Vray 3.6 can use either one and even use them in parallel via CUDA. Still I am myself not sure if I should first upgrade the CPU or GPU under these circumstances. I lean towards the GPU as the card I am considering Quadro M5000 can live with my existing power and cooling systems of the HP Z800.

Hi, I am working in architectural visualisation, predominantly I create spherical 360 degree still images. Picture size typically 12000 x 10000 pixels. Rarely I render movies (yet). So far no gaming at all. Still want to test game engines for rendering in Arch Viz (not for gaming though. Apart from that, I do work a lot with Affinity Photo on very large files with hundreds of layers. To do this I use Vray 3.6 for Rhino 5.0. Vray can now handle the combined use of CPU & GPU via Cuda. Still, when doing this the images turn out grainy/noisy despite the denoiser beeing on. CPU alone rendering works fine and gives good results, but is slow, that why I want the combined power. My current graphics card Quadro 5000 never shows much usage in the Nvidia GPU utilisation graph when rendering but its memory gets fully used and I get an CUDA error 2 : unable to allocate enough memory to perform the requested operation (out-of-mem). I suspect a settings error. Neither Rhino or Vray are listed in the "3D Settings" field of the Nvidia control panel and I wonder if someone can recommend the best settings to choose. At the moment I use the the 3D App-Visual Simulation Profile with: -Open GL Overlay switched on -Power management to Max -Tripple buffering on -Vertical sync on In the following the spec of the machine. An upgrade to a Quadro M5000 and 72GB of RAM is planned. My machine has the following spec: HP Z800 2x Xeon X5650@2.67GHz 24GB RAM (soon 72GB) Quadro 5000 (soon Quadro M5000) Driver 377.83 Windows 10Pro 64Bit latest release Rhino Version 5 SR14 64-bit (5.14.522.8390, 05/22/2017) Vray 3.6 for Rhino latest release I'd really appreciate if someone could suggest the best settings for the current graphic card. I am less after on screen display quality but much more after final result quality. Apart from that should I get the Quadro M5000 or better a GTX for my work? Suggestions? The Quadro M5000 has 8GB GPU RAM, the current Quadro 5000 is old and has 2.5GB. Thanks so much, Franzi

Hi everybody, I am currently working on a demo image with a very large building and have trouble with rendering it without spending ages. It's doing it, but its a big scene and resolution is high with about 5000dpi. The file is running into the Gigs's by now, as it has an aweful lot of detail in it & I have already cut it down considerably. Here some details. Maybe someone can shed some light on how they approach this typically. Many thanks for your suggestions! The details: Building is about 20 stories high Round shape Lots of glass outside walls therefore the need to show lots of interior stuff as well Full interior (all Vray proxies) with over hundered desks monitors and the likes visible Lots of outside frames of old cast Iron lattice structure type struts with lots of details (I built them already as simplified boxes by now with transparency mapped details instead of fully modelled) 15trees (all Vray proxies) Surrounding city & terrain (simplified boxes via Openstreetmap model) Many complex reflections in the glass facade from struts, trees.... Grass surrounding Carpark with about 30cars visible I've already hidden (&switched off) all strip desk lights and stopped dreaming of nighttime illumination before post production even though I'd love to do it in arendering I did hide anything not visible in the model and than even deleted that geometry from the model. Purged unused materials. For testing I use the Vray exterior scene medium quality presets, but added a vray sun and GI lighting from an image. Normally I'd use ligh cache instead of Brute force, but figuered the presets (which suggestBF) might be more pretuned for performance. Caustics witched off Prepass reduced to 1 (low res test image came out fine) Physical camera Dynamic memory limit 22000 I'm running on a HP Z800 workstation (Two Xeon X5650 6x2,66GHz) with 24GB Ram & a Quadro5000 graphics card. Software is Vray 2 for Rhino. I did notice that at first both CPU's run 100% than RAM gets used up fully and CPU performance drops eventually to 10-20%. Guess its reading from cache than as the SSD is working near 100%. Maybe its time to get more RAM? 64GB Win with distributed rendering switched on (I can see all my 24sheep (=kernels) on their meadow (=renderscreen) but they graze really slow ;-) So, looking forward to your suggestions. Thanks for your thoughts!! While I appreciate suggestions how to speed up my specific process very much, I am primarely after understanding how anyone doing such scenes regularly would approach this from a workflow perspective.

OK. Found a way to do it with custom mapping & offset surfaces (shadow on these are switched off). Still a method which allows free relocation of the stickers would be better. Anyone?

Hi everyone, I am using Vray for Rhino 2. I am trying hard to get some decals on an airplane. In Rhino thats easy with the decal command. Still, I need to render the final airplane in Vray. Unfortunately the Rhino decals do not show up in Vray. I tried for hours to get it to work, but noch chance. Is there anyone who could help? Attached the Rhinofile, two of the stickers and my Vray material as well as an image showing how it looks in Rhino render. The trouble is that I want to map several stickers onto one relativly complicated (=distorted) surface. I need to be able to do this quick and efficiently as this will be happening a lot in the future. So it would be mighty helpful if someone could share their workflow. I know that I could workaround by drawing the stickers on the model, but future stickers might be more like photo images in which case this would not work. Thanks so much to anyone helpful, Franziska Ps. : I had to cheat to get the model attached. please download the zipfiles: Falcon Jet Fuselage.zip Falcon Jet Fuselage z01.zip Falcon Jet Fuselage z02.zip Than rename Falcon Jet Fuselage z01.zip to Falcon Jet Fuselage.z01 Falcon Jet Fuselage z02.zip to Falcon Jet Fuselage.z02 and doubleclick Falcon Jet Fuselage.zip to open the expanded zipfile with the fuselage. Decal.zip has the Vray Material in it. Falcon jet 03.jpg shows the result I want, but is rendered in Rhino. The other files are some of the decals.
