Here is a scene I'm using as a reference.
Here a portion of a trailer assembly not fully finished using for reference to show what i mean.
One of the trailers alone has 673,475 tris / 269,538 faces / 428,851 verts, and its not even fully finished yet its about 25% complete and there will be from 4-6 of them in the scene alone not including everything else.
Here is how the frame looks like in edit mode.
So before i continue should i just recreate everything in blender or is there a way to reduce the amount of vertices?
I just don't want to waste time placing everything and my computer giving up.
I've used the edge split modifier with the smooth shading tool, limited dissolve, remove doubles.
