Imagine a car park with hundreds of different unique vehicles, each 1.000.000 polys+. Impossible to load that scene into memory or even work with it.

Only way I see is to use proxies with a very limited amount of prims and have a file path which loads the geo if needed during the render takes place.

The purpose attribute with render/proxy seems to be kind of the way to do it, but the geo can't be kept in the scene memory. This would be a jut a solution to speed up opengl work, but doesn't overcome any limits set by the physical memory in the pc.

So, how is this practically done? With instances, with a special attribute, or something else?


Would love to get some input on this.
