How does VRayDisplacementMod works with instances?

[Art48]

Hi,

If I got 400 instances of an object with VRayDisplacementMod on it, how does it work?

Will I get proportionally more RAM load? Only when distance/pixel based subdivision is active? Will it change when I do world units based displacement?
Just curiosity.

I was curious about the results of this setup and did a quick test. So the memory usage is quite high without optimization. By optimization I mean bucket rendering with brute force or/and Irr map GI to take the advantages of the dynamic geometry and have more control by adjusting the Dynamic memory limit value.

V-Ray will replicate each instance and displace it separately.

If you need to save RAM, it might be better to use the 3ds Max Displace modifier.
