Making heavy/complex mesh objects more lightweight?
Sorry for the confusing title. Here's the situation:
I'm using Display Modes for a drawing project. I have a primary display mode set for the viewport, but the objects within the scene need to have another display mode. These objects are generally imported Sketchup files that are converted to meshes. They usually import as nested block references, and the only way I can get the proper display mode to carry through to the geometry is to explode them, but when I do this they start to really slow down the software. Is there any way to deal with these in a better way?
