Preparing Forest with iRay is taking forever...
« on: April 09, 2013, 09:17:59 PM »
Hi!

I'm working with newest verion of Forest Pro, Max Design 2013 and rendering in iRay.

Getting ready the scene with about 35000 instances (grass) taking about 20(!) minutes.

Can you check what's wrong?

I can attach the scene.


Thank in advance,

IRay is not supported by Forest Pack. This render engine doesn't support instancing properly, so instead keeping a single copy of the grass element in the GPU, it creates 35k copies.

We can do anything about that, unfortunately. It is a limitation of IRay.

Thank you!

I understand it, but maybe it could be possibility to convert Forest To Meshes (yes 35000 meshes... ;] )

I'm doing this with other multiple objects and iRay handles this correctly.

Yes, you can use Forest Tools (in the Utilities panel) to convert the items to stand-alone objects.
