I might be wrong, but I believe you cannot use a linear surface for caustics. Caustics are a concentration of light due to a curved (lens) effect. Robert

Thanks Rich. Will the browser eventually have subd mode (showing the subd basic divisions)? I thought you posted that before. BTW I notice the viewer does not give access to controls once it is full screen or is that just my setup?

Would the same happen for a procedural texture?

@yorik1984 said: I make a small test inspired by correspondence on Skype. Not for holy wars just for fun. I think "Coca" and "Pepsi" are same. How do you think? Great test model! I'm more partial to coke, though.

tankyu @TedVitale_CG it really work

See Attached. Hopefully this helps. Rob [image: xb7e_Capture.JPG]

Neil explains why OpenSubdivs shine https://youtu.be/ENA2FAF_PIc Notice how important Creasing sets(based on angle value, see at 7.20) are. Hope Thomthom will deliver them soon. NB The second part is interesting too

will try that. thanks! also, when i tried to copy to the second model, NOT copy in place, the arrow icon turn to paint bucket icon. I DIDn't select paint bucket icon, and why the paint bucket icon show up??!! did anyone encounter this problem?

You can set it to 0, and V-Ray will use as much ram as is available. Or you can cap it at something like 10,000mb if you want it to not eat all your ram. As a side note, for slightly faster renders you can also turn off "Low Thread Priority" in your Global switches. This will throw everything your computers got (CPU) at the rendering, but you wont be able to do much else with the machine while its rendering like that.

Well, since it seems that nobody is able to give me advise.. so i wasted several hours and watched 4 tutorials (until if found one that gave me some clues..) to find a solution. The "trick" (just in case someone want to know) is to lower the color saturation of the parallel reflection until that effect dissapear. At least thats the only thing i could find to fix it. In the end, i dont get the reflections i would want in some areas (i really dont get vray lol, why is evrything so hard.. xD) but i prefer that instead seeing white dots without reason or "painted" areas with white for no reason.

Fernando did a short video on this a while back: https://www.youtube.com/watch?v=qyidgvF5WlY

This is a demo limitation. Please see the all the demo limitations in the downloads section at http://www.chaosgroup.com.

Have you tried with a vray double sided material? Scene Materials > Create Material > Two Sided Here you can apply a fully different pre-existent material (not just a diffuse map, but with full control) for each different side. Hope it helps. RL.

Can you log this as a bug to me Matt?

I downloaded your script and installed it in 3ds max 2016. I have vray 3.4 I did as in your video and click on the start button and nothing happens.

Please does anyone knows how to render it corectly? Similar problem (without enviroment background was in the post http://sketchucation.com/forums/viewtopic.php?f=322%26amp;t=43350 ) When doesn´t match enviroment background on the screen with render output, I can´t save image with wrong hdri lighting and whole work is useless... I have an idea - could be the problem in enviroment setting? [image: ZJTO_enviro.jpg]

Roo, Did you get any help yet?

@peerman said: You can try changing the UV parameters in the texbitmap material. Changing the tile could do the trick. I usually add another diffuse layer (use a white color in transparency) and add the same bump map to the diffuse slot. This way I can alter or rotate the bump map in the sketchup window using the standard texture tools. Because of the white color in transparency it won't render. Oh, make sure the new diffuse layer is above the diffuse layer you want to render (be it a color or image). Hope this helps! Regards, Thanks, I will try that
