I got things a little more sane. My largest problem now is webms related, the bone movement is completely fucked up. It looks like they are rotating around the wrong origin or something. It has to be an exporting issue in blender because i have .dae files that are working just fine, with complex animations.

Usually in blender it's always some shit like

>ah you just have to reset the quaternion armature flip roll top origin, press Alt Shift N, hold W, then right click and click recalculate

Anyone by chance knows what to do?

Check all ur formulas, matrix/quatertnion multiplication orders. Start by animating a mesh with a single bone. Child bones have to inherit from parent bones in a hierarchy. Took me a week to do it all the first time.

It does work with a few other .dae files. It has to be a matter of exporting from Blender. When i create simple rigs myself it works without issues. In webm related, i got the cowboy figure from a tutorial series and created the red things.

It has to be something that happens when you do "advanced" rigs. For the animations in the OP and my first post i created the rigs myself. Possibly when flipping extremities or parenting to non-deformation bones. I suppose i could figure it out exactly with A/B-tests but instead i'll use AssImp instead, a well established library for all of the file parsing and loading.

However to do that i have to migrate from LWJGL 2 to 3 which is a huge pain because they decided to rip out all of the useful bits and replace it with fuck all so i'll have to do that part on my own. >inb4 java

Just use MonoGame and Protogame's animation class. It has no anim blending but it just works. Just use binary FBX which you can cross check in Noesis for sanity.
