Hi, I only speak Spanish. I have a similar problem with "BugSplat" and I have a response to a possible conflict. I deactivated the box "USE HARDWARE ACCELERATION" The "BugSplat" disappeared. the problem may be in the Hardware or drivers. If someone helped this track, just ask. Bye, greetings to all In Spanish/en Español A mi me parece el "BugSplat" aun que sólo cuando se cierra el programa. En un momento desactive la casilla "USAR ACELERADOR DE HARDWARE" y el "BugSplat" desapareció. asi que puede ser problema de compatibilidad del Hardware o de los drivers. ... Si alguien le ayuda esta pista no dude en preguntar cualquier otra cosa. Saludos a todos.

Thanks for your help, I have tried both threads, but with no luck. I also don't have the full Maxwell suite just the plugin which I think would give me much more freedom. I have removed all textures and materials purged the file and then started again with the materials. But still no luck!!! If I render each face individually they look fine, but as soon as I render the whole project I get my stripey legs back. Thanks again, back to the drawing board. Cheers Matt

one quick troubleshooting advice: are you running more than one window of Sketchup? There are some bugs that occur if you have more than one instance of vray running at the same time. Try using only one window of SU and see if the problem goes away.

i find that it's a lot cleaner create a new material, load that texture and properly map it on the geometry rather than import an image and place it onto geometry from file/import etc. create a regular material and always check if it's applyed on the front face.. maybe this will help vray to avoid this strange behaviour.. also, if you need to scale/place the texture in a more effective way than the native "texture position" tool, i suggest to give a look at thrupaint by fredo6, thomthom uv toolkit may be helpful too, as it provides a tool to fit texture to quad faces etc..

This happens to me occasionally when I have changed the colour/transparency of a vismat material and/or I have an imported model with an unrecognised texture. In the first case, I tend to save what I am working on and exit, when I restart it all worls fine. In the latter case, if you are using an imported model, it may be worth removing the textures from this model and re-applying them with either native or vismats. Hope this helps

oh, a bump map... In effect I didn't even think to use it because I tought it was for soft effect... like (for example) orange peel. Ok, I'll try. Or will use a vertical plane to end the edge. Thanks

@thomthom said: But that works by default anyway... Yeah, I didn't know ^^ I saw a tutorial once saying to do it this way, and never questioned it...

That's exactly my experience as well.

@rhed037 said: ...can you pls uplaod any model and ready to render in thea so that i can check what is wrong in my scene and follow your settings tnx Attached please find a very simple model with some spheres... THe render was complete in 16 seconds using the BSD preset... I've used the "Harbor 3" hdri from the HDRI Hub IBL package, which is free to download for registered users... Hope this can help you further...?!? Shadow-catch-test.skp [image: s2Mj_Shadow-catch-test2_16sec.jpg]

@bstjames00 said: Thanks for the help I will try that, but just a note the wall finish is not reflective at all, does that make a difference? Then I would guess it's most likely your light source. Change the shadow subdivisions from (default) 8 to 16 and see if it makes a difference. If you keep increasing the number, but it's still a problem, then try increasing your AA settings.

maybe also more than 30-40 as far as i can see the proper value changes at each renders depending of the lighting conditions.. i suspect that in your case you should raise it a lot because you have a lot of splotches.. keep testing and read soemething about the vray engine.. the link posted by valero is a very good start, look further in that site, it refers to vray for 3dsmax but it works quite the same in vray for sketchup..

@valerostudio said: For the best glass yes best, but pretty much slow..

I'll check them both out, thanks guys.

What format are you using to transfer the model? As cutting edge says - importing SKP format should make the vertices welded. If you use another format it might be that the vertices aren't welded properly.

This link works fine for me.

.mtl will not work with this V-Ray. That's a Max format, which I am sure this model was meant for. Now with that said, I have to say that this is the limitation you will hit every time with SketchUp. It just cant handle geometry like this. Try to import the same file in Max and see how it handles. It's just night and day. SketchUp was never meant to be this kind of program. Some rendering engines allow for proxies which puts a low poly placeholder in SketchUp and then renders out the hi-poly version. V-Ray currently does not have this capability but it is in the works for their next release.

This is a good place to start. http://www.vray.com/vray_for_sketchup/manual/

I think using layer is a buggy with Vray because when i deleted all the layer I have, I can now render my model. Layer has another issue with scenes and Vray. If i turned off a layer on another scene then on the product image the supposed to be turned on layer disappear. I hope chaos group now working on this bugs, and I think what causes much delayed on their product update is because theyre waiting for another sketchup product which fixes especially in counting polygon.
