I think I may have a solution. Don't mess with the transparency in the refraction layer, unless you have more than one refraction layer. Just leave it black

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.

thank you everyone for all your valauble help..

@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.

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?

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

@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

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!

Great, thanks for the tip! -Brodie

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

I assume your scene is a 2D scene, coming from a photomatch? You can try 'Camera>Parallel Projection', then 'Camera>Perspective', then create a new scene. You should end up with a 3D scene with the same point of view. Vray should then handle it fine.

whoops! I missed that version number... 1.48.93? Any reason you're not using at least 1.49.01? It was a free upgrade. You might end up saving enough time using the wrapper material in to justify the upgrade cost to 2.0. Depends on the learning curve required to do this all in post, and time it takes to actually get the result you want. Andy- I don't think there's really any other way around it, excluding what has already been discussed, aside from doing two separate render passes. One with just the model, and the other with the ground plane. That's how I would have done it back in the day.

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 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

http://help.chaosgroup.com/vray/help/150SP1/tools_ply2vrmesh.htm I also have a tutorial on the Chaos Forums where I use the converter to make meshes for SketchUp.

There are a host of things you can do. Try using Catmull Rom AA filter and increase your Image sampler settings - Adaptive DMC Min 2 Max 12 Clr thresh .003 Increase your render size all of these things will increase render times dramatically.

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

@khodan said: @dkendig said: looks like you're using DR, and something isn't transferring to the DR node properly. This should be resolved in our 2.0 release afaik. Have you tried a demo? What do you mean with a demo? we have a demo or trial version of our 2.0 version available on our website. I was making the assumption that you were not using VfS 2.0. Glad to hear you resolved the issue though

If you are unable to upload the file then there must be something wrong with it. It looks like it is only 10 faces, and the textures are simple it should be a tiny file size. If you have huge amounts of stuff hiding in the file it can cause problems. Purge everything from the file and try to upload it again.
