I was working on a camera projection thing, and I came across this weird problem. The plane I was projecting on had a white shape running through it, when I changed the rotation of the plane, it moved the shape, but messed up everything else. Anyone know how to fix this?
I see a lot in your screenshot that tells me you have not done much homework on the Track Camera tool. Here are just a few of the problems:
This is the standard Track Camera workflow:
Switch to the Motion Tracking workspace to easily access all of the tools you need
Trim the footage layer's in and out points so you are only tracking the part of the shot that needs to be tracked
Make sure the footage layer is 2D and at the all of the Transform properties are at their default values
Run Track Camera and in most cases select Detailed Analysis to improve the track
Delete any tracking markers that are on objects in the scene that are moving - like the actor walking through your shot
Select a surface to use as the Origin and Ground plane if there is a suitable horizontal surface in your shot and the shot did not solve as a camera pan
Set the origin and ground plane for the shot if you can and use the same points to add a solid and a camera
Verify you have a good solution for the camera by carefully observing the movement of the reference solid - adding a grid can be a big help
When the track is good, use tracking markers to set up additional reference solids (nulls are hard to see) and attach them to the fixed geometry in the scene and make sure that they track properly and they are sticking to the surfaces
When you have sufficient solid layers attached to the fixed geometry in your scene you can set up multiple camera views and start adding other 3D layers to the scene and positioning them using the reference solids as guides
To complete the scene add lights and fine-tune color balance and any other elements you may need to make the composite believable
Turn off the reference solids so they will not render - but keep them so you can go back and do some editing (pro-tip: make all reference solids you added using the Track Camera tool Guide Layers when you add them so they don't end up in the final render by accident)
Here's a screenshot halfway through setting up a shot where I need to put a crashed truck behind this old building and add an actor to the front porch that we will shoot on green screen, and some additional 3D animated objects in the foreground. Note the reference layers. A track matte created from a shape layer for the edge of the building only needed a few keyframes. This Comp is ready to Export to C4D so I'll have some geometry that matches my scene. I also used the parent all the 3D layers to a 3D null at 0,0,0, then move the null to Comp Center to normalize the 3D working space. This is how you use Camera Tracking. I should do an in-depth tutorial. Oh wait, this shot is for my upcoming advanced compositing and visual effects workshop. (yeah, that was a cheap plug)
The production notes and the camera path will give me a reference I can use to shoot the actor so the perspective matches when we shoot that shot. The actor will be a simple 2D layer on top of everything and a simple animated track matte to put the actor behind the post on the screen left part of the front porch.
I hope this helps. There is nothing wrong with your project but workflow.
After rotation it's a pretty good guess that you've also moved it away from its solved position, ie, you've moved it such that it is no longer part of the scene but in its own world space.
Instead of moving/rotating it as is, try moving the Anchor Point to a location where a rotational move will not disaffect the layer's position relative to its original solved position. If this is not possible, look at the solved track points again and this time, identify solved points that are where you want them to be, without having to commit to a rotation.
