Thank you. It sounds like this is very much unexplored territory… “here be dragons”.
And yeah… the alpha parameter is one of the many things that is very confusing. Different values gives me results that I can’t really explain. 0.8 vs 0.9 vs 1.0…
It sounds like I’m setting myself up for pain trying to do this.
I’m playing around setting stuff up in Blender to generate synthetic data, but so far not having tremendous amounts of luck getting it to behave.
