Why does "Always Rasterized" PDF Vector Map become pixelated when Pre-composed???

[ninose11]

I just ran into a big problem after I pre-composed my vector PDF map even though all layers have "always rasterize" checked in the original comp.

I don't understand because my composition window is NOT more than 100% zoomed in . 

Here's the original comp:

The problem is that when I pre-compose, my map becomes pixelated when I zoom in. If I click "always rasterize" for the pre-comp, it disables being able to zoom in on it in 3D.

You must also turn on Continuously Rasterize/Collapse Transformations in the Nested comp (pre-comp). In your second screenshot, the switch is just to the right of the Shy button on Layer 4.

Hi Rick, thank you very much for your help. The problem is that if I turn on "always rasterize" for the pre-comp on Layer 4, the pre-comp is then no longer 3D thereby disabling the cameras and nulls as well:
 

This is what happens when I do that:

When you Continuously Rasterize a nested comp, the active camera of the main comp and any lights in the main comp are used. It does not look like any of the layers in the nested comp (layer 4) are 3D. Changing all of the layers to 3D should solve the problem.

Hi Rick, the problem is that the original comp needs to remain 2D because I have animated track mattes representing invasions. If I make all my layers 3D in the original composition, the invasion animation no longer works:

You should be able to get everything lined up and working in your Pre-comp. Collapse transformations in the pre-comp. Make that layer 3D, then pre-compose it again and name it something like "3D animated map".  Make sure you move all attributes to the new comp. Then try collapsing transformations again.

I do this kind of thing all the time. 3D track mattes work. You may have to separate all the layers by 1 pixel in Z space. It's all about properly organizing your compositions.

Hi Rick thank you very much for your help. When you say "collapse transformations in the precomp" do you mean that the "Invasion 1" and "Invasion 2" animated track mattes should be themselves precomposed within the initial composition? Like this?

The only problem is that once I do that, and then rasterize the precomped layer in the 3d composition, my invasion layers are no longer in the same position:

Rasterizing the precomped map causes my precomped invasion layers (from the precomped map) to shift way out of place...
