#Incorrect Skeletal Animation Results

As you can see in the attached image, when translation and rotation values are applied to joint local transformations, the result becomes completely deformed.

Any advice or help is welcome.

I have deduced that the calculation of global transformations and subsequently the joint matrix works correctly and thus the error most certainly occurs at load–time.

More specifically, the issue seems to be with loading rotations.

#

I don't have time to write the rest so I'll continue this later sorry

Alright

#

first question: does GLTF have any odd rules when loading from a vec4 buffer?

#

e.g. empty buffer memory between elements

Issues like that are best investigated by using a test model that's simple enough to examine directly

Just make one

#

It can literally be like one cube with a bone

hexed yoke
#

okay

jade hull
#

Or a triangle with a single moving vertex

#

Yeah

#

Moc's idea is good too, even easier to debug

hexed yoke
#

okay

#

but

#

how do you make a single triangle in blender 😭

hexed yoke
#

Okay

#

Single triangle test worked

#

most likely an inheritance problem

#

that I think is occuring at loadtime

#

actually inheritance seems to work just fine

#

but it's showing 3 bones instead of 2 which is alarming
