You have USE COLOR AS TRANSPARENCY ticked on. Turn that off. I would also load a glass vismat from the Chaos site, something with reflection and refraction.

That suggestion is useful.

Cheers for this... attached is how its looking so far

(double sided tick box in option in mat editor)

This tick box only means that the material will be applied to both sides of the polygons.

A Vray2sided Mtl is a really special material. It allows you to have different materials between the front and back sides of your polygons, and blend these two materials together (and the light they receive) depending on a grey value (or map).
This allows you to mimic translucency for very thin objects (one face only): Paper, leaves, curtains, etc.

Thanks for the explanation Jiminy - that's a really powerful technique.

1.6 was a beta and that is over now. We are now on 2.0 and this was a bug that was fixed.

You need to subdivide you're sphere more to give V-Ray something smoother to render. I'd Suggest manually making your sphere using circles with more sides (48-64) or using a plugin like Artisan to subdivide and smooth your surface.

I believe the 4 light restriction is due to you using the Demo version of the software. If you upgrade to the full version that should go away.

Please contact support@chaosgroup.com. We can help you with your issue more efficiently if you contact us directly.

Do you use its render feature? How does it integrate your workflow?
Do you see how it could be improved for rendering?

(I'm the author, I would love to hear your feedback on this. And what CG USA in general think of it)

Glad I could help!

would you please guys explain more how to do it in details and step by step please
best regards and thanks in advance

Again, I can't help unless you give me a little more information to go on. Open Sketchup and go to Plugins> V-Ray> Open Debug Window. What is the full version of V-Ray that you are running "2.00.XXXXX". There is a service release out that fixes a lot of the issues with RT. It could also be an incompatibility with your computer system so specs of the computer are useful see thread: http://sketchucation.com/forums/viewtopic.php?f=322%26amp;t=26019.

The more information you provide, the easier it is for me to help. "RT bug-splats when I render." is not helpful when trying to track down a problem.

What are your specs? I downloaded your model and it rendered in 2 minutes after I changed the settings back to default. I noticed your Dynamic memory limit was set to 10,000. Don't do that. Im thinking that might have been the problem. Leave it as a default setting, or set it to 1024, 2048, or 3072. This is how you allocate your ram for a rendering to prevent crashes. The lower the number the slower the render (on larger jobs), but it also makes the rendering process more stable.

Hi marekorv,

Could you please email support@chaosgroup.com with this issue and send a packed scene and model so that we can test it? To pack a scene go to Plugins>V-Ray>Pack Scene, this ensures we recieve all the associated assets.

In the meantime you can try some things to see if it will fix your scene:

Force Sync all materials: Go to Plugins> V-Ray> Debugging> Force sync all materials Try Copying all of your geometry into a new clean empty Sketchup scene. Be sure all associated materials/textures are in a location on a local drive that V-Ray can access.

Let me know if any of those solutions helped and when you contact support, let them know you spoke to Ted in the US office initially via the Sketchucation Forums. You may also want to look in the Forums on the http://www.chaosgroup.com website for other solutions to this issue.

And in my opinion, the elevation you want won't benefit from rendering that much. The benefits of a rendering vs a sketchup elevation has to do with material and light, right now your reflective material looks flat because there is nothing to reflect, just a grey background, try adding a billboard or something to reflect behind the camera. Secondly, the lights have very little material to lighten, the glass has a bit of reflection of the light but nothing more. Maybe add a floor plane to show the effect of the lights.

This may also have to do with image resolution. If your image is noticeably tiled, than your grass displacement will look tiled as well.

Hello -

I was wondering if I could "reprogram" a mini usb (flash drive) and use it as the Vray dongle?

I'm on a laptop and it would be super nice to utilize something smaller. Working from home, at the office or in a client's office it's terribly inconvenient to always be locating, plugging in the dongle and then starting up the license software. What if other software packages required a dongle? I love Vray, but this is extremely annoying.

Thanks in advance,
Joe

Sorry Joe, In the future we will move away from the Dongle but for 2.0 you're stuck with it. However, you can set it up as an on-line licensing system and host it from a home computer or work machine. Email us at support@chaosgroup.com and write in the header Attn: Ted Vitale and I can get you somebody who can walk you through the process if thats something you would like to pursue.

Thanks alot guys!

I had the same problem. Rectangular vray light, inside component. I JUST RESTARTED SKETCHUP and the problem was fixed!

Explain how its crashing, is it a Bugsplat, or just an RT crash? I just downloaded the Demo to test this. The output is limited to 600x400 maximum resolution. If you change your resolution settings while RT is running it will crash. This is not a supported workflow.

Like this!!!!! Thanks . Hope vray 3.0 comes out soon with fur and more feature !
