As you all may or may not know, in MA 3 you can use the camera views to help arrange elements in layouts, however this only works for the primary fixture instances, it does not work for subfixture instances.
As a result, I built this plugin. It takes the layout view built by the camera arrangement and replaces each element with an array of subfixture elements that you provide via a template. I thought it was quite handy to have in my programming, so I figured I'd share it with all of you lovely people
Code and usage instructions are on the Github page. https://github.com/gabe927/gma3-subfixture-layout
Please let me know if there's ways to improve the code or if any issues show up.
