TEST 3 - IGNORE INDIRECT LIGHTING ON PLANTS WITH LOWERED GI

Part 3 of my test. As we saw in the last 2 videos, increasing the GI boost from -1.0 to 1.0 helped a lot, but at the expense of double the rendering time (ack). I'm not a fan of doubling render times unless needed...

For both of those videos, IILOP was left unchecked.

For this test, I've lowered the GI back to -1.0, but have IILOP checked ON now. We'll see what this does to the look of the animation....

What I was surprised to find was I actually had about equal rendering time as with IILOP turned off as I did on. However, the flicker was very evident.

At this point, I've decided never to use GI in an animation until Vue gets the GI speed up a bit. The hit you take is just too rough.
