i made a Procedural Walking Animation in upbge. if you want to check it out:https://www.youtube.com/watch?v=7UxuPlKThTg
i can upload the .blend file if any one needs it
How did you do that?
I usually build a mesh then a skeleton to build my animations for my models.
The skeleton approach is slower so I usually bypass UV calculations through a Texture Coordinate node and UV input that hooks into material textures.
i followed this tutorial but i did my own tweaks https://www.youtube.com/watch?v=qvzokeP2uAk&list=LL&index=6&t=391s
