Okey,I see Thank you very much again

On OSX there is an issue that requires you to specify the file extension. Aside from that, the only thing I can think of, is that the path specified either is located in a folder that doesn't exist, or there is an permissions issue preventing you from saving anything there. Choose another path and try again. Use a small scene with just a box or something.

Yup was match photo... I was able to delete the photo, revert to the same camera view and it worked. So weird, it was starting to frustrate me a bit.

but it's either/ or. You can't use both.

@andybot said: You should save out a snippet of your model with just the problem lights and part of the interior volume (delete and purge everything but the lights and some of the space) then submit a bug report to chaosgroup. You could also post it here and those with the beta could look and see if the same issue is happening. Sorry for the delayed response - I had to move on to another project for a few days, but am now back working on lighting again. I realised that this issue is replicated in all of my sketchup files, so have made a miniature file which I will upload with this post. [image: Gdn7_TestSkp.png][image: CCZd_Test.jpg] As you can see, the rectangular light clearly moves back further inside the building between sketchup and final render. If someone could try it for themselves and tell me if this issue repicates for them in either 1.49 or 1.6 that would be fantastic! @valerostudio said: Very strange. I assume the lights are components. This was an issue with the early 1.6 beta that was quickly fixed. Have you thought about trying 1.6 beta? I would love to be using 1.6 Beta already, but unfortunately I missed the registration period, and the Beta is now closed. I am happy to buy 1.6 as soon as it comes out though - so hopefully that will be any day now! Test.skp

Back faces?

@dkendig said: That isn't necessary if you use the purge unused option in the V-Ray material editor What I meant was I use TIG's plugin to purge the model of everything else without losing the VRay materials.

@valerostudio said: There is 2 ways to approach this type of rendering. ... The other way, which makes for a real nice rendering is to place a ceiling plane on your model. Use a SketchUp 2-sided material in V-Ray and make the front face (should be facing into the plan) a white color and make the back face a material that is 100% transparent. Then you want to add some interior lights by using IES or spots and some planar lights at your window openings, and then render the view. Essentially, what happens is that V-Ray renders with no sun flooding into the room from the hole in the ceiling, but keeps it transparent because the face that is facing the camera is 100% clear. Give it a try. http://www.youtube.com/watch?v=qlGVmu-5c-Q

@dkendig said: Render directly to a VRImage to reduce the amount of memory that the VFB uses to display your rendered output (it can use a TON, especially if you're rendering multiple channels) +1 - This will usually solve the problem by itself. You can render to EXR, but if you have channels, you need to have ProEXR installed in Photoshop to see the channels.

@unknownuser said: *Users who purchased V-Ray for SketchUp between April 15th, 2013 and the official release date will be eligible for a free upgrade there ya go. I thought there was an upgrade price as well as a full purchase price, but I guess that just goes to show how much of the marketing/sales info I'm aware of around here.

agree... hope this will be implemented soon..

Thanks Devin That was the problem, your solution worked. ( e.g. Window->Preferences->Extensions dialog. Just check or uncheck V-Ray for SketchUp ) 'SketchUcation Plugins Manager' is a 'plugin' that helps manage 'extensions' and 'plugins'. Initially, I enabled V-Ray through the Window->Preferences->Extensions dialog. Some how, down-the-line, the extension status changed and I didn't realize it. Appreciate your help, Sherwood

Will be very coll if we can define some same configurations in sketchup pure materials by layer for each object.

Well, it would probably be pretty quick to sort out if you posted just that piece of your model. Like valerostudio, I first thought backfaces, but you sounded pretty sure of your modeling, plus the view through the glass doesn't look badly distorted. I'm guessing it could be some issue with the refraction depth being too low value, but it's hard to know without the model to look at.

Thank you very much for your reply! I found it and it's indeed 2.2. Thanks for the advice, too!!!

Valerostudio, Great help (even with the limited info I provided). Bought the referenced HDRI image. Adjusted the gamma, camera, and intensity.......NICE Shadows! Thanks for the help! NH

the 1.6 beta is over, the 2.0 version has been released. Does resetting the light cache get rid of the watermark in the 2.0 demo? The 1.6 beta should be expired and always have a watermark at this point, is it still possible to get rid of the watermark by resetting your light cache now?

Contact Chaos Group for starters. Also, try to uninstall completely - this includes deleting any ASGVIS folders in your ProgramData folder.

@joydeep70 said: With thea render there is a option called z clip. I think that will solve your problem. Thanks for the tip, however this is the VRAY forum not the Thea forum and the last post is over a year old.

I understood. Many thanks valerostudio, I'll try this.
