only show effect of the blending mode of one layer, not layer-content itself
on Jul 2, 2019 at 9:25:55 am

Hey,
I have a simple question, but somehow not easy to google, so here we go:

I have a PNG-Layer "Masks_Windows" with B/W-Shapes in my example, which should effect the layer below "2019..." with the blending mode Exclusion. But I don't want to see the actual white shapes of "Masks_Windows", I only want to see the effect onto the layer below (the nice negative effect)



Seems very simple, in other Software I know how to, but in AE I got a bit lost.

Help would be highly appreciated

Hi. I think what you want to use is a "Track Matte".
Turn your blending mode to normal.
On the Fabric layer, next to Modes/ "Normal" box, is the Track Matte box, twirl it open and select Luma Matte.

Is that what you wanted?

Hey Greg,
thanks for your answer! I tied to so, but then the negativ-effect of my blending mode disappears and the factory-layer is only visible in the windows.
Is there anyway to keep the negative-effect of 'Masks_Windows' onto 'Fabrik' without seeing the actual white shapes of the 'Mask_Windows' layer?

Here's what happens when I use the track-matte

Sorry for the tripple-posting, but I attached the wrong image

Hi Konstantin. I now understand.
Precompose a copy of your layers - Fabrik above Masks. Set Masks Track Matte to Alpha (the white windows should now wipe on)
In your main composition have two layers - the Precomposition above Fabrik. Set the Precomposition's mode to Exclusion.
That should do it(?).
