delicate drum
This is a long shot but i've been struggling with bone transformations in Godot as it works differently than most 3d applications. Godot seems to assume world-space for everything and this is often undesirable for hierarchy-based items like a rig skeleton.
Currently, I want the ability to specify euler angle rotations relative to a bone's rest rotation. IE: Vector3(0.5, 1.0, 1.5) would rotate the x, y, and z axis by those values. The issue is that Godot's built-in functions seem to rotate things in ways I'm not expecting. In experiments I have this code that rotates the second joint 45 degrees:
var Skeleton = get_scene().find_child("Skeleton3D")
var Bone = Skeleton.find_bone("Bone_(1)")
var RestPos = Skeleton.get_bone_rest(Bone)
var SetRot = RestPos.rotated(RestPos.basis.z, deg_to_rad(45))
Skeleton.set_bone_pose(Bone, SetRot)
Applied to a test object, the rotation looks like this (see image). The pivot is correct, but the bone should not be moved positionally if its using the rest pose as a basis.
Is there an easier way to apply rotations explicitly in gdscript? I really need these rotations to be relative to the bone's rest position/rotation so that I can read external data to apply animations properly.
As a side note, I also have the option of exporting the full transformation data from external applications (Blender, Maya, etc), but I would like to avoid that as it needlessly bloats the data when all I want are rotations.
