I've got some fire mov files that I'd like to use in my piece, but how can I simulate the light it creates on all the other elements in my composition?
The simple solution would be to create a layer with Fractal Noise on top, Mask it out to match the contours more or less, colorize it with Tint or Tritone and use Add Blending mode. Then animate the evolution and offset of the noise and add further adjustments as needed. The hard way would obviously be to duplicate your layers and use elaborate masking and coloring to fake the lighting per edge/ face. If this are 3D layers, of course using a wiggle()expression on a light's intensity property would also work to a degree.
I think the "wiggle" is gonna work, but now I can't get the fire to look like it's inside the dumpster. I thought sandwiching the fire layer between two dumpster layers would be a start. I'm assuming I need to do some masking (I know a little Photoshop, but it doesn't 100% translate to AE). This is what I've got right now:
You need to separate the dumpster into two parts. Put the foreground part in front of the flames, the background part behind. Then you need to add a copy of the flames that's blurred with probably the screen blend mode to give the appearance of firelight.
I hope this helps.
That's what I thought I was doing with the two dumpster layers, but no matter where I place them the fire doesn't sandwich. If I change the Z axis (forward/backward?) the fire either moves in front of the dumpster or behind no matter what layer it's on.
I know I'm probably stating the obvious but the front dumpster layer doesn't appear to turned on. And, Just to be sure I'm understanding this correctly, you did seperate the back part of the dumpster from the front correct? Also, I'm not sure what you mean by this...
If I change the Z axis (forward/backward?) the fire either moves in front of the dumpster or behind no matter what layer it's on.
The fire should move in front or behind the dumpster if you change the z axis, but it shouldn't matter what layer it's on in 3D space. The layer order isn't important it only matters where you place the objects.
D'oh!! You're right, that layer was turned off.
I guess I thought layer order matters like it does in Photoshop.
I cut out the front panel on one of the dumpsters, and I think I've got the fire looking like it's inside. Now I'm looking for cropping the edges of the fire so it doesn't spill beyond the dumpster.
I really appreciate all the advice.
