  AE adding a solid alters camera

  Posted by Ceri Howe on August 31, 2011 at 11:32 am

  Hello chaps,
  This is my first post so I feel a little daft asking this.

  I’m doing a crash zoom out from a closeup into a wide, cameras in place as are all my assets and everything looks fine.

  However, I want to add a simple black vinette as the top layer and the moment I do that it screws my closeup camera position and changes its start of position.

  Any ideas what I’m doing wrong?

  Thanks for reading.

  If you’ve placed the Solid layer below the Camera or in between any 3D layers it will break the render order of the 3D spaces.

  Place it at the top of the layer stack so that is is layer # 1, of nest the 3D Composition in another Comp and add the vignette there.

  Are you using a wiggle() expression on your camera? If so that could explain the result. wiggle() uses a seed based on the location of the property it is applied to within the composition’s hierarchy, that is to say that a wiggle() expression on one layer or property will return a different result than a wiggle on another layer or property, and if you change the order of the layer/property or add a new layer/property it may change the seed for the returned values of wiggle().

  You can see this effect if you create a new composition with 2 layers (Layer 1 and Layer 2), apply the same wiggle() code to the position properties of the layers, then switch the layer order of the two layers. Notice that the result of the position property on Layer 1 and Layer 2 have switched along with the layer order.

  If you’re not using wiggle() then I apologize for the long winded response 🙂
