Question

Glow effects in 3D Space is glowing over the edges of the layer frame

Hello, sorry if I'm using that channel not correctly.
I have trouble with After effects:

I created a 3D space with a lot of (star picture) layers. classic flight through.
On some picture-based layers I want to add a glow effect. Which works niceley. But for some reason the glow effect is ignoring the frame of the layer and shines out of it. Which normally is great. But in my case i need a clear cut off out of the frame. (Because there are other effects waiting which must not be affected)

I'm an aspiring beginner. Means still learning the magic how alpha masks work in AE. Here my two possibly solution-leading questions:

1) How can I set something somewhere, that no effect is leaving the frame of a picture layer (without trying to mask something and bring that in sync with flying pictures)?

2) can I enlarge the layer around the picture (to give over-shining glow effects enough space to spread out) or must a picture be seen as a fixed layer structure (since layer adjustments for size etc. are greyed out when clicking on the picture)?

In the attached pic you can the the shadow on the red background which comes from the glow effect.

I found out a lot already, but this is really freaking me out now and I would be very happy about any help!

Best
Daniel

You have several adjustment layers on top of your others and pretty clearly those cause the artifacts. You need to restructure your project and pre-compose stuff in a sensible way.

    Hej Mylenium, first, thanks for your answer!

    ok, I ve forgotten to mention: please don't at my session itself. it's an experimental playground where I'm trying to prepare the final session. 
    To make it more clear I have attached another pic where you see that its not cause by my chaos session. just a clear one picture layer and and just one generative - and trouble causing - effect: glow. To make the issue more visible I have added the CC Light Ray effect to show that there seem to be an invisible extra layer - like a buffer zone for FXs.

    Solition: precompose the pic and put glow effect on picture in precomposition. 

    But: I will have 60 pictures in my session. Partyl very complex ones. And I would be happy to keep things as minimal alias CPU-saving as possible. 
    So the question is: Does anone know a way to switch off that "buffer layer" or how to keep (glow) effects inside the picture frame without cause extra precompositions?

    even when I mask the Picture layer, the glow is acting beyond frame and for some reason the turbulent noise effect(which i put on "multiply" is interacting outside of the frame with the overglowing effect. So apperently all FX work outside of the picture as well. Which would be nice if the multiply blend mode would work outside the frame as well (as it does inside perfectly)
