Version of SketchUp? Version of V-Ray. Sounds like you crashed due to memory. I can't stress how important is to upgrade to 2015 64 bit and the latest version of V-Ray 2.0 Anything else is a waste of your time in my honest opinion.

You need to add a map to your diffuse layer so that V-Ray can get the UVW information to apply the material properly.

Oh I'm using sketchup 2015 on windows.

Ok, thanks I changed the image sampler from adaptative dmc to fixed rate and it works.

Don't know what went wrong, decided to reinstall both sketchup and v-ray. its working fine now.

There are countless ways. You can combine them as a bigger texture natively: 1 - You can shuffle your texture like you're doing right now; 2 - Select all faces and edges (by triple clicking on one of them) for instance; 3 - Then right click on one of the selected faces; 4 - Use soften/smooth; 5 - Soften everything and check the soften coplanar check box; 6 - Now all faces are a surface 7 - Rightclick on the surface (be carefull to have hidden edges turned off) and it selects all faces at the same time 8 - On that context menu choose make unique texture. It will generate a new texture 2048x2048px or 4096x4096px depending on the texture resolution you have set on preferences. There are plugins that shuffle texture position on faces. Try some of the following plugins and then investigate about UV mapping and search for UV in the Sketchucation Store. http://sketchucation.com/pluginstore?pln=ene_texturepositioning_v1.0.2_0 http://sketchucation.com/pluginstore?pln=TextureRandomizer http://sketchucation.com/pluginstore?pln=TIG-TextureTools

@stefanq said: http://sketchucation.com/forums/viewtopic.php?f=322&t=41046 Scroll down until you'll find my posts in that thread. This is the way I do it, and it works for me, but you are at the mercy of your map. The gray values in the map, dictates where and how strong your reflection is happen. Cheers. I tested it out. The bump must make the rendering slower (as the 3ds max tutorial seemed so much quicker and easier) But still, having said that, this seems to work great, thank you so much for your help.

Thanks a lot for the reply! I'll check that

I think I found the reason : I made Component out of Rectangle light so to be able to copy it. When component light is copied it is possible to change settings of all copied components in the same time, not each light separately. I thought changing the light into component might be the reason of grainy light. I checked it: made new rectangular light and then changed it into Component. Before the change it worked perfectly smooth, after it become grainy. What scares me is that when I have 50 lights in sloping ceiling and I want to change the power of them I have to change setting of each light separately. After 1 hour of further working on the project I found that strange: I made rectangular light under cupboard, created Component out of it and duplicated it. The light was not grainy ( the picture below ). I don't understand. [image: 0RsO_26.1.e.jpg]

There is no way about the bobles to ignore them and you have to model them, if you are interested to have a close look. but if you are gonna have a distance look, so there are some tricks, such as reducing the refraction glassiness, etc.

Also make sure that if your glass has thickness, that the glass material is applied to both front and back faces.

This is a great article on the subject. http://bertrand-benoit.com/blog/2015/01/07/the-photographic-look/

Was it modeled and created in 1.49 or 2.0. It is not a supported work flow going between the two products.

V-Ray 1.6 is an early beta version that is no longer supported. Purchase an upgrade to V-Ray 2.0 for support.

Thank you, I will contact them.

I also think it's difficult to have it changing all the time when designing, but I don't use 1001 bits...

Figured it out. Had the wrong V-Ray for the version of SU I'm using

I wonder if this could be achieved with a Toon Material? Edit: I just re-read the original post. You would have to set each material to be translucent. Ignore my toon material reference. Rob

The issue here is that you are trying to make an AO pass the same way they do in Max. The huge difference is the Max workflow uses VRayLight Tex as the base image and we don't have that in VR for SU. 2 Solutions. 1- Just use the AO tick box in your GI settings and it will add the AO automatically (less flexible than having a separate pass.) 2- Remove your ceiling/roof and use pure white in your GI to flood the space with light. You'll have to test this one out. I have asked the Chaos guys to give us the VRayLightTex and the XtraTex pass in order to do AO the Max way, but for now this is what we have.
