Physics simulation with many complex objects (instancing)


for my latest project I want to use quite a lot of complex identical high-poly objects that should interact as rigid body dynamics.

This question is about true instancing in cycles mainly.

I want to use a low-poly mesh of the object for faster physics-interaction and put the complex object inside each lowpoly-object (parenting).

My question is which method would be best to achieve fast render times with instancing.

  • Linking the complex object from another blend-file (tried that, but couldn’t parent anything with that)
  • Duplicating the objects with ALT+D (duplicate linked)
  • Any other suggestions - maybe like using proxies?

The examples with really fast render times I found were mostly made with particle systems (like the tree island) which I think I can’t use in my case…
