Could I get some tutorial links from youtube or something. What were your reference points? Asking for a friend.

Step 1: Input your footage
Step 2: Put your footage on the timeline
Step 3: Select Effect > Perspective > 3D Camera Thing
Step 4: Wait for it to brown townyze / track n stuff
Step 5: When hovering over the targets(reference points) right click the one you want (the one you want your model / text / whatever) to be on, and click 'Add ______' ('Add Text' for if you are adding text)
Step 6: Select the text in the timeline resources box
Step 7: On the rightmost panel, change the text font / characters / whatever to how you see fit.
Step 7a: Move the text how you see fit with the green /blue / red arrows on the bottom left of the text box by dragging them.
Step 8: In Composition Settings, change 'Classic 3D' to 'Ray tracked 3D'
Step 9: In the timeline resources box, click the tiny triangle/arrow next to your text, and from there click the arrow/triangle next to Geometry options.
Step 10: Change the 'Bevel Style' to Convex(or whatever you see fit)
Step 11: Change any of the Geometry settings as you see fit.
That's basically it, unless you want me to go into rotoscoping, in which case I would rather just talk to the person asking personally, and show them how to do stuff.
