Yeah, do as Devin suggests and try the light subdivs first. The other thing is that you are 1.48 which is a pretty outdated version. Not sure if this would change things, but I would consider the upgrade to 2.0

Thanks! I will check them out.

I've had similar issues with creating vray proxys. I've exported the vrmesh from 3ds max, imported into sketchup via vray, then apply textures to the proper materials. Then I save that SU file as "tree 1.skp" or whatever. I usually have no problem opening this file later and rendering - the textures/materials are still showing up. However, when I'm working in another scene and import that same SU file with the proxy, the textures will not consistently render. When I sample the materials of the proxy, the texture shows up in the SU material editor for about a second, then it disappears, it seems like the vray material editor which has lost the link to the texture overwrites the SU material - so it defaults to a solid color. Not sure that helps, I could be doing something wrong but in the end I need to place proxies without re texturing all the time. Chuck

Sorry being an idiot, had accidentally deleted the source files. Doh!!!

he has been beta testing through the entire development process, so I would assume it's a 2.0 render.

Were you testing 1.6? If so, I would think that because 2.0 is really the final release of 1.6 beta, you have used up the 30 days already. You might be able to contact chaos and ask for an extension to fully test 2.0 I would think.

oooh! Is mesh light coming

2.0 was released today, I think we may have already addressed this issue

Are the faces reversed?

hi, I'm rendering some elevations with phys cam and field of view with 1degrees. I have hdri map in backgrund, but the scale of the images is very big??? Does anyone know what a can do to fix that?

yup, it's just a port of the VRayMtl from V-Ray for 3D Studio Max

we use the same control for all external file controls. So in some cases it's handy, in others, it's not.

i didn't use 2.0 for some reasons

I agree, check to see if there are duplicate objects fighting for the same space. It is also good practice to model with front faces out. I don't think having a back face out would cause this, but it is good modeling practice to eliminate these back faces.

Yep, it is. 1.49.01 used to purge out any saved material settings when you loaded a material from the SU material library. It also purged all of your material settings on a copy and paste and importing a component. Those days are over! 2.0 keeps these settings. So, when you create a material you like, just drag a copy of it from your material browser in SketchUp into a V-Ray material folder. That way, you have all your favorites ready to go. I have a library with glass, a few plastics, grass with bump, concrete, etc. Things I use all the time. Another tip is make a library with a generic gray diffuse and a reflection layer at various glossiness levels and save those as a starting point for making plastics. For example, I have a library that has Plastic 90, Plastic 80, Plastic 70, etc. Then all I have to do is apply this from my library to my model and adjust the diffuse color right in SketchUp and I already have my reflection layer setup. NOTE - that any maps such as reflection or bumps are not saved along with the SKM file, so you need to have a network library location that keeps them organized and in a central location.

That looks awesome! Thanks for your help, I'm relatively new to V-Ray for SU, so this will help with my experimenting I googled how to make lights in Corel and found a pretty decent tutorial, so all smiles for the near future!

that error message is happening because SketchUp has used up all available memory that it is allowed to use. All versions of SketchUp prior to 2015 have been 32bit applications, which are limited to 4gb of memory. SketchUp 2015 is available as 64bit, and is capable of using a great deal more memory. I would suggest visiting our help page about 64bit workflow: http://docs.chaosgroup.com/display/VRAY2SKETCHUP/64+Bit+Workflow I would also suggest upgrading to the latest version of both SketchUp and V-Ray for SketchUp, being able to utilize more than 4gb of ram while rendering is quite a big deal, especially for our users out there that have 16gb+ of ram in their workstations.

To me this looks like jpg artifacts. Outputting as a png file should see that 'rainbow' shading disappear. David
