I've been asked whether it is possible to create a "Morph Injection" file for props.

Yes you can quite easily, but you need to build the injection file manually.
NOTE: this works in P10/PP2014; I guess it should work in P11 too, but I didn't test in P9!

Proceed as follows:

• Load your prop into an empty scene and create your morphs.
  Save the scene and open it in an editor (preferably PFE by D3D for easier handling, but it can be done in any simple text editor)
• Now create the injection file:
  Open a blank file and write the following code:

{
	version
	{
		number 10
	}
	actor $CURRENT
	{
		channels
		{
			targetGeom Custom_Morph
			{
				name Custom_Morph
				initValue 0
				hidden 0
				enabled 1
				forceLimits 1
				min -100000
				max 100000
				trackingScale 0.02
				keys
				{
					static  0
					k  0  1
					sl  1
					spl
					sm
				}
				interpStyleLocked 0
				indexes 1
				numbDeltas 122
				deltas 
				{
					//list of deltas here 
				}
				blendType 0
			}
		}
	}
	figure
	{
	}
	figure
	{
	}
}
 

NOTE that the actor is referenced as "$CURRENT" to make it work on the currently selected prop regardless of it's current name!
(of course the mesh has to be identical!)

• Now open your saved scene, copy the complete block between the lines "interpStyleLocked 0" and "blendType 0"
  and replace the according lines in your "injection" file.
• Make sure that the
  "indexes xxx"
  and
  "numbDeltas xxx"
  lines do match the original from your saved scene,
  and that all the lines
  "d xx xxxxxxxxxx xxxxxx" etc.
  from your saved scene are pasted in lieu of the placeholder line
  "//list of deltas here"!
  Because these are your actual morph data!
  .
• Save it as "My Injection.cm2" (--> cm2 - sic!)
  You can put this file anywhere in your library (the ".cm2" suffix is just to fool Poser from behaving silly!)
• Now open a new scene, load your prop, click the "My Injection" thumbnail in your library, and you'll have a brand new morph target in your prop.

• You use "actor $CURRENT" instead of "prop Whatsisname" because now you can apply it to any prop of the same geometry in a scene regardless of it's name.
• You save it as a Camera (.cm2) file to make it work independently of figures to be present in a scene.
  You could save it as a .pz2 file, but then it wouldn't work unless there is a figure in the scene.
  By making it a .cm2 file you can use it universally.
• There's no need to use PMD injections or Python scripts because the new Poser versions (>10) will create the new morph "on the fly" when you click this "injection" file"

	figure
	{
	}
	figure
	{
 

lines at the end are still necessary; in the past it was a trick to make Poser update the viewport, and I just kept them by routine. Probably you can omit them now.

Happy morphing!
