trying... thank u...

Thats what I do. I map the drive the same letter on both machines. I would highly recommend that you backup the drive either to another external or locally on your home machine. Portable drives are highly unstable. I almost lost a lot of data this past year.

I've been having the same problem. I tried lights off, materials overriden, no physical camera, minimal render size, nothing would work. Finally I noticed I had the options set to auto save the render on the server path (which is not my machine). This was working before, but I guess if the ip adress changes(or something network related, I'm not an IT expert) vray just doesn't know where to save the file, and produces this kind of bug. No error message, no log entry, nothing besides a black render which is proccessed extremely fast. I guess this may not be the only cause, but it worked fine with me. Hope it helps. Cheers!

Im currently using the Vray 1.6 Beta, but the materials are all the standard Vray basic material pack. I bumped the glossy samples up from the base 8 to something like 25. Im not at the office right now but later I will be so ill check on the material settings. Truthfully I think its in the render settings and not the material because it happens across the whole model with any material that has some reflection to it.

you should put something similar to a bump map with a black background in the perpendicular slot of of fresnel map, that will give nice reflection effects on the leaf and no reflection to the transparent bits

You could also try to use two diffused layers. The back one with the actual concrete texture on it and then cover that with a colored diffused layer with a transparency perhaps. Just a quick thought in my head. Rob

you should select text bitmap and then you can add the proper link to your file. [image: fjih_TexBitmap.JPG]

@cuttingedge said: I think my trouble is more with sketchup 2013 than vray. the rendering part is smooth but I had bugsplat after bugsplat in the modeling part. which I think has nothing to do with vray. It's a gamble for you to install Vray 1.6 on SU 2013. YOu may acquire a license for SU 2013, but keep the vRAY 1.6 beta on your more stable SU like v8. In my experience, it's the opposite... I first installed Vray 1.6 on SU8, and got bugsplats over bugsplats while modeling (I guess due to Observers used by RT). So I loaded it only when needed. Then I moved on to SU2013 and have much less bugsplats.

i learned v-ray on the demo a couple of years ago. while for work i generally use thea render, i have to say a few days into this version and i am very pleased - feels friendlier (love the fresnel by default!), it's fast and the tweaks are clearly geared towards the user. by the time SU 2014 comes out with 64 bit support - you won't need much else. (i can just imagine another extension warehouse for all the max plugins ported to SU).

There is good chance that the OBJ file you are using doesnt have materials applied to it. There is a tutorial I made up on the Chaos forums for using Blender to make vrmeshes. Try this method.

sure will;)

great, and you sent it to vfswip@chaosgroup.com?

yes, same result - i'm going to try with different subdivs cause i have a feeling it's somwething to do with the shadows. the tall cube is not touching the ground but about 2cm off the floor..

1.49.01.. i have maybe a big scene.. its about 160MB. and i cant render.. still writing.. weve encountered an error.......

good to hear, I look forward to seeing this bug in our bug tracker.

Nice ! Can't wait to see the whole guitar

@valerostudio said: What is the version number? Sorry forgot to mention that, Sketchup v. 8, V-ray v 1.49

you may change the background, or also put some hdr maps in the reflect slot, or maybe create some coloured light sources which are invisible to camera but affect reflection..
