Thank you for the link sir! I've checked the thread and It appears that I've already tried the solutions stated on the thread..

When you use high quality settings for IM (subdivisions and such) you're starting to loose detail, geometry is "floating". Lower the settings, or, use detail enhancement, or, my favorite one, use AO. Cheers!

Can you soften the edges of an Omni light?

You can use this as a starting point. Just need to make it metal and not plastic Micro_Perforated_Blinds.zip

Go to the videos link that is pinned at the top of these forums, there is a video on pool water and caustics. This will answer all of your questions. I really cannot stress enough, if you watch all of these vids, about 2 hours worth, you will really have a deep understanding of this plug-in.

thanks to all people who answer this question and especially thomthom you are the star thank you so much

I don' think there's any way directly but you should be able to hack something together. This is the first thing I'd try. In 3ds max get the xyz coordinates of both the camera and the target and draw a line from one point to the other. Then export that line as 3ds or dae and import it into SU. Then you should be able to use the Position Camera tool selecting first the camera location end of the line and then the camera target end of the line. Just make sure your lens size (35mm, 55mm, etc.) matches the 3ds max camera as well. -Brodie

You can export geometry from SketchUp. OBJ and 3DS formats seem to be the preferred. I am sure there are plenty of programs that can do baking. V-Ray in SketchUp is not one of them though.

thanks guys I just watched the video and chose default.visopt with a little changes that was recommended in the video and contrast is good now [image: CSPN_1.jpg]

It helps, thanks a lot.

no, that's exactly what i'm not asking (although i have been trying to resolve the issue in another thread, about this time last year.) what i would want is this: i press the render button and if i hit Esc (which should stop the rendering process) or the render finishes, it saves the render (or whatever is in the framebuffer at the moment of cancellation) to a previously specified folder with a name for example autosave0000.png. then when i hit render again (to see how my material changed), the file saved would be autosave0001.png. or it could use a timestamp or i don't know what. hm, but i guess this is a work for a separate script, rather than a matter of settings in vray...

@onzki said: Hi, I bet many have asked or noticed this already- the "reset color" in material editor is greyed out since I installed Vray, now it's hard to revert to original texture after playing around with sliders. Also, my textures was automatically saved and renamed into a temp folder (Chaos Group), not a big deal though.. Have someone figured out how to unlink Vray from overriding my materials control? I appreciate any help, I'm really hoping to get the "reset color" button working again. Thanks a lot! PS: (to Admin) If this is the wrong section, please move it. thanks! This is something you should report to the V-ray for SketchUp developers so they can address it. (Also, it's useful to include V-Ray and SketchUp version when asking questions like this given how different version may act differently.)

The very first version has all sorts of oddities. The newer versions automatically syncs all materials. There is no link or unlink. There was never any unlink though.

Hi guys. Solved the problem... What I did was to copy all my materials/IES etc to my spawner with the exact file path. That solved all problems Then when I tried to use the Vray Material Editor, had several errors and was unable to render. Did the same thing, and testing it out now as I type. Everything looks ok so far, but might need to tweak certain things. Thanks for the feedback guys.

@valerostudio said: But we all agree that fresnel is the best solution for realistic reflections? Yes

Thanks. I will try to upgrade to the latest v-ray version.

I found somewhat of a solution to this, at least what helps for me. Use only rectangular lights, STORE TO IRRADIANCE MAP checked for sure, render with irradiance map as primary engine and use as little omnis and other lights as possible because they cant be stored to irradiance map (no option for that). And output file as .exr vrimage.

Thank's a lot, it's clearer now.

We have recently reinstalled Vray so quite possible it was from the old version... thanks! At least it shouldn't be a problem with future projects. Thanks for your help!
