Quote - In most cases a prop is just an obj and a texture. I'm wondering how significant the memory savings would for an average prop to reference an external obj.

That's an important question, for the effort involved in saving the memory of something trivial is probably unjustified. Your typical prop is pretty small - and almost never loaded twice, let alone dozens of times.

But - still. If it were a bar glass, or something similar, that gets replicated even in a real life setting, then maybe it's worth it.

Blades of grass - absolutely worth it. Which is why it's so important in general, but not so much to the NVIATWAS crowd.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
