detail - pipes, ducts, walls, floor, Structure, fittings etc.. into a Unity walkthrough. I have been doing for some time now but it takes a very large amount of time optimizing and combining mesh material within 3DS Max - especially with Revit meshes from MEP packages i.e. the most polygon dense models. I have simulated a few mega models but none with 100% detail - I have always had to ignore smaller detail (with high polygon count) as a result of Unity crashing at that stage from excess content. So I wanted to start a discussion on - what are the best methods for porting & simulating 100% detail for commercial scale mega 3D models into Unity from an AEC based application - such as a Revit.
