Bind pose clarification

I’d just like some clarification on where the bind pose is defined - I assume via inverseBindMatrices in a skin? I’m just looking for clarification on where the rest pose vs normal pose is defined

I’m not completely familiar with the terms here, and trying to look up more information I’m finding answers that define “rest pose” and “bind pose” as being the same, or not the same, depending on the source… I guess the short answer is that the inverseBindMatrices should be used, and there is no distinct concept of a bind pose.

Apologies for linking to a paywall here, but the first few paragraphs of the chapter are visible without purchasing this book and might provide what you need?
