# Spline IK Bake Pose

How can the Blender User get the desired visual results for Bake below?

• Legend for image above.
• The letter A is next to a selected Armature which henceforth, for brevity, will be named [A].

• The letter B is next to a selected Armature which henceforth, for brevity, will be named [B].

• [A] has the indicated Spline IK Constraint. It is active.
• [B] is the result is the result of copying [A] and then a Bake was performed. The Bake parameters are highlighted in blue in the info window.
• The User expects [A] and [B] to look identical. [B] with no necessary constraints. Simply Baked Transforms for each bone.

• The results show a recognizable correlation between [A] and [B]. Yet [A] and [B] are not identical as a User Visual.

Bake Parameters in text.

bpy.ops.nla.bake(frame_start=1, frame_end=5, clear_constraints=True, bake_types={'POSE'})


The User can get better results not using some features of the Spline IK Constraint. With the check boxes [Y Stretch] and [Use Curve Radius] not selected [A] and [B] look more similar. Still noticeable differences are present. Clear Scale improves situation.

Still not a 100% satisfactory context.

• I'm still having a hard time understanding your question. Part seams like there is a missing image, you keep referencing [A] and [B] but that is not shown. The last paragraph makes it sound like something is for addon, so is this whole thing needed for scripting? – David Oct 7 '17 at 14:45
