I have resolved the issue. In testing I was just playing the sequence on the Pi that will control the Panels. Today I linked the main show Pi to the Pi running the Panels and the sequence ran as it should on the Panels.

I am trying to set up a P10 panel matrix (5x6 panels) for the first time. I have the matrix working, but when i try to set up a sequence with a singing face the sequence plays on the bottom two rows only so you just get the top portion of the face. (This also seems to be the case with other effects as well.) However, I set up a test version that only configures the Panel matrix and those singing faces work as expected (as well as other effects). So it would appear that the problem has something to do with the configuration for my complete set of models in Xlights and is not an issue with the P10 matrix per se.
I am using Xlights v. 2019.43 64bit, FPP v. 3.2, with a Raspberry Pi 3B with a PiHat. I am attaching the Xlights setup page and layout page for the non-working system and the test version that does work. I am including the FPP Output Channel setup (all 90 universes are the same). I am also including the Xlights Check Sequence output.
