Videha Posted July 20, 2005 Share Posted July 20, 2005 there is a tutorial at evermotion on this check it out http://www.evermotion.org/index.php?unfold_exclusive=64&unfold=exclusive Link to comment Share on other sites More sharing options...
Creapix Posted July 21, 2005 Share Posted July 21, 2005 Videha gaves you a good link to start from. Unfortunatly, this tutorial doesn't tell you that the Volumetric lighting will be calculated into the GI Lighting solution, producing very nice effect, but at an incredible cost of render time. Your best bet for now is still to render volumetrics in a separate pass with no GI and composite it (what I usually do) or fake it after. Link to comment Share on other sites More sharing options...
Tommy L Posted July 21, 2005 Author Share Posted July 21, 2005 Do i need to calculate caustics and reflections in the gi solution and does it matter what method of primary and secondary calculation i use? Link to comment Share on other sites More sharing options...
Creapix Posted July 21, 2005 Share Posted July 21, 2005 The caustics and reflections were just because they were using a metal ball to reflect and spread the light on the walls, that's it. So the answer is no Link to comment Share on other sites More sharing options...
