I have created a tutorial that shows you how to do exactly what you want:

The way I did it for my Texture Pack Promo video is by using an obscuration layer.
Create your mask on a solid layer, then precompose that layer and move attributes to precomp, so the mask is inside the precomp and not applied to it.
Then turn off the visibility of the precomp, and use it as an obscuration layer in particular.
This method works great with 3d layers as well if you need to create a mask that the particles stream around (particles pass in front of, but not behind)
Here is a link to the video, right at 28 seconds is where the particles spray down and get obscured.

This happens when two layers are too close together in 3D space. If that door doesn’t move, you can precompose it with the wall texture. If you need to have it separate, you will have to move it further away from the wall until it doesn’t show the glitch.
This is caused by an imperfect algorithm for calculating depth of field of 2 objects that share the same plane, and are too close to each other.

In my Butterfly Bliss Menu Template, I achieved wings flapping by using a much more advanced method (expressions), but it yields very nice results.
I started by creating 3 separate layers in photoshop: 2 wings and the body. Imported those into After Effects and made them into 3D layers. You then create a Null object named ‘Butterfly Controller’, and apply a few expression controls: A Slider control named ‘Wing Rotation Amplitude’ with a default value of 80, another Slider control named ‘Wing Speed’ with a default value of 6.73, and an Angle control named ‘Wing Rotation’ with an expression applied to the value:
amplitude = effect(“Wing Rotation Amplitude”)(“Slider”)/2;
frequency = effect(“Wing Speed”)(“Slider”);
amplitude*Math.sin(time*frequency)+amplitude;You can then select the Anchor point of each wing, and using the pan behind tool, move the anchor point to the edge of the body. Now parent each wing to the body, and parent the body to the Butterfly Controller (the Null object). Then apply an expression to the Y Rotation of the Right Wing:
thisComp.layer(“Butterfly Controller”).effect(“Wing Rotation”)(“Angle”);
Then Apply a similar expression to the Y Rotation of the left wing (notice the *-1):
thisComp.layer(“Butterfly Controller”).effect(“Wing Rotation”)(“Angle”)*-1;
Now you can use just the Null object to control the movements. The position of the null dictates where the butterfly travels (you can also parent a particle generator to the null and have pixie dust trailing behind it!). The rotation amplitude sets how wide the wings flap. The Wing speed adjusts how fast the wings flap. You should enable the graph view while changing this value since modifying the value of a sin function can create strange anomalies.
Here are the results:

Encore’s preview of Blu-ray projects is not very good. Problems such as you are describing happen frequently, especially while previewing the actual menus. These issues are almost always in the preview only, and not the final build. Try burning to a BD-RE disc to test it out, or better yet, build an image and use a software blu-ray player to test.

I’ve experienced glitches before like you are describing. I’m pretty sure it was just a bug with the preview, and the actual burned disc did not exhibit the problem. Otherwise, it could be an incorrect aspect ratio setting somewhere.

If you can, separate the colors of the button highlight into different layers. For instance, all the orange in the tv will be on a layer named ‘(=1)Orange Highlight’, all the black will be on a layer named ‘(=2)Black Highlight’, and all the gray will be on a layer named ‘(=3)Gray Highlight. Then go into the ‘Edit Menu Color Set’in Encore, create a new color set, and adjust the colors to your liking.

You may need to use the Set Matte effect, or precompose the keyed subjects so that Particular does not “see” your key. If it’s not a perfect key, you might have some issues.

Even if you have a burner and media that supports 16x speeds, you will most likely have lots of errors on anything that is burned faster than 4x. Even though redundancy is built into the data on the disc, with lots of errors you will make the player have to do a lot more seeking to get all the data it needs… and sometimes it will not be able to get all of it and will skip.

Are you working in 16bit mode? Towards the bottom of the project window it will say 8bit, 16bit or 32bit. Alt click on it to cycle through the different modes.
