- By adjusting the density of the Alpha channel.…on the various mats we have,…we've adjusted the brightness of each surface.…Again, the light source is coming from here,…estimating it's brightness…relative to the angle of the light,…but we now need to add a falloff,…the old inverse square law:…things get dimmer as they get…more distant from the light source,…which we can't do with our shapes…because we need a gradient…across all of them uniformly.…So let's give that a go…to add to the photorealistic look of what we're doing.…
So I'll click here and type o…to add a Rodo node right here,…and I'm going to select the Ellipse,…and I'm just going to put up…a little circle thing here.…Switching the selection to Feather Points,…I can now select this guy,…and then…just drag out all the Feather Points…to make myself a nice…radio falloff.…I want it to clip the corners of the…stones out here.…
Alright, so let's see how that looks.…We'll hook the Viewer up to that Rodo node,…check out Alpha channel.…There we go.…So we're going to get a nice falloff here…
First you'll learn how to apply a quick key with Primatte, and enhance the zombie with realistic blood, red eyes, and fangs. Then, turning to the graveyard plate, you'll make a day-for-night color correction and add interactive lighting. Finally, you'll composite the key, plate, and effects and finalize the shot, using color correction and a push in effect. The process is broken down into easy-to-watch five-minute videos, rich in valuable VFX production techniques from compositing guru Steve Wright.
