Displacement Mod & RAM

[Macker]

Hey guys/girls,

I have a scene with lots of grass areas, not enough time to sort out geometry grass so am using displacement which is doing the job just fine in a few of the shots, however for some of the shots the ram usage goes through the roof and the render slows down to a snails pace...

I know how to adjust the edge length, etc and it does make a difference to the speed, however the quality isn't enough. My question is; does it make any difference at all whether I have one vray displacement modifier on all of the areas of grass, or whether I assign each area of grass its own vray displacement modifier?

I suppose ultimately with it being view dependant, probably not... Just thought it was worth asking the question.

Nope, no difference at all. The result in both cases is exactly the same.
