do you think you could upload the file so we can try to reproduce it in a nightly build?

I know nothing about VRay, but have you checked to see if you have any reversed faces and if you have a material applied to your front face?

see discussion here: http://sketchucation.com/forums/viewtopic.php?f=322%26amp;t=56468 best to wait for the vray 2.0 service release.

thank you everyone for all your valauble help..

Thanks for all the comments, your feedback is most appreciated, I guess I was looking for some control of the reflection, I'll try the back face transparency and see how I get on.

@mandanagmp said: Hello, I have been researching this issue for a few days now, and have tried several solutions. When I render my Sketchup model with Vray, only the windows are rendered. I have placed everything on the 0 Layer, un-grouped everything, and copied and pasted the model into a new Sketchup file. The last technique works, but only once or twice, after which, it simply renders only the sky, and NONE of the model. I hope someone has another solution! Thank you- Sketchup 8 Vray 2.0 Windows 7 If you're using vray 2.0, you should see a progress window come up. Are there any errors that show up there? Look specifically if there are materials that are failing to load.

I just realized that I had not posted the webinar replay link.

To map a texture like that to a sphere you'll need to use a plugin such as Whaat's UVTools. http://sketchucation.com/forums/viewtopic.php?t=23725

yes, DR stability is improved in 2.0 in all cases.

Thanks, it turns out I didn't have animation on but Vray still looks to see if the "Include Frame Number" checkbox is checked. mild annoyance -Brodie [image: Xodh_frame.png]

did you make sure that in your window glass material, you have the option "Can be Overridden" disabled?

this shouldn't be an issue in 2.0. If anyone is still using the outdated 1.6 BETA version, please upgrade to the latest release. 1.6 was a beta only, was buggy, and was not ready for commercial use.

You can always learn how to create your own materials. I hardly ever load vismat files, especially from random websites. Most of those files were probably create in 1.05.30 or earlier!

You can't change where we write temporary textures to, without breaking everything. 1.6 doesn't exist. That was a beta version, you should be on 2.0 now.

You could try placing a rectangular light just outside the window facing in and setting it to be invisible.

What does this checkbox do? -Brodie [image: vdWK_batch.png]

@chopsuey said: Hola! I'm making some interior (bathroom) renderings with multiple mirrors. The problem is that the reflected image in the mirrors always turns a bit purple. Here I found out, that the problem is my setting for "Energy preservation mode". I need to switch it from "RGB" to "Monochrome" >> http://help.chaosgroup.com/vray/help/150SP1/examples_material.htm BUT - I can't find where to switch this option in Vray for sketchup Help please Thomas looks like this may have to do with refraction. Do you have a plane of glass in front of your mirror? If so - either remove the refraction layer, or change to fog color to pure white. Hadn't heard of the energy preservation mode before

Great, thanks for the tip! -Brodie

NAT is not an issue once you're connected to a VPN, because you're connected to the internal network that lives behind the NAT at that point (unless you have some sort of special setup)

you could also hack the VRayPlugins.xml file to modify this setting in 1.49.01... but that's a little dangerous BACK THE FILE UP, PRIOR TO MODIFICATION!!! <parameter handler="default" label="Use color texture as transparency" listType="none" name="use_color_tex_alpha_as_transparency" type="bool"> <value> false </value> <handlerinfo> <tooltip> Enable this if you wish to use the alpha from the color texture for transparency </tooltip> </handlerinfo> </parameter> just have to change the false to true
