Any experience and on the Source 2 Filmmaker included with Half Life game Alyx, M'lord? If not what are your thoughts on it at least?
Nope. Pretty certain I've already addressed this, but by all accounts I've heard, it makes Source Filmmaker seem stable and complete.
Among other things, it apparently has no scripting support whatsoever - a massive drawback for me, since I use scripts extensively. To say nothing of the fact you have to buy Half-Life Alyx in order to access it. For someone who doesn't have VR nor intends to get it, $60 is a pretty hefty price for the average hobbiest to pay to an unfinished program. Not really a concern for me, but it is a point worth considering nevertheless.
