I am bit curious about optimizing a scene especially in terms of RAM/VRAM usage. I did some digging and found out that Blender is equipped with object and group linked instancing. You can copy instances object that are linked and therefore share same object data. You can also make groups of object in another seperated scene and then linked them into your primary scene as and “empty”. Especially the last one looks like a v-ray proxy system that I am familiar with. Now I wasn’t able to find more info about actual impact on RAM/VRAM usage while using such a kind of instancing. Could someone enlighten me please? Would this save me VRAM usage when using instancing significantly, is it worth it? Is just object instancing (in same scene) enought or is GROUP instance link from another file better? I ask because VRAM limitation is kinda tricky (atleast for me).
Thank you for clarification, I somehow got it like you are describing but I wasn’t aware of that many options of object instancing. Mainly thanks for clarification about memory savings that was really helpful for me! I will check out that link.
