The dumb string lookup probably worked most of the time, but with recent
changes that can cause layers and materials to be renamed to things not
matching the pattern exactly, it's better to explicitly lookup the keys.
This will prevent Dynamic Text Maps from seemingly "breaking" for no
reason just because the lighting strategy changes.
I'm probably late to the party, but I have found that PotS can't handle more than 8 RT lamps on one material. This might vary by target engine, though, so no failure pronouncement is made.
In a previous changeset, the Advanced Logic modifier was changed to
defer exporting logic until the very end of the export process. This
means that many nodes are designed with the assumption that all
non-logic PRP objects are fully exported by the time they are exported.
LogicWiz modifiers, however, violated this assumption by exporting
during the main export() phase.
So, this adds a new `pre_export()` phase for all modifiers that lets
them generate logic trees and even entirely new Plasma Objects safely.
Futher, old LogicWiz modifiers have been tweaked to not leak junked
objects if the export fails in the middle of those modifiers.
This will allow us to automate releases with the Blender 2.79
"experimenntal nightly" codebase. This is great because the newer
Blender uses Python 3.7 (instead of 3.5). This pulls from my fork of
Blender, which has a number of build improvements added on top.
In user testing, the "Bake All" operator overwriting the "Col" layer was
blowing away too much manual shading, reducing the usefulness of the
feature severely. This changes us to using the "autocolor" layer and
making it a somewhat ephemeral coloring layer. Any "autocolor" layer
generated by the exporter should be removed when the export finishes.
Otherwise, it should persist.
You can now bake "finalized" lighting to either vertex colors or a
lightmap image. This can be done either from the toolbox or from the
individual lightmap modifier. The purpose of doing this is to allow the
artist to opt-into a workflow where they can chose when to incur the
performance penalty, instead of on export. The downside is that the
artist now has to manually click a bake button. But, for some Ages,
especially "finished" ones receiving small updates, there is no need to
rebake the lighting each export.
