Are you looking to create animations for a humanoid model? Look no further! The Helsinki XR Center has released their AnimationMaker tool: https://gitlab.com/hxrc_public/hxrc_animationmaker.
The tool was developed as part of their EMIL-funded Gamified Joint Rehabilitation, Analysis and Training project where the team is looking at developing state-of-the-art XR rehabilitation tools (more details can be found here: https://emil-xr.eu/funded-projects/metropolia-uas-gamerat/). They have released a web-based version that functions as a separate module so that you can use it for your own projects!
Please feel free to try this out and share with anyone you think would find this useful!
