Hi, thanks for reply, this is rendered with the production renderer. I have also tried to create the cloud manually and with a preset and the same thing happens in both instances. I suspect its something to do with the shader material, although it says on the V-Ray website that particle (pflow) is supported by the Vray RT GPU. (The cloud renders normally with V-Ray Adv) Is this a problem with the setting in Vray RT GPU? or is it because of an unsupported featured and nothing can be done about it?

Hi can someone please explain to me whats happening when I'm trying to render a cloud preset with Vray RT CUDA?

I have found a solution. The problem has been caused by the 8 Bit Texture Format setting in Vray RT Settings. Thanks to everyone for trying to help.

Here's the original and the render on a Vray Light Material.

Here's an original and the rendered version placed on a Vray Material. There are also other light sources in the scene.

Hi, I am getting some horrible results with the bright portion of the image looking perfectly fine and the black shadows looking awful. I suspect that this is some kind of a contrast problem. The image looks exactly the same like that without any rendering in 3Ds Max 2015 and 2016. I use Vray Material and then choose bitmap and put a high resolution jpg file on top of it which looks perfectly fine in windows. Thanks for looking. Please help.
