Vray RT and Forest Pack Pro

[Nicinus]

I must be doing something simple the wrong way, but I can't get any of my Forest objects to render in Vray RT except for the ones I'm using from the library, a mulch and a grass preset. None of my trees, mostly purchased from various sources, shows up. Everything works well in the regular vray adv render.

According to Vray Messages I have about 2GB available out of the 6GB on the card. I'm using 3ds Max 2016, Vray 3.40.01 and FP Pro 5.0.3.

Any ideas?

O'boy, very embarassing but there was a switch (VrayProxy objects that for some forsaken reason is off by default.

For new scenes with 3.40 it is on by default .

Thanks Blago. At this point I was mostly experimenting, but in the end the scene didn't fit anyway.

Makes me wonder if onboard GPU memory will ever catch up for architecture. It would be fantastic with some sort of mechanism that, in the case of a scene that was too large to be loaded, Vray could list the 10 largest offenders so that one could uncheck/hide some of these and try again. I did this manually with Forest Pack objects but it was not always clear which took most space, and how much I had to hide. If this trial and error process could be simplified it would be a good bridge until memory becomes less of an issue.

Nice idea! Btw, we do print how much memory we spend for textures/geom/etc. We plan to reduce the memory requirements for the next versions of V-Ray RT GPU, allowing you to load more stuff for less memory. This is wrongly called out of core rendering sometimes, I guess because it sounds better. The first part of this is already in the developer nightlies.
There are a lot of clients using RT GPU for architecture, but I guess that it depends on the specific case.

Keep us posted if you have any issues with RT GPU in general .
Best,
Blago.
