mikes8500 Posted June 10, 2009 Share Posted June 10, 2009 What are the optimal Indirect Illumination (GI) settings to do a sun study? I've got the part down about linking the vray sun to the max daylight system. Thanx Mike Link to comment Share on other sites More sharing options...
BrianKitts Posted June 10, 2009 Share Posted June 10, 2009 Use the animation IRR presets so that you can blend your irradiance map across multiple frames. I prefer to keep LightCache for secondary, but I do not precalc it. Link to comment Share on other sites More sharing options...
mikes8500 Posted June 10, 2009 Author Share Posted June 10, 2009 Hi Brian Thanks for the reply. Can you give me a little more detail, when you say you use the animation IRR presets,do you mean the built in presets right under the irradiance map header, or the Mode presets. I tried using the mode preset Animation (prepass) every 10th frame, to try and pre-calc. Seems like it created an autosave .vrmap file for each frame. Do I hit save when it is finished and use that file when I switch the mode to Animation (rendering)? Or do I select the first autosave file. How exactly do you blend your irradiance map across multiple frames? Mike Link to comment Share on other sites More sharing options...
gfriedman Posted March 26, 2010 Share Posted March 26, 2010 does anyone have any good tut's on doing a sun study animation? I too have figured out the linking of the sun system to the vray sun but having never done a vray animation I don't know what settings I need to be thinking of...

Well, don´t have any tut´s, but you don´t need to link Vraysun to anythig. Just animate the parameters for day and time in the Modify panel. (Provided you setup a Daylight system previously, with Vraysun chosen as sunlight and Vraysky accepted to enviroment, and no Skylight). This is the automatic way to link Vraysun to timelapse renders. The trick is to optimize GI calcs.I'm just now trying Brians tip, but still testing... Link to comment Share on other sites More sharing options...
