problem with matching ai generated layer in after effect using 3d layer for camera tracker

New Here ,
Jun 11, 2023 Jun 11, 2023

can someone help me? when importing ai generated layer from Photoshop i get it in the right position in after effects but when I'm using the 3d layer for camera tracking and converting the generated ai to the 3d layer it will get messed up and won't fit any matter how im try to scale it and change rotation. is there a way to fix this?

 

I have attached 2 images 1 with where the ai generated building is in right position and one where it failed. 

 

please can some one help me? is there a plugin for that sp I can track the camera and get imported 3d layers to fit where i want?

When you use Camera Tracker, make sure you set an Origin and Ground Plane, then create the Camera and a Solid using the same target. This will zero out the position of the first solid and give you an easier time attaching other layers to the solid. Then you can add any other solids. I use solids so I can see them and verify they track properly. I also set the Solids as Guide layers. 

 

You can then add your Photoshop layers to the comp, make them 3D, then Shift + Parent them to the appropriate solid to snap them to the same location as the solid. If the Solid sticks to the surface it is supposed to stick to, then the Photoshop layer will also stick. You can then use the Rotation and Scale properties (not Orientation) to line up the Photoshop layers with the proper surfaces.

 

I'm not sure what the Photoshop layer you are having problems with looks like, but any layer you attach to a surface using a camera tracker should have no perspective. Camera Tracker only generates a flat plane. If you don't select co-planar tracking points, any added layer will be a flat plane between at least 3 of the track points you selected or an average of the selected points, but it will still be a flat plane. 

 

If your Photoshop layer has perspective, you need another approach. Mocha AE and some version of Corner Pin Tracking will probably provide a better solution to your problem. The most efficient workflow depends entirely on the shot and the assets you want to add to the frame. 

 

If you have more screenshots, please drag them to the reply field and expand them so we can see them in your post. The Attach button works well for shared project files, but sharing images is a pain.

Your footage is terrible for tracking. If it was synthesized it may have spatial inconsistencies that throw offf any 3D tracker and of course the big flare doesn't help, either. Whatever you plan on doing there will require a conventional perspective tracking approach where none of this comes into play even.
