Custom levels for Jak 2/3 now support envmapped TIE geometry. The TIE
extract was also changed to ignore materials that have the specular flag
set, but are missing a roughness texture.
Jak 2/3 now also support the `build-actor` tool.
The `build-custom-level` and `build-actor` macros now have a few new
options:
- Both now have a `force-run` option (`#f` by default) that, when set to
`#t`, will always run level/art group generation even if the output
files are up to date.
- `build-custom-level` has a `gen-fr3` option (`#t` by default) that,
when set to `#f`, will skip generating the FR3 file for the custom level
and only generate the GOAL level file to skip the potentially slow
process of finding and adding art groups and textures. Useful for when
you want to temporarily edit only the GOAL side of the level (such as
entity placement, etc.).
- `build-actor` has a `texture-bucket` option (default 0) which will
determine what DMA sink group the model will be placed in, which is
useful to determine the draw order of the model. Previously, this was
omitted, resulting in shadows not drawing over custom actors because the
actors were put in a bucket that is drawn after shadows (this behavior
can be restored with `:texture-bucket #f`).
Two new flags were added to the Blender plugin to allow reusing the mod
and/or eye draws of the original model that is being replaced. Works
pretty well for eyes, but the blerc draws can cause some Z-fighting with
the non-moving parts of the model.
Also a small refactor to the merc replacement code to de-duplicate some
code by moving stuff to `gltf_util.cpp`.
When a material in Blender has its IOR level changed to anything other
than the default value of 0.5, the `KHR_materials_specular` extension is
applied during the glTF export, which is what we use to check for
envmaps in custom models. If an envmap is undesired, but the IOR value
was accidentally changed, the program would assert during model
processing if there is no metallic roughness texture attached to the
material.
Since this is an easy mistake to make and is hard to spot, this adds a
better error message for such cases.
- Bug fix to KD tree splitting, should fix cases with bad vertex
colors/alphas.
- Normalize normals instead of asserting if they are the wrong length.
**the fact that blender exports normals incorrectly is a bug and I doubt
their implementation is correct if you've scaled things on only on
axis.**
- Automatically resize metallic texture (envmap strength) if it doesn't
match the size of the rgb texture instead of asserting

This only applies to the background for now:
- support for alpha for vertex colors in custom levels
- switch time of day palette generation from octree to k-d tree
- support for alpha masking in custom levels
- support for transparent textures
- support for envmap in custom levels

This adds a feature to `build_actor` to support importing skeletons and
animations from .glb files.
Multiple animations are handled and will use the name in the GLB. The
default `viewer` process will end up playing back the first animation.
There are a few limitations:
- You can only have around 100 bones. It is technically possibly to have
slightly more, but certain animations may fail to compress when there
are more than ~100 bones.
- Currently, all animations have 60 keyframes per second. This is a
higher quality than what is normally used. If animation size becomes
problematic, we could make this customizable somehow.
- There is no support for the `align` bone.

This does a couple of things:
- The `custom_levels` folder was renamed to `custom_assets` and contains
`levels`, `models` and `texture_replacements` folders for Jak 1, 2 and 3
in order to keep everything regarding custom stuff in one place.
- With this, texture replacements now use separate folders for all games
- A build actor tool was added that generates art groups for custom
actors
- Custom levels can now specify what custom models from the `models`
folder they want to import, this will add them to the level's FR3.
- A `test-zone-obs.gc` file was added, containing a `test-actor` process
that uses a custom model as an example.
The build actor tool is still very WIP, the joints and the default
animation are hardcoded, but it allows for importing any GLB file as a
merc model.
