I worked on the fog today between the festivities, and I'm disappointed.
Notice how tiled that is. I broke down the 10x10 placeable into 10 layers of 25 emitters, each creating a 2mx2m billboard. The multiple layers creates the foggy blending, and sense of depth. BUT even at 2x2 billboards, the effect is jarring.
At eye level its pretty though.
This particular fog effect will inherit the color of the area lighting and disappears into darkness. Which is achieved with this setting
m_isTinted 1
on the emitter.
I think I'll be going back to 10 emitters each a 10x10 billboard layered one on top of the other, but using the setting
m_isTinted 0
This result creates white fog that will extend into the darkness. But at least it won't look blocky.
