To Many Mattes cancel each other... Maybe?

Participant ,

I have a comp generated from an Ai file (a graph with about 25 elements). The bars on this graph have 2 sets. one illustrates a total number and the other is a much smaller percentage of that total number. These to sets of 6 bars overlay with the smaller bar on top. 

I had no issue importing and the layers look as expected.


1.  I pre-comp'ed each set of bars (2 precomps total at this point).  

2.  Inside of the precomp with the large bars i created an animated custom shape that moves from Left to Right while rising. Then i precom'ed that to add effects later. 

 

At this point i have 2 comps inside of a comp. One comp contans the large bars and the other contains the animated shape.

 

3. I added a set matte to the bars comp, and targeted the animated shape layer and inverted the matte. This worked as expected. 

I repeated that for the Smaller bars comp.

The only difference is hat i used a solid as my revealing matte. 
All worked as expected within the comp. However, in side of the FULL comp where these 2 elements are the main part of the smaller bars disapear totaly.

Are the Mattes not playing nice together?

A flow chart would be helpful. I don't see any Track Mattes on any of the layers in any of your screenshots. I don't know how you are generating mattes. I don't see any animated properties on any layers. I am not sure that I can be of much help without a lot better understanding of how you are using the mattes.

 

When I have something complicated like you are describing I try and either create animated reveals using a track matte for a single layer or using Set Matte on a bunch of layers. If you apply a matte to a layer it should create transparency on that layer and no other layer. You can have multiple instances of Set Matte set to invert matte, all pointing to different source layers that may or may not be turned on (visible) to poke multiple holes in a single layer or if you add Invert/Invert Alpha at the bottom, you can reveal different parts of the layer. Soething like this:

It would really help if I knew what was going on in the comp. Here's the flow chart for this example:

Agree with Rick. Your screenshots tell us nothing because you cropped them and they also don't show any native matting being used anywhere nor any effects such as Set Matte. It's really impossible to make sense of what you are actually doing. Some full screen screenshots of all the comps with the relevant properties exposed would certainly help.

I'm still not exactly clear what you are doing. As per your flow chart you are not using any effective matting or at least not in a place where it would matter and do something. If you really want them to have any relevance they would have to be much higher upstream. The most obvious flaw in your chart is that your wave motion is actually only linked to one of your comps, so maybe you need to duplicate it and insert it into the otehr comp. I also can't see the solid you mentioned anywhere, so yes, something is most definitely not set up the right way.

Same issue here also. 

the problem is the letter R. 
In this comp i had a PSD with about 8 elements. The letter 'R' is broken into 3 pieces. (vertical line, curved top and the foot). I use shape layers to create paths the would revel each part like a write-on. I use 2 keyframes to trim the path. 

in the main comp i can see the verticle line and the curve animate on but not the foot of the R. Inside of the pre-comp the foot animates as expected but in the main comp NO. it doesnt even show at all unless i DE-invert the matte or remover the set matte.

the set matte on the foot apears in the flow to be connected to 2 things but i can not see this in any of the modifiers or how it would be set that way.

This is the letter with one mate showing. The verticle line is in mid animation and foot of the R is just sitting there with no effect from the animated matte.

Is there a second way to do this?

Also in the main comp you will see another instance of the foot R and the Foot Mat. This was my first attempt to use the set matte to reveal the foot of the R. It does not work either.
