Custom Bone Colours
Ghost (Pose) Drawing
New Mode: On Keyframes
This new drawmode for ghosts only draws ghosts which occur on keyframes within a frame range. It is useful for getting an idea of where the poses are in 3d-space with regard to other poses.
It is worth noting that this ghosting method can be slower (sometimes significantly) compared to the other ghosting methods due to the searches performed for keyframes.
New Option: Sel
This option, found beside the 'GStep' field, means that only the selected bones will be ghosted. It helps to see how a specific part moves as a whole, instead of just what one part of it does.
Bone Paths
There is now clearer grouping between tools for path 'cache' creation, and path display in the 'Armature Visualisation' panel. This helps present the two stages of working with paths more clearly.
Improvements in Visualisation
[Nice screenshot of path + bone (before + after showing) goes here]
Paths are now drawn in a more colourful way than before:
- Parts of paths that are before the current frame are drawn with black/grey lines
- Parts of paths that are around the current frame are drawn with a green line
- Parts of paths that are after the current frame are drawn with a light-blue line
- Paths of selected bones draw brighter than those of unselected bones
The display of markers on the path has been improved as well. In particular, the marking of keyframes
