Problem solved! Thanks TedVitale_CG Whit tiff is ok

Thank you both. Already have your plugin installed TIG, very useful plugin- did not realise you could specify not to purge materials. iminy-billy-bob - Thank you, applying the material, makes perfect sense now.

You can turn off the RGB and Alpha channel and that saves you a little bit of time. But V-Ray still has to calculate the light passes in order to get those channels, so you wont save yourself a lot of time. In my tests its one or two seconds per minute. On larger renders over the course of hours this might be helpful, but I doubt it.

You need to update to the latest Service release, 2.00.24261. http://www.chaosgroup.com/en/2/downloads.html?s=v-ray-sketchup

Maybe your color mapping ? I don't have 3Dsmax with me right now, but it might be something like this: Render Setup > Vray > Color mapping > Mode : Color mapping and Gamma.

Hiya I think you need to synchronize materials under Plugins>VRay>Debugging>Force sync for all materials. I have this set to a shortcut because it's buried in sub-menus Cheers Corey

Hi Huisno1, This is an old fixed bug. Please upgrade to the latest Service Release 2.00.24261.

Thank you Adam, I appreciate your help and very fast replay. Work as it need. Thanks again

So a few tips; don't change your dynamic memory limits to such high numbers. Sketchup can only access up to 3.8/3.9 gigs of ram (3800/3900mb) before it crashes. Its still a 32 bit program, and we have to work inside those 32 bits. The dynamic memory limit is measured in megabytes not gigabytes or kilobytes. So when you use large numbers, like what you're putting into your dynamic memory limit, you're not actually helping your rendering speeds. If you set it to 0 its automatic and V-Ray will figure it out on its own. By default its set to 1024, so its a little slower, not noticeable in small renders, but more stable with larger ones. I'd suggest changing it to 2048, or 3072 if you would like to access more memory. The next thing I would suggest you try doing is using the 64-bit workflow to prevent large, complex scenes from running out of memory. When running this method, set your dynamic memory limit to 0. See the attached PDF Document for more information. The 64-bit work flow, along with other helpful tutorials can be found on help.chaosgroup.com/. 64-BitWorkflow.pdf

Have you also installed the latest version of Fredo's "Lib" which is required by most of his tools, and clearly indicated in the tools' guidance notes and their 'Dependencies'... It is available from the PluginStore http://sketchucation.com/pluginstore?pln=LibFredo6 or via the PluginsDialog - simple Search for "LibFredo". Try that, restart SketchUp to effect the changes... THEN get back in touch if it's still broken...

There are a bunch of tutorials on the website: http://help.chaosgroup.com/vray/help/sketchup/150PB/tutorials.htm This topic is covered by our interior rendering tutorial. Take a look, there's a lot of really helpful tutorials there. Also, let me know if there are specific tutorials you would like me to put together!

@ohichyo said: Another thing that I couldn't find out yet is how to make the reflection in the wooden floor smoother. Is there any setting in the reflection layer (or any other) I can change to make that happen? Yes, you should reduce the "glossiness" value for highlight and reflection to something like 0.75 or so. Then you need to up the reflections subdivisions to something like 24 or 36 to keep it smooth (otherwise at lower values it gets grainy)

@valerostudio said: You have USE COLOR AS TRANSPARENCY ticked on. Turn that off. I would also load a glass vismat from the Chaos site, something with reflection and refraction. That suggestion is useful.

Cheers for this... attached is how its looking so far [image: puf2_SCENE2.jpg]

@jiminy-billy-bob said: @coreymurray said: (double sided tick box in option in mat editor) This tick box only means that the material will be applied to both sides of the polygons. A Vray2sided Mtl is a really special material. It allows you to have different materials between the front and back sides of your polygons, and blend these two materials together (and the light they receive) depending on a grey value (or map). This allows you to mimic translucency for very thin objects (one face only): Paper, leaves, curtains, etc. https://www.google.fr/webhp?#q=vray%202sided Thanks for the explanation Jiminy - that's a really powerful technique.

1.6 was a beta and that is over now. We are now on 2.0 and this was a bug that was fixed.

Hi, Adam: I like this.

You need to subdivide you're sphere more to give V-Ray something smoother to render. I'd Suggest manually making your sphere using circles with more sides (48-64) or using a plugin like Artisan to subdivide and smooth your surface.
