@stefanq said: John, follow this link http://www.lithonia.com/photometrics.aspx and download all photometric data files. As you can see, there are some categories for different type of applications, indoor, outdoor,commercial, etc. Use that free viewer and browse only the category of ies files that you need. The viewer is quite fast, it renders the cone of light in a sec. Cheers, Stefan thanks and about ies lights , do you ever change the power or the size of IES lights? i'm trying to adjust lights in one scene of a showroom, and they are giving a burnout kind of look. [i'll post a view of it soon]. if i lower the intensity to 100,000, the scene becomes dark, if i increase the intensity to 300,000, the scene looks like lighting of fireballs in the dark. i'm not able to get the lighting as seen in various photos like this apart from IES should a rectangular be also used? a rectangular light interferes with my abstract ceiling pattern .

@valerostudio said: It's buggy but I dont think 1.05.30 is a better product. Just the ambient occlusion, IES files, and transparent PNGs are enough to convince me to deal with the bugs. As for the debug menu, you have to go to Plugins - VRay - Help - Debugging. There are a few options in there. Beware that this will reset all materials in your file to defaults. Yea - 1.05.30 is more stable - but the features of 1.49.01 is so good that I can't ignore it. Fortunately a new beta should start soon.

Hi Rich, Yep, I'm running the latest Sketchup v8 and I uninstalled Vray and installed it again. I've removed Maxwell Render in previous attempts when installing Vray and it makes no difference. I have a paid license of Maxwell Render this time and I'm hesitant to uninstall it!! There is obviously something on my laptop that doesn't agree with Vray. And I'm no closer to solving this issue. Vray support team were uselss. Thanks Anita

it works when i put some boxes and lights. I'm guessing it may the 1. the file size; 2. overlaping surfaces in the model. i decided to do it all over again, since none of the mentioned solutions worked for me. shame tho, if it's about the file size, SU developers should deal with that ty for your help, though

this bug is still there? i'm using 1.49.01 there is still a slight difference. [image: SSBP_31.jpg]

@valerostudio said: Dont forget to set your subdivs high on that refraction glossiness (30 or more). Render times will be a beast but the results are worth it. the subdivs setting will control how smooth the frosted glass looks, the higher the number the smoother it looks (but at significant cost in render times)

Welcome! You could try adding a studio setup, like explained here: http://nomeradona.blogspot.com/2011/10/lighting-with-vray-sketchup-definitive.html Or you can make a room with furniture and context, etc. and light the room as you would normally. Andy

@john2 said: you can also write ur version of vray, windows version in ur signature. so that you don't have to write it everytime. just like i've done But now you're using Trimble SketchUp ...

@fuzzion said: @john2 said: i'm trying to create pebbles. just a jpg file and a bump map produces tiny ugly mountains in the render. can anyone help? Over 3400 free vfsu mats. But if you use them and like the mats, pls donate. He also sells you the entire collection on a dvd for cheap $. http://luzindirecta.luxisessentia.com/ I used cobblestone, road1 and gravel mats found on his site. Excellent quality , no low res limitations. [attachment=0:p5z5wutc]<!-- ia0 -->Sample_roads.jpg<!-- ia0 -->[/attachment:p5z5wutc] yeah i'm aware of it.

i encountered this problem once and if i remember right, it was due to the fact only the billboard tree image on front face casted shadows, not the backface. so try to turn your model monocrome and make sure the front face of the billboard is facing the lightsource..

Again me. I've solved the problem. I just installed new version of V-ray: 1.49.01 ( I had 1.48... something) And now I can import materials from the same vismat library I used to use. Now I have: Windows 7 home (64bit), sketchup 8 pro and V-ray: 1.49.01) This set works fine. Thanks for anwsers.

that looks very nice. I wonder if playing with the parallel/ perpendicular slots in the fresnel settings (adding a flake map) might do the trick with adding flakes. I'm curious to see how this compares with the Chaosgroup vismats - like thomthom, this is what I've been using as a starting point. Andy

Thanks guys. i finally got my IES light working

did you save your file, close completely out of sketchup (no other windows of sketchup open) Then open back up and try rendering again? Sometimes the vfs cache gets corrupted and you need to close out and try again.

Reduce the Ambient Occlusion under Indirect Illumination.

it is a nice reminder not to give the glass any thickness, when you're doing an interior shot. however i would still opt for giving the glass thickness, when you're doing a shot from exterior (double faded reflections in the windows).

Does it say VRay Processing on the lower left of the SU Window? You might have to wait. Parsing on a large file could take a while. If VRay processing starts and then disappears, then you might have a texture issue. Are you textures high resolution?

I may be wrong but I think its in the frame buffer but it is not fully implemented into the SU plug-in. Ask at the Chaos forums to be sure.
