2 rendering issues?

Check the Task Manager to check for memory usage.
Remember vfsu runs inside su, which is 32bit. The very max it can use is 4gb.I use 8gb mainly for Photoshop, I would hope I should not have to disable or remove my available Ram just for Vray.
I have found after 2 years of beta testing, its best to uninstall Vray when I'm not rendering inside SketchUp. Vray simply interferes too much with the normal operation of SketchUp, without Vray installed SketchUp almost never crashes.
I have upgraded several times my computer systems. I have 4 to chose 2 of which are netbooks. Without Vray, Sketchup loads almost instantly. My gut feeling after all this testing to date, Vray will never run successfully inside SketchUp, At the same time, I still hope my experience will be proven wrong.I also disable VfSU when I do not render - as I find it adds too much loading time and interferes with the undo stack. But I do not uninstall it. I disable it from under Extensions and then use my V-Ray Toys to load it on a per session basis.

There are many examples of superb photorealistic renders from vray for sketchup. A lot depends on three things - lighting, correct rendering options setup, and good materials. In your image my specific comments:
lighting: add some spot lights to shine on your cabinetry, the main problem looks to be too low lighting
options: I'll pm you a visopt
materials - add some materials with reflectivity, bump maps, good seamless textures, etc to give your rendering a more realisitc feel.Andy

Vray it's a very powerful and adaptable render, but the SK version it's a dumbed down version
I hear these sentiments often on this forum and would have to disagree. Yes, you are limited by 32 bit memory and yes, there are some additional perks in 3ds Max, but the underlying algorithms in the engine are the same, regardless of platform. I would only have to steer you toward the work of Teofas, FreeAgent and others who have shown what Vray for SU can do in the right hands. I think there is a general assumption that somehow opening this same scene in Vray for Max will magically render perfect in situations where it's failing in sketchup. It's simply not true. I'm speaking as someone who spent the money based on this faulty assumption. I have learned to love and do prefer Vray for Max for a lot of reasons, but instant push button quality with little knowledge is not one of them.
Tomot, issues like that of the blotchy furniture could also be a material and /or lighting problem. Can you post the file to have others take a look?

Hi EarthMover
I didn't say that to sound like an insult and my apologies if it sounded like.
What I meant was that everything that you do in VrayforSK can be done in VrayForMax, but the other way around it's not true. And if they both use, basically, the same "technical" language, IF YOU CAN, use the more complete version (unless you don't do big renders/complex scenes or don't need the other features missing)I never said nothing about "one-button-does-great-render" on Vray for max...I know there's great work done in Vfsk...as there's for Vfmax, maya, maxwell, mental etc. etc. they did the model, scenes and images not the software. And, if I may say, you should had try to inform yourself better before buying any software (marketing and other people's experience can be very misleading), because there's no rewards without study, patience and hard work in this area.
Best Regards
David

I would take issue too with the "dumbed-down" comment. The vray engine is certainly hampered by sketchup's limitations, but it doesn't make vray itself watered down.
-
No worries David. I was more or less just refuting a common sentiment that I hear often on the forum. I thought a lot of inexperienced users may misinterpret what you said. Vray revolutionized rendering solely because of the unique way Vlado performed his raytrace calculations and did it in an open framework. Not all that much has really changed from the initial version of Vray, way back when. Some things have been streamlined and different assets added, but at it's core engine, Vray is performing the same calculations, regardless of what software it is running within.

V-Ray takes a lot more work to get right than other engines that does brute force rendering and therefore able to simplify the UI. However, I still use V-Ray despite it's a steeper learning curve because I can get some really low rendering times when I need to in order to meet the deadline.
Though, the current issues with the Rendering Spawner in VfSU makes it troublesome at times... The takeover by ChaosGroup disrupted a lot of ASGVis plans for VfR and VfSU. They where getting close to finish up the development of VfR and merge the development between the two products. But after they became ChaosGroup USA they had to add some more features to VfR in time for SIGGRAPH. So the VfSU development suffered a delay. But I'm looking forward to when they are back on track because VfR got some really cool things: Proxies!
and Light Domes so one can light a scene with HDRI and get sharp shadows. -

thanks! tt I will investigate that

Earthmover: Simply download any Kraftmaid kitchen cabinet, and see how it renders.

interested it seeing your results! -
I don't think anyone here is trying to discredit Vray, although I have always felt a disconnect between the easy use of Sketchup versus the professional nature of Vray. Watching a superb 10 minute Video of how to create lighting for one living room lamp in Vray, does not inspire me to attempt to do the same to illuminate 20 other lights in a scene, including the time it takes to render unfavorable outcomes.
