Disappearing object after pressing "Aplly Export" from Mocha to AE

Question

I have a strange problem. Namely, I need to paste the inscription on the surface.
The object is in PNG.

I go to MOCHA. There is a path and there are no problems so far.

I'm going back to AE.
I press Create Track Data. Points are shown where they belong.

Export Option -> Corner Pin.

And now it begins.
Layer Export is ... I choose a file in PNG.

All data regarding surface movement is where it should be, only the object disappears somewhere beyond the screen.

I was thinking about what was happening to him. It turns out that I have to add another "transform" option to it and manually move it out of the screen where it is supposed to be.

Anyone know maybe what's going on?

I am not sure I completely follow your workflow. The current workflow for Corner Pin tracking in Mocha:

Add Mocha AE to a layer, click on the MOCHA icon to open Mocha
Add a spline, adjust the surface, track, verify the track is good and the surface behaves properly, and if there are more than layers it is a good idea to name the layers in Mocha
Save and return to AE
Select Create Track Data and choose the appropriate Layer from the popup
Select the proper export option and choose a layer that is the same size as the comp with no Layer/Transform property changes and apply.

I suspect the last step is where the error is. If your layer is not the same size as the comp, which should also be the same size as the footage you track, the layer will fly off into the wrong position.

If your Replacement PNG file is not the same size as the comp use the Transform effect to Fit the PNG file to the comp, pre-compose moving all attributes to the new comp, then export the Mocha Data to the nested comp.

If that does not fix the problem we need screenshots that show all the modified properties of all the layers that are giving you problems.
