Description
These are three renders I made with 3DsMax5, useing VRay to render, with GI turned on. I tried three settings for irradience map:
1st picture is "Very high" setting. It took over 5 HOURS to render! The image is unedited.
2nd picture was made with "Very Low" setting. It took 3 minutes. Image is NOT SHOWN here. Because it looks exactly like the second image here, wich was rendered with "Low" setting, and took 6 Minutes.
3rd image is the 6minute render, EDITED with Corell Photopaint to clean up the mess the GI made, and some postworked/hand-painted handles and antenna, made under 10 minutes. So it took about 20 minutes max to complete.
So, lesson of the day: undersampling makes just as good images as higher more timeconsumeing settings in case of such a simple image.
BTW, does anyone know why those white/red/blue spots get on the render when useing GI?
THX for viewing.

Those spots look like fotons. I got those in mental ray, not vray but it looks similar. In Mental Ray I got rid of them by increasing the amount of fotons used.

Thanx Rayraz! But those aren't photons in VRay, now i know. I'v been told that the HDRI map used was too big (too many pixels) and that caused the overflow on those spots. Anyway, its still interesting to "see" the difference between the two pics :)

Aye, it's all about the settings. Optimization, and efficiency... Good stuff, I like learning more about this type of thing!
