Don't know what I did

 I would take note of which USB ports you are using, this likely is playing a role. (some USB C ports offer more features than others)

publishing an X offset of the input in the projector actor

 I believe this is working in this configuration, unless I miss understand. 

My input is 3000px by 1080px In IzzyMap, 

I move my rect to the far left and select each right side corner, and enter 1920 (this creates my 1920x1080 output selection) 

I right click the Rect slice, and publish the Offset X 

Then on the Projector, I can move my view from the left edge to the right edge. (-1 thru 1)

I would also suggest going the GLSL Shader route. LLMs can do pretty well if you feed them the contents of Tutorial 3 here and the guts of one of the existing TT GLSL shaders as an example, so that they can understand the formatting requirements.

I'm trying to avoid too many internal scene triggers, so that each cue is its own scene. Is there an alternative for this?

 The alternative I would suggest is not to break something like this into multiple Scenes. With a Sequential Trigger actor used to start your cues in sequence, it's easy to do what you're describing in a single Scene.

@michel Thanks Michel for the quick and helpful reply ~ will try.
