Hey Hans, I thought your question was interesting so I recorded myself answering it.

I go a little bit of tangent at the start about scene organisation, hope you don’t mind but I had to bring some order to the chaos before I could answer your main question. I promise that I answer your main question after the cleanup! XD
I hope this helps and I am looking forward to the final results. 🙂
