You can take a look in to my answer → It would be the easiest way to integrate it to your project with as less affords possible.
Also I am not sure why people are so ANTI C++ → it is way faster and cleaner than blueprints.
My project are about 90% C++ My blueprints are mostly inherit C++ classes to make visual adjustments and set some parameters/properties like textures/meshes etc…
I can not imagine how would I do it all in BPs even if we assume that BPs had no Limitations → it is an eye sore to manage Complex logic there - and a pain in the butt to maintain it.
