Given that the Plasma World (read: age) is defined per scene, it seems
appropriate to limit the export to the current scene. Other scenes could
potentially have other age definitions...
This introduces the ability to version nodes. Responders have been
bumped to version 2. The difference is that v2 responder nodes maintain
a list (hopefully) all responder states on the responder itself. Each
state has its own socket and displays its index for usage in python
scripts. For better predictability, any states that are only linked to
another state's gotostate socket will be exported at the end of the
state list.
Arbitrary data from a material's layer flags were able to creep into a
DSpan's criteria, causing geometry that should go into the same span to
spawn a new DSpan with an identical name. Only one of the DSpan objects
would be exported, and Uru would either show crazy stuff or crash as a
result.
On the surface, this allows lightmaps to be exported as PNGs. However,
it also includes a light refactor of image exporting to facilitate
requesting export formats and the targeting of plImageLibMod. This
should better enable #96.
Due to our disabling of texture baking when lightmapping, Blender would
not be able to cast light through transparent materials. Now, we revert
back to something resembling the manual method of lightmapping from the
bad old days of PyPRP.
Do note that because we attempt to batch object baking as much as
possible, I have disabled baking lightmaps to transparent objects.
This is because the transparent objects would need its textures disabled
for it to be baked to, but with the textures disabled, the renderer
would be unable to correctly determine the object's transparency. D'oh!
It would be possible, I suppose, to move them into their own batch, but
that makes the state machine a bit more complex. It would be better to
wait for someone to need that functionality, I think.
This fix only changes the behavior to use whatever the original
filename is. A complete fix would involve managing sound files and
ensuring that they are ogg-compressed.
Adds a framework for dealing with deprecated logic nodes. First
implementation is for Responder Commands, which hooks the messages
directly onto the Responder States. Note that the old socket definitions
are left alone because the upgrader will need that data.
This commit removes the ability for Responder State nodes to specify
Responder Command nodes. Now, Responder State nodes reference Message
nodes directly. Messages that support sending callbacks can now
reference other messages as linked outputs.
Note that old node trees are currently broken and will need to be
reworked by hand. TODO is to automatically upgrade those old command
based node trees. Also, LOGICWIZ code using command nodes needs to be
updated.
As it turns out, enumerating a collection that can be modified is a bad
idea. Indeed, Blender expects that we won't do this. Sometimes, it
appears to work, however, other times, Blender is unable to handle it
and the internal data gets corrupted, causing a crash.
