V-ray 1.6

at that time, the statement was accurate. GPU rendering was added during our beta process. Originally it was assumed that this addition would take too long, and would potentially be too unstable to add to this release. We have it working now, although it is limited.

so its working since what version? And is it automatic detection or the user has to select GPU rendering? (I suppose it does not support ALL features of CPU rendering?)

Available for final rendering or only for RT?

It is in the Beta version so it has not been released yet. In the options under RT you have to choose GPU....

I am not sure about what it supports....

GPU support does have some limitations. Here is the documentation for what is supported: http://www.spot3d.com/vray/help/rt100/supported_features.htm

and here is what is unsupported:
http://www.spot3d.com/vray/help/rt100/unsupported_features.htm

Obviously the 3D Studio Max specific stuff isn't relevant, but for the most part these documents apply to V-Ray for SketchUp. It's recommended to use CUDA over the OpenCL method, if you have an NVidia graphics card that supports it. If the chosen GPU method isn't supported on your machine, a message should appear in the progress window indicating that CPU will be used instead.

We are well on our way to final release though! RC2 should be our last Release Candidate prior to release, so everyone get ready!

I am attaching a screen shot of Render window using a full render. I am also attaching a render window using RT CUDA GPU, ....I waited about a minute and this was as far as it got.... notice the walls are black and nothing really looks the same as the full render. I am also attaching an image of RT Using CPU... this one is much closer to the full render using Render button. I got a similar Result using Open GPU as I Got using CUDA GPU... I am also attaching a screenshot of my system...

Maybe someone over at Vray can take a look at this and tell me what is going on? Not sure what I am doing wrong or what I should expect with RT but it seems a lot slower than what I saw on the webinar the other day... and the GPU is not looking right?

I am using 1.6 23412 which is one of the latest nightly builds.... so...

Thanks, loving the new Vray,

you know, certain material types, like diffuse, aren't necessarily supported in GPU...

Just kidding! you probably have reversed faces on your walls. RT is still a work in progress, there really are some material types that aren't supported or don't render the same way as the regular render.

The more lighting sources and the more reflections you have, the slower your render will process.

That's nice that you got the GPU render to work. I have an older card in my machine and I never got around to finding the proper software to try it out.

we could try to replicate the issue in our office if you could send us the scene. There is an option under Plugins->V-Ray that is called "Pack Scene". That will grab all external files, such as textures, as well as the scene file, and bundle it all up in a .zip file. Just send us the .zip (ftp server if you have one, dropbox, box.com, soShare, media fire, etc) and we can test here at our office. Send an email with a link to the scene file to vfswip@chaosgroup.com hopefully it's just a setting that needs to be adjusted.

in terms of getting rid of the watermark try resetting your light cache in the options menu...been surveying forums for a solution to no avail, but this seems to do the trick

dkendig

the 1.6 beta is over, the 2.0 version has been released. Does resetting the light cache get rid of the watermark in the 2.0 demo? The 1.6 beta should be expired and always have a watermark at this point, is it still possible to get rid of the watermark by resetting your light cache now?
