I think Alchemist and Spriter 2 are the same thing.
I know, I've seen the feature comparison between Spriter 2 and Alchemist on their website before they removed it. It looked like basic features are being removed from Spriter 2 to entice people that already paid for the software a decade ago to buy it again. Even in the free version of Spriter, you get basic IK, but you don't get that in Spriter 2 unless you upgrade to Alchemist. This is how they repay early supporters.
lucid So you have nothing to say? No reasonable explanation?
