If you make the particular solid a 3d layer, the particles will not appear in the anaglyph 3d space separately, they will appear flat at the position of the 3d solid’s layer that you applied particular to. The solid is now in the anaglyph space. Ask josh.

There is a way to use your other layers to matte out the stuff you don’t want to see… you have to duplicate all the mask layer stuff, precomp it if it is more than one layer and use this as a garbage matte for the paper layer. You alpha matte it with the the paper, now it will only blend in the areas that the garbage matte is cutting out… Basically your are using your whole animation to matte out your texture, and then compositng the texture back on it. I hope this makes sense, I don’t know how your setup is exactly. I am not sure if this is the best way but i’ve used it before. You might get a slight edge on your result but you can adjust the garbage matte to fix it.

You could use the older technique of luma keying, just put your clip in a precomp. Add a white solid and use the luma matte mode. it’s under the alpha matte modes in the little pulldown in the timeline window. (I think they are called the track mattes) This will pull a clean luma key, and when you put the precomp in your main comp you will see that it now has an alpha channel.
I say older technique because it’s one of the ways video tape worked with keyable video. Just think as your clip as a separated alpha channel.

Actually I think Aaron used a 2d adjustment layer (without effects on it obviously) to break the 3d.

I think there is a tutorial by Aaron R. about breaking the 3d space. If you insert a 2d layer in between two 3d layers, it changes the way after effects composites them, forcing them to act like 2d layers would, but still exist in 3d space. So you can make something further back in z space appear on top by separating your 3d layers with a 2d layer. I just tried it now with a solid scaled to 0 (so it stays invisible, turning off the solid didn’t work.) I don’t know what kind of seperator Aarron R. used… it might have been a tip inside another tutorial…
If you just take one 3d layer on put move it’s layer order to the top in the timeline, it will not act like a 2d layer would and lay on top, because it is acting as it should be, further back in z space is behind everything else closer in z space. If you want one 3d layer to appear to be in front of another 3d layer, you need to use the above technique to trick After Effects into doing it.
