This improves the panel layout and fixes the issue in which
`plShadowMaster` exported with `maxSize` == 0, causing crappy shadows
in PotS and generally no shadows in MOUL.
This fixes two bugs with empty node socket spawning:
- The first time an empty is spawned, the link is moved to the last
socket.
- Unlinking a socket in the middle of the group would cause that socket
to be the one that's empty. This isn't bad per-se, but with Responders
being ID-based, it could result in some confusion.
Previously, Korman exported cameras without the "Maintain LOS" flag
applied, allowing cameras to swing through geometry. In the token of
better defaults and easier to understand objects, all the tracking
options have been audited for clarity and their exporting to the correct
camera type.
Previously, reusing node trees required careful thought and
specification of specific nodes in the advanced logic modifier. This
tedious requirement has been removed in favor of ensuring that the nodes
themselves take into account whether or not they should generate and
attach plasma objects.
This fixes an issue in which responders would get "stuck" at the end if
the last message had callbacks AND the responder was not attached to a
Python node.
Inspired by Unreal Blueprint's drag link+create list functionality. I
realize Blender has a few operators that do different parts of this job,
but they don't provide this well-polished functionality.
"Improve" is not quite the correct verbiage here because there were bugs
in the old code. The main issue is that any SceneObject with a
plPythonFileMod attached MUST have a CoordinateInterface attached,
otherwise the object would be invisible in game. Further, there were
some unreported oversights with regard to auto-generated modifiers that
have been fixed.
This isn't the best fix in the world. We don't really know what the user
did to cause the failure because of how abstract this code is. A proper
fix would be to ensure region modifiers can't get attached to non-mesh
objects. That won't fix already "broken" stuff in blend files without
being naughty/destructive, however.
Unfortunately, this does not prevent "DAG zero..." from appearing
period. Rather, it just overwrites any junk printed to the console
during the export. The ANSI version is rather limited compared to the
Windows version and completely untested...
Due to memory management issues, it is likely impossible to remove a
node in its own init() callback without crashing Blender. Now, we will
deactivate any output node operators if an output node is already
present in the tree.
Recall that PFMs are added as modules to the global modules dict.
Therefore, module names must be valid Python 2.x identifiers. This is
handled well for age names, but we've been neglecting to handle it for
PFM names. So, when Blender adds ".001" as a suffix to a duplicated
object, any attached PFMs will go down in a firey dust explosion.
Generally, with the unhelpful error message: "NULL result without
error in PyObject_Call".
