bone (smart) to control color fills over time

Post by zoesan »

I can't find the video demonstration of how to control a color fill using a bone, not sure which smart bone to use: Regular: Morph or Smart: basically to dial the bone from transparent to color fill. The timeline no longer displays the fill tool once out of frame zero and can this be used on scatter brush, its a blood splat effect

SB to control fill - one way to do this:

bone layer with, e.g., bone B1
> vector layer with a shape

with the bone layer active create a new action for B1 - set B1 to, say 0 deg at frame 1 and 100 deg at frame 256 with linear interp.

still in the action, select the vector layer and then select the shape and make sure the action timeline is on frame 1.
click on the fill swatch in the styles window and that opens up the colour picker. Choose the colour you want and set alpha to zero.

move to frame 256 - click on the fill swatch in the styles window to open up the colour picker. Choose the colour you want and set alpha to 255.
set linear interp on the fill colour keys.

bone angle 0 => 0 alpha; bone angle 100 => 100% alpha; and all points in between.

====

another way for a layer with multiple shapes with maybe different fill colours - e.g. splatter

bone layer - masking - hide all
> vector 1 with multiple shapes of different colours - mask this layer
> vector 2 with a shape that covers the area where you want to fade out the vector 1 shapes - add to mask, keep invisible

use the above approach to vary the opacity of the vector 2 shape.

===

or have more than one shape in vector 2 and in the SB action stagger the alpha changes for the shapes ...

==

and there'll be countless other ways depending on exactly what you want to achieve…
