VrayRT for CUDA

[jamestmather]

Is this to be a production renderer or just for previz like RT currently is?

Thanks

Hi Vlado,
It's possible that in the future VRay 2.0 or next release will use a GPU for accelerate the Rendering, like in VRay-RT?

[vlado]

Well, in future tense, anything is possible

Best regards,

that would be a really nice feature!

Looks really nice indeed, and the power of today's GPUs vs CPU is really interesting.

Will you get RT for CUDA when you buy a release of VRay RT or will it be a separate release?

I'm interested to buy VRay RT but would like to know about the CUDA/GPU release to be sure.

I am in the same boat as you. Did this get answered. Im sure the CUDA release will be included if you have the VRAY RT regular version??

[vlado]

It's too early to talk about this; I myself do not have a clue yet Things will be more clear when we get to user-friendly version.

Best regards,

RT for GPU use only Graphic card memory?

RT for GPU use only Graphic card memory?

Currently, yes - everything is uploaded on the GPU.

OK. thanks.

Will you be recompiling it to work with OpenCL? CUDA sounds awfully proprietary to me, which is never a good thing

[instinct]

CUDA -> OpenCL is not a mere recompile. Rather a rewrite. But still it was announced to be ported if i recall right.

Kind Regards,
Thorsten

+1 for OpenCL

Its the future imo.

Very good work regardless guys! Could this be used in production renders also or is it only in the working environment? Its my understanding RT isnt really for production but just to speed up feedback in the view port?

You can actually build a system with four 295gtx cards yourself (which gives you 8 GPUs).

BTW recently looked at iray... It's painfully slow with refractions on 4 quadro cards. In demo, called "car" there were some spotlights with direct shadows inside the interior (scene were lit with only one hdri). So the only soft shadows were under the car...

Other demos - well looked like a hardware viewport preview. Very strange materials.

Also there's no support for importance sampling. Hehe.

No scenes which can demostrate caustics.

P.S. Support only mia material. You can't write custom shaders. Will be released later in january. Still no connectors to max/maya/xsi
