Professionally in Unreal 5. Hate it with a passion. Not only is the engine a shared state leaking piece of s*it but the language(s) that come with it make the whole mess even worse.
In my free time I worked with Bevy which is really promising in my opinion. I hope their editor will be as amazing as the rest of the framework.
Recently I also tried Fyrox. It is nice, probably usable for some smaller things, but damn it feels a lot like Unreal again with going a OO-like paradigm. Of course little to no memory-safety issues it being developed in Rust as well (+ a runtime borrow checker they implemented on top to check on shared writes to Resources, Nodes, etc.), but compared to ECS it feels terribly clunky.
you could put some other foil on the outside that is cut to the silhouette of a bird of prey. and there exist bird models that work as scarcrows that you could setup somewhere close to the window. i saw them in standing and hanging variations
