Instance or Mirror

[doublez]

If I have a few objects that need to be on both sides of an axis, would it be more memory efficient to instance all of them or mirror half of them?

i think in any case instance is going to be the best. because instance saves the mesh info once and the applies modifications from there. mirror will basically double your mesh. making 1 mesh but with twice as many vertices.

id go with instance.

That's what I was thinking. I was mirroring everything but I ran out of ram just now on a test render so I need to figure out how to save some memory.

Mirror modifier in blender is generally intended to help in workflow of modeling things that are symmetrical and will save you memory there but not in final output.

I instanced a few things that were used a lot and was able to render. Just now I instanced everything that could be (somethings need to be mirrored still), so I should be in a lot better shape now.

Thanks guys
