Hey badlogic,
Hope all is well! I'm one of the founders of the company that makes Highrise (https://itunes.apple.com/us/app/highrise-virtual-world/id924589795?mt=8). We recently switched over to using Spine.
I'm trying to figure out how we can optimize our 2d animation workflow, as well as implement the latest animation tech (e.g. meshes) in a framework where we have 1000s of different items. Would you have some time to chat this week about it?
Best
Anton
