Separate Layers that have blend modes AE3
on Apr 24, 2011 at 10:54:19 pm

After Effects CS3

I am attempting to separate two layers that each have a Multiply blend mode on them, because they are each on a White Solid Layer.

From the beginning:
Comp Red Blob, and Comp Blue Blob are created. They are identical in creation, however cannot be on the same comp so they do not interfere with one another. Here are the steps in which I created each blob comp.

Two circle layers were created and blurred to nearly completely ghosted. A White Solid was then created, and placed under the circles layers. Then, an adjustment layer on the very top layer with a curves adjustment. The curves are set to the highest possible contrast, bringing the blurred circles into sharp edged circles. When the circles are animated moving close together, they begin to merge similar to a water droplet merging with another water droplet. This is only visible because of the white solid layer beneath.

When I import both blob comps onto the main comp, they come in with the white layer, naturally. So I used the Multiply blend mode to get rid of the white, and keep my blob shapes. However, I want the two blob shapes to overlap, without blending into one another.

Is there a way to separate the two layers blend modes from affecting each other? - Keeping in mind that they both must have the White solid in their respective comp. to maintain their water droplet effect.

Thank you for your responses!

Ian

If I understand correctly you want to separate the coloured blobs from their respective backgrounds.

Forget the blend modes (nod to Walter "transfer modes").

The best way to do this is to create a matte based on the colour values in the layer.

One way is to apply a linear colour key to the layer and key out the white. This should reveal the blobs alone.

[Brian Charles] "Forget the blend modes (nod to Walter "transfer modes")."

I'd like to thank Brian, Michael, and the rest of the community for their support during this difficult time of transition for me. :)

Hey everyone,
i got the same problem, but i need the "multiply" blending mode...

is there an easy way of separating layers from each other so that only the top layer has a "multiply"blending on my background picture?

You'll need to create a matte for the second layer (as Brian mentioned above). Then you'll be free to use Multiply for the top layer.

If you can post a couple screenshots, it might help us suggest other ways to address your problem.

I'd either mask it if it's static, or make a procedural matte if it's not. You could use possibly use either the threshold effect or the levels effect (possibly with some smoothing like media or minimax) to create a luma matte, or possibly a chroma key effect to create an inverse alpha matte.
