Vray RT issues

[ANDREW_DECKER]

Hi, I'm having a couple issues with RT I'm hoping I can get cleared up.

First is texture maps. If I do RT with CPU everything looks fine and texture maps are rendered properly. Problem is RT with GPU my texture maps are ignored and materials are rendered as their base material. To be specific it ignores image maps applied to the diffuse color channel. I'm using a GTX 580. It's much faster than CPU but not very useful if it's ignoring maps.

Other issue is I use a render farm of 10 computers. If the farm computers are off and I turn on RT it takes a really long time for RT to begin because it is looking for all the computers on the network and not finding them. If I turn off distributed rendering in the option menu it still tries to connect to the other computers on the network. If the farm is on RT starts up pretty quickly. If I disconnect from the network the RT starts really quickly. It doesn't matter if I use RT-CPU or RT-GPU, same results every time.

Thanks, any insight would be appreciated.

So it sounds like GPU doesn't REALLY work. You can get an image really fast, but it's not going to let you know what your production render will look like.
-RT-CPU
-RT-GPU

Does anyone have this problem...you turn off distributed rendering in the options panel and when you start a RT Vray turns distributed rendering back on, everytime?

There are still a lot of features that are not supported on the GPU - you may check the list bellow:

According to the other issue with DR - Vray RT and Vray ADV have a separate options for Distributed Rendering.
Did you disable DR from V-Ray RT Render Setup window?

Which V-Ray/3DSMax version you are using?

I'm using VRayForRhino5x64_2.00_24932 and Rhino 5 SR9 x64. VrayForRhino doesn't seem to have the option to disable the DR from RT. That would be a nice thing to have. Right now if I don't want DR with RT I have to disconnect from the network. Not that big a deal except some of my programs have trouble finding the network without a restart.
