[Simple Idea] Disable inheritance from parent

warmanw

Give us an option to disable inheritance rotation and scale only from direct parent, this way we should not create another transform constraint to make everything else above parent to continue affecting rotation and scale.

This would help me on a daily basis

Spinebot

Disabling inheritance of rotation and scale from only the direct parent while allowing inheritance from other ancestors is a complex feature to implement due to the intertwined nature of rotation, scale, and shear in the transformation matrix. Spine currently provides options to disable inheritance of these properties, but they apply to the entire hierarchy above the bone, not just the direct parent. This is because the transformation matrix combines these properties in a way that makes it difficult to selectively disable them without causing instability or unexpected behavior. As a workaround, you can use transform constraints to achieve similar effects by controlling which bones inherit transformations.

Spinebot's suggestion of using Transform Constraints seems spot on.

This might be slightly off-topic, but I personally find disabling inheritance more confusing than using transform constraints. Unless you select the bone, it's not immediately obvious what the inheritance option is set to. I often find myself pausing to think, 'Why is this bone moving like this?', then checking its properties and finally realising, 'Oh, right.' It feels like a bit of extra hassle. On the other hand, transform constraints display an icon next to the bone name. This makes it obvious when a bone is behaving unusually — you can quickly tell that it's due to a constraint. Plus, they offer greater flexibility. Therefore, recommending transform constraints generally makes perfect sense.
