alfienoakes Posted October 27, 2005 Share Posted October 27, 2005 I am fairly new to Vray, but have been using Viz for a while now. I have been reading that vray is a fast render engine etc.. but when I set my scene up, it takes along time to render.. Now I do have allot of reflective materials in the scene, some glossy etc.. but I only have 2 light sources in there.. GI and 1 direct light as the sun.. This image took about 5 hours to render at 800x600, and thats after knocking back all the relfections. I am sure it is something to do with the reflections, but I really need to get the render times down. We set up two machines to render two images each, with over 14 hours to spare, at 1024 x 768, and when I got in to work, all they had done was the attached..! I had to really work in Pshop to get these to the client. I have posted them in finished work if anyone wants a look..! Any help tips etc.. greatly received..

chuck Posted October 27, 2005 Share Posted October 27, 2005 it sounds like it's your glossy reflections. lower the quality (subdivisions) from 50 to 3 and see what happens. if you have area shadows turned on, that will add a lot of time too... what are your system specs? chuck Link to comment Share on other sites More sharing options...
kippu Posted October 27, 2005 Share Posted October 27, 2005 try switching off the glass at the top and calculate the irrmap and then put it back on when rendering ... that could be one reason why it takes so long ... do post the settings .... vray is fast with the right settings Link to comment Share on other sites More sharing options...
alfienoakes Posted October 27, 2005 Author Share Posted October 27, 2005 Thanks.. These are my Vray free settings, as the attached image. You are right about the glossy settings, sub divisions.. all set to 50..! I have allot of materials that are using reflections as well.. Kippu.. I don't think I can do anything with IR settings, as I noly have free..? I could be wrong.. Thanks Andy Link to comment Share on other sites More sharing options...
chuck Posted October 27, 2005 Share Posted October 27, 2005 your lighting numbers look fine...it really looks like it's coming down to glossy reflections and area shadows. chuck Link to comment Share on other sites More sharing options...
alfienoakes Posted October 27, 2005 Author Share Posted October 27, 2005 That does ring true.. as soon as I started adding reflections in.. glossy.. it all went pear shaped..! I will make sure that I turn the sub-divisions down, and give that a go.. There is probably about 7 - 10 materials, all with glossy reflections in there..all at 50..!
