As for the how to - just go to your options, output, get view aspect, click the L to lock it, then type in 4500 in the width box, with your aspect locked, the height will auto adjust. Also, with the aspect locked, your render will match your SU viewport exactly.

@damaiyanto said: but then if it is the light cache , does it mean there's no hope for using it? If you figure out which materials are slowing it down, you could try adjusting those problem materials (fewer subdivisions, use bump instead of displacement, etc.) then try LC again.

Thank you Andy for the info, I look in to that right now. Hi Chon, thank you for the info, I am familiar with the video but render in a cloud day is very dificult since the sky is almost white and there is sun but without power, at least alsways is like that here in Seattle. thanks again both for the info. kalu.

reverse the material or apply the material on both side.

If you are unsure how to proceed with instructions you received from our support department, please ask our support department for more details. We even will offer to remotely log in to your computer and fix it for you if we are unable to resolve the issue by providing you with instructions.

@valerostudio said: Displacement kills CPU, use it sparingly. Also, try to get away with using lower subdivs and and a higher edge length. On high res renders you can sometimes get away with an edge of 20+ pixels. Try it out. Thanks for good advice but in this situation i used edge length 1,0 without 'use global' option to make it real, full of details. Finally for the high resolution render i made it with fur plugin. it looks better i think:) [image: c39F_forum1.jpg]

I have already cut the animation down into sections to see if it would handle it better. Each section is about 12 seconds with a 60 frame rate. Could it be my scene just has too many elements? Would i perhaps be better using a different programme like 3DSMax?

Thanks, I'll try that technique for sure.

There is documentation out there if you look through the net. Between all the videos on the Chaos YouTube page, the manuals that exist for the plug-in, and other V-Ray for Max sites, you can get a good handle on this plug-in. I have to admit it took me a good year before I was comfortable with it. So plan on putting some serious time into it. But once you know V-Ray, you can use that if you move on to MAX or Blender, so it pays off. I would recommend it highly.

I would turn up the IOR on the reflection and refraction layer for the wine glasses to 1.8. I would also add a little color to the glass by making the refraction color a very light gray. Then set the IOR for glass on the cabinet to something lower like 1.2.

he says he checked for duplicate faces, but I agree with you - it looks completely like z-fighting. Could be that some component got copied twice - it's happened to me before... You can confirm by altering your viewpoint and see if the pattern changes. With z-fighting it does - as it's view dependent.

doesn't VRay for MAx use newer core? EDIT: also, yeah, if you could post a side-by-side comparison (with rendertimes), that would be awesome.

@adeeb88 said: i get error message of the activation for v-ray Thanks ADEEB [image: ?_task=mail&_action=get&_uid=2781&_mbox=INBOX&_part=2] Can't see your image. Seems to be linked to your mailbox. When you post you can upload images to the forum, see the "Upload attachment" tab under the textbox. As for whatever error it is, when it's an activation issue you need to contact ChaosGroup Support. They can help you out with that.

Cheers again

Here is the trick// http://www.sketchupvrayresources.blogspot.com/2012/02/tutorial-2-point-perspective-rendering.html

it's a bug. Happens to everyone. The only solution currently is to open the files with vray disabled in SU and do your copy and pasting then.

gabbyquan, did you find a solution? if I save in .EXR, open in photoshop, adjust the gamma correction with Exposure, looks quite ok

@pololo said: but, it will be awesome to have a shadow matte in vray sketchup. There are some Shadow channels - you even see one of them in the screenshot. Don't remember what the various do though.
