The commentary about PointerProps and update callbacks appears to be
incorrect. Maybe it was broken in a beta release of Blender 2.79? Works
fine in Blender 2.79b.
This enables the Blender Mesh Normal panel and exports any double sided
mesh with double sided layers to Plasma. The implication is that the
mesh will be rendered twice in game--the second time with the winding
reversed. Wavesets marked double sided are ignored due to the runtime
generation of layers in game. Trying to make a double sided waveset is
therefore nonsense.
This allows directing the message to *all* modifiers -- this is
primarily only useful for ladders, but some other types may respect the
message. Also exposed the ability to send the message to child objects.

PotS is in worldspace when the mass is non-zero. Plasma likely detects
nonzero mass as "this object can move" and expects localspace. MOUL on
the other hand uses localspace if the object has a CI, otherwise
worldspace.
It appears that in Havok-physics enabled versions of Plasma, plEnableMsg
does not affect physics. Therefore, we have to send the PotS-era
plSimSuppressMsg to do this job.
MOUL/DX9 will not rt light any vertex with a near-zero component in its
normal. This prevents shadows and decals from appearing on flat surfaces
in Ages exported for the MOUL engine. Instead of fighting with the
pipeline and vertex buffer code in Plasma, we'll just clamp the values
here.
This allows for objects to print decals at runtime, like the baskets in
Eder Gira. Also, the same functionality can be hijacked for coincident
objects to exist as decals. This is basically a shortcut for adding hack
Z-flags to the base layer of a decal material.
This allows blend textures to be used for mesh transparency without
having to fiddle around too much. It was also a stab at fixing some
regressions in the MOUL engine around decals, but that bit failed,
sadly.
The soft volumes were previously in aproximately the correct location
but the exported normals were not unit vectors. This seems to have made
the resulting soft volumes not function as intended.
