3d layer acts as if it were parented

[madalinp69590848]

Hi there! 

For some reason, the moment I tick the 3d box on the "BG" layer, it behaves as if it were Parented to the Tracker Camera. 

I've attached a couple of screenshots of "BG" in 3D and without. 

Any suggestions would be much appreciated.

You have a misunderstanding here. It's acting just as it should. Apparently your camera is solved in such a way that the default 3D positions are a bit weird and turning your space nebula into a 3D layer therefore will also make it look wrongly oriented. You simply need to adjust its position in 3D space.

Hi Mylenium, 

Many thanks for your support! I guess a better question would be: "How do I get it to behave like in this tutorial, at 06:15".

You have a 3D Camera tracker in your comp, probably with keyframes. Your layer is not parented but in a 3D comp where the camera has movement, so the layer react to the camera position and point of interest, so this is what it should happen. No problem here, it is the correct behaviour.

Aside from this being a pretty terrible tutorial in the first place you are missing the track matte and pre-composing part. I suggest you re-watch the tutorial.

This tutorial is a perfect example of a poorly explained recipe that won't work with all shots. The problem I see in your screenshot is that you have not parented the background layer to the camera track solid. You don't actually want to parent the 3D BG layer to the solid, you want to hold down the shift key and then parent the 3D BG layer to the Track Solid so. that it snaps into position.

The other. amateur parts of the tutorial include:

• Inefficient way of masking the screen in preparation for 3D tracking using AE's Camera Tracker
• Failing to check the accuracy and possibly try selecting detailed analysis to make sure the camera track is accurate
• Failing to establish an origin and ground plane
• Not explaining or using the most efficient rotation controls to line up the horizontal and vertical edges of the Track solid
• Scaling the Track solid is a bad idea, resizing it is a good idea
• Not creating a duplicate of the Track solid to use as the source for a Pre-comp used as the background layer

The tutorial has about 42,000 views, but it isn't that good and the creator does not share a single explanation for any of the steps in the workflow. All it is is a recipe.

If holding down the shift key and then parenting the 3D background layer doesn't fix your problem let us know. Maybe one of us can point you to a better tutorial.

Thanks so much Rick, holding down Shift and parenting actually worked! I'm over the moon! 😁 Thank you!
