NOVEMBER 14, 2001 Playing with Fire in Boris FX 6
Both of these filters have been built in more or less realistic mode, but that's not necessary. The Fire filter is an elaborate organic particle system, with controls to color it any way that you want. Likwise, Burnt Film is a luma key applied to a gradient wipe with colors applied to the edges. Make the colors more extreme, and animate the gradient WITHOUT animating the "Burn Amount," and you can have a quick lava lamp sort of effect. The point is that reality need not apply any limitations on you as an artist. That's a pretty cool feature all by itself, actually. [an error occurred while processing this directive] Last but not least, I'm going to show you why I applied the Fire filter to the Face of the V1 layer by turning on the layer's drop shadow. You'll see that the shadow is applied to the inside of the map, so that as the layer progressively burns away, the shadow moves with it. That's because we've applied the filter UPSTREAM. Boris renders from the bottom up, so the changes to the map layer are calculated before the shadow is. 
Applying the Fire filter with its nested Burnt Film mask to the layer itself would have been DOWNSTREAM from the shadow, which you wouldn't have been able to see unless you moved the entire layer. It may seem confusing to you, but it's really not once you start to play with it. Indeed, once you know that this feature is here, you can start to play around with it and very easily create effects that would be quite challenging otherwise.
