UgcRays::Scene answers the two ray queries the UGC server makes: the nearest
hit for the hidden faces' paths (never the triangle a path leaves) and any hit
for the ambient occlusion rays. Two backends:
- builtin: the two hierarchies the queries had before, moved unchanged (each
built the first time it is asked), so the files made are the same bytes
- embree: Embree 4 on the job's thread (a device per worker thread, no threads
of its own, so its time counts in the CPU budget), watertight, the skipped
triangle filtered out
UgcHsr::Options::rays and UgcRender::AoOptions::rays pick the backend; both
default to builtin, and nothing sets them yet.
Check: the UGC tests (builtin's files keep their hashes; UgcRays tests compare
embree's hits, hidden faces and occlusion with builtin's).

The fleck texture was 50 soft round blobs of one size, bright in the
middle and fading out, which read as a smudgy dot pattern. LEGO's glitter
bricks have many small flat flakes (about half a millimetre) of which
most look faint and a few catch the light. The flecks are now flat
flakes of glitter_fleck_size (0.05 model units, i.e. 0.5 mm; 0.7 to 1.3
of it) with a one-pixel edge, each as bright as its facet catches the
light (0.3 to 1 of glitter_fleck_opacity, 80%, weighted towards dim),
80 a tile by default. The texture grows (128 to 512) to keep a fleck 3
pixels wide. New settings glitter_fleck_size and glitter_fleck_opacity;
glitter_density defaults to 80. Only glitter output changes.
Check in game: reprocess a glitter model; close up, the flecks are small
crisp flakes of varied brightness, not blurry dots; from a few metres
the brick still reads as its color with a fine glitter.

Every glitter brick had the same flecks in the same places: the UVs were
the vertex positions projected on an axis plane, so bricks a whole tile
apart (and every brick of the same shape at the same spot in its own
model) looked identical. Each brick now has a number of its own
(UgcGlitter::BrickSeed, from the model's id and the brick's index, kept
per vertex in Mesh::brickSeeds) that turns the projection by an angle
and moves it by an offset under a tile, differently for each axis
plane. A model made again gets the same patterns; every LOD of a brick
the same one. The icon now draws the flecks on the UVs the .nif has
(Mesh::uvs read back by FromNif). New setting glitter_random (1; 0 puts
the same pattern on every brick as before). Non-glitter models are
byte-identical (hash tests unchanged).
Check in game: reprocess a model with several glitter bricks of the
same shape; the fleck patterns differ from brick to brick.

- The client puts a shape in its sorted, blended pass only when its
NiMaterialProperty alpha is under 0.99999 (ShaderCommon::GetAlphaFlags
0x0109f5a0; the NiAlphaProperty blend flag isn't read); at 1.0 it's drawn
solid with blending off. Transparent (and transparent glitter) shapes now
get a material with alpha 0.9999, as the S01_Alpha shapes of the game's own
brick models (res/BrickModels/ndmade) do; opaque shapes keep 1.0. Models
with a transparent brick change; the others are byte for byte the same.
- dUgcServer's files move into Bricks/, Model/, Render/, Formats/ and
Processing/ (the CMakeLists says what each holds); includes are unchanged.
