mariome Posted October 17, 2012 Share Posted October 17, 2012 One quick question, can i calculate irradiance map and LC without depth of field in vray physical camera then save those maps, load them and then turn on depth of field in camera and render final image? Is there a problem with quality or any kind of flickering? Thank you guys! Link to comment Share on other sites More sharing options...
BrianKitts Posted October 17, 2012 Share Posted October 17, 2012 (edited) yes you could, shouldn't cause any problems. but oddly you may find that if you calc with DOF on, your irradiance pass will be faster! It's very scene dependent, in the global setting turn off the render image, and test a region of your image with DOF on and off to check the calc time variance. Think of it this way.... if DOF is blurring and smoothing your image, it's less detail for the image sampler to crunch on so it calcs through it faster. where as in a sharp scene every detail is shown and the image sampler will be less adaptive crunching every little detail thus longer calc times.

mariome Posted October 17, 2012 Author Share Posted October 17, 2012 Wow seems logic, i will make some tests about rendering times, anyway you answered my question, thanks! Link to comment Share on other sites More sharing options...
