Plasma game installs are a per-user config item and should not be stored
in a blend file. Considering that we will be adding more per-user
configs, namely Python 2.[2|3|7] install directories, it seems like a
good move to go ahead and move the games over.
A common error when developing with Korman and Korlib is to forget to
recompile _korlib on changes in the upstream C++ code. This will prevent
the errors from being catastrophic and will revert the user to the
python reference implementation with a minimum of fuss.
If the texture cache doesn't return images in exactly the order or way
that libHSPlasma is expecting, it raises a RuntimeError. We can detect
that we used a cached image and regenerate the data in that case...
instead of just outright failing with "image data size mismatch".
This operator takes a file as an argument and builds a cubemap from it.
Valid options are to supply the output from Plasma's
Graphics.Renderer.GrabCubeMap console command. The operator will find
the other five files and generate a cubemap with the faces saved by
Plasma. Otherwise, any arbitrary image can be supplied. If the filenames
do not fit the expected format, any missing faces will be replaced by
the face specified in the file selector. This will generally result in a
cubemap with six identical faces.
Previously, we allowed OpenGL to generate all of the mip levels for us
in a mipmap. This was pretty doggone fast and worked reasonably well.
However, with cube maps, we will need to use images that are not always
backed in Blender... this is because Blender stores cube maps as one
single image instead of one image per face. So, we need to be able to
generate those mip levels, preferably without touching Blender's
`Image.pixels`, which is slower than Christmas...
Also of note... `Image.gl_load()` will actually scale the iamge to a POT
when Blender is using OpenGL ES... but not on other platforms. So, now,
we just ask Blender to load the image and deal with the POT-izing later.
The con here is that the pure python implementation of the image scaling
function is SLOOOOOOOW. We're talking ~40 seconds to process a 1024x1024
mipmap. No one should be using the reference implementation, however,
and the C++ implementation shows no noticable slowdown over the OpenGL
code.
Whew.
Cube maps in Plasma are six separate images; however, Blender expects to
be supplied with one image that encompasses all of the cube faces.
Therefore, our texture cache needs to be able to support many images for
one request.
This provides the artist the ability to disable exporting layers that
would be DynamicCamMap (fast) in MOUL but DynamicEnvMap (slow) in PotS
in one fell swoop. Please note that disabling env map exporting will NOT
prevent waveset environment maps from exporting.
Blender used to not specify COMPAT_ENGINES on the physics panels. It
does now, and the new poll methods are incompatible with ours. This
results in lots of noisy errors being raised when in Blender Render mode
with the Korman addon active.
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.
Unfortunately, packed images don't appear to store any kind of modify
time attribute. In the case of those, we're just idly hoping that we can
find one on disk.
Previously, the C korlib used a custom buffer class to avoid a memcpy
operation. However, pyMipmap expects binary string (PyBytes) objects, so
this changes the code to use them. Future work would be to continue
using PyBytes and removing the copy. For now, there are bigger fish to
fry...
Some operators, namely the bake operator, require there to be an
active_object. The lightmap operator manages the selection, so this only
fixes Blender whining about the context being incorrect due to a
technicality.
