Cad64 Posted June 17, 2010 Share Posted June 17, 2010 I don't use Vray, so I can't really say what might be causing this, but if you Google this problem you will find many possible solutions. Quote Link to comment Share on other sites More sharing options...
minks Posted June 17, 2010 Share Posted June 17, 2010 well physical camera can be pain if your not familiar with basics of real life photography (aperature, f-stop etc). also bare in mind that vray lights behave diferentlly when using P-camera. im guessing you placed a camera in front of the glass, so you should check your refraction subbdivision for the glass, (take it up to 20 or so), post your gi settings (light cashe and iridiance map settings). and if your getting good resaults with normal camera i see no reason to bother with physical camera, it does give you more freedom but as said if your not verry good with real life photography it just adds more complications to your rendering setup. cheers Quote Link to comment Share on other sites More sharing options...
Exelweb Posted June 23, 2010 Share Posted June 23, 2010 OMG your work is very good. Keep it up. You have done a tremendous job. I do not much about this but i think you can heal the dots in photoshop i guess. Quote Link to comment Share on other sites More sharing options...
Cad64 Posted June 23, 2010 Share Posted June 23, 2010 I do not much about this but i think you can heal the dots in photoshop i guess. No, it's a problem with the render settings. Fixing this image in Photoshop would take ages. Quote Link to comment Share on other sites More sharing options...

The problem was solved, you were right the problem was with the render settings. check "sub pixel mapping" on the color mapping tab. (Note: when I turn sub-pixel mapping on only , I got rid of light dots) If anyone wants more information open this link http://forums.cgarchitect.com/28616-white-dots-my-vray-rendering-help.html V-Ray for 3ds Max official help index http://www.spot3d.com/ Tnak you.

I think that made glass with wrong reflection and refraction setting like (IOR , color selector I want to learn how to create vray glass well . I found tutorials (V-RAY MATERIAL SETTINGS , Rendering Glass and Liquid) *.pdf by author Wouter Wynen These tutorials can be found : under (Chaos Group) http://commerce.vismasters.com/download/view/type/?dtid=2 (*.pdf , zip) or http://designmeet.com/index2.php?option=com_docman&task=doc_view&gid=20&Itemid=44 http://st.free-lance.ru/users/Zelen/upload/f_496fa34f84716.pdf I agree with you that physical camera can be pain if we do not know basics of real life photography.
