Add a method of naming a sequence of frames somewhere in the Blender UI. These will become the named AnimationRecordings in Unity.

e.g.
{
name :"Cube Unfold",
start :36,
end :59,
}

After a little time working with this code I decided it's just too poor a baseline, but given I've learned everything involved in making blender UIs, tools for blender and unity etc... I've rewritten the project entirely it works a lot more reliably and has a sensible data file format which is descriptive.

I'll be publishing io_export_shape_keys and shape keys for unity shortly.

It's annoying to have to export multiple objects which exist on the same animation timeline. It would be preferable to iterate over selected objects, or all objects in the scene. A checkbox should be included in the export window for "Selected Objects"

The file format used is cumbersome and seems to leave out vital data such as scales for the shape keys. Replacing the file format with a textual format which describes both the shapekeys and the animations would solve this problem. It would also reduce the amount of code used for parsing to almost nothing and clean up some poor type encoding (strings where floats should be).

Extra things we want to encode include scales, image files and start shapes and allowing multiple animations in a single data file, thereby reducing significantly the complexity of setup. This would mean that the diffMaps and animationRecordings would be automatically generated when loading the JSON file.

Figure out a way of pre-building the diffMaps into an output format of some kind with the scales data so we can test that we've got the correct scales computed.

Scales as stored in blender are wildly incorrect. It appears to be 17.5% of the value written to the file.

Remove the poor code which doesn't check if an object has materials first.

Presently only getting a partial output from the export.

Playback on the Unity side doesn't match the animation that's being exported. I have a feeling this is related to "scale" for each of the diffmaps. I need to learn more about how the old script was calculating these to ensure that I get the correct output result.

Add methods for

• setFrame(frame )
• setShapeKey(string keyname, float level)

Rename diffMap to Shape Key generally, improves the cross talk, a shape-key-map or shape-key-texture would be preferred language.

Make unnecessary API exposure private.
Remove dead code in the blender plugin & unity script

Currently it appears to strip materials from objects. The original code has a backup strategy but it's poor and doesn't appear to work as intended.

Line 187 onwards used to target color1 through color4, the crack happy hack was just to target 'color' but the documentation is unclear about proper update process.
