Title: Can FP utilize 32gb / 64gb ram ?
Post by: BB1610 on March 10, 2013, 10:32:16 PM
Hello friends,
I`m deciding whether to get i7-3770k and 32gb ram or i7-3930k and 64gb ram, and my question is, can FP utilize such amounts of memory ?

Thanks for reply,
-Radomir

There are not specific restrictions in the amount of memory that Forest can use. The plugin uses the memory mechanisms provided by Max.

Thanks fpr the asnwer :)

Just one more question - can you roughly estimate (if possible) the scale of forest objects, or polycount, which could populate 32/64gb ram via FP?

It is very difficult to estimate those values, because is not as simple as multiply the size of the tree for the number of items. Also that depends also of the render engine. We suggest not use more than 4 to 5 millions of items with VRay and 500k for Mental Ray, but only for efficiency reasons. Over these limits, the scattering and render times would grow exponentially.

Anyway, with 5 millions of items, probably you will get more plants that pixels at screen... and it is not needed much memory to get this density (probably about 3Gb using a unique plant model of 1 Million of faces).
