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.
The lightmap modifier is now a more general "Bake Lighting" modifier
that can control how vertex colors are baked as well. The default vertex
color baking behavior is unaffected. It is now identical to adding a
Bake Lighting modifier, changing it to bake vertex colors without
specifying a pass.
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.
Added the Render > Lighting modifier that lets one specify whether or not
we should forcibly use RT lights. This allows us to change the light
baking rules to allow the baking of nonanimated Plasma lights when this
setting is disabled. The modifier also has text explaining what the
lighting results should look like.
The ViewFaceMod is presented as a Swivel component, with artist-ready
presets for the typical Sprite and Billboard, as well as an advanced
'Custom' option which exposes additional features.
Still lots of considerations:
- Need to make faux lightgroups to avoid baking Plasma RT lights
- Still need to bake vertex colors
- Still need to export Plasma RT lights (D'oh!)
But, this is definitely a step in the right direction!
