Now that cloudbison can render (Radeon GPU via Xvfb, or llvmpipe software), added scripts/tools/screenshot_rig.gd + scenes/dev/ so a scene can be booted, run a few frames, and its rendered frame saved to PNG -- caught three things the headless smoke never could: - limbs floated detached from the torso: widened the torso and overlapped the arm/leg boxes into it, and pulled limb depth in behind the torso front so they stop z-fighting. - proportions were scrawny: reworked to Roblox R6 ratios (2-stud torso, 2-stud arms/legs, 1-stud head) with the head clearly pegged on top. - the walk swing was a 40-deg lunge: STRIDE 0.7->0.42 rad, separate 0.32 arm swing, KNEE 1.0->0.5. Reads as a walk now, not a crouch. test_level lighting was near-black on the shaded side (ambient was disabled) -- colour ambient at 0.8 + a stronger key light, so the avatar reads in-world. avatar_preview.tscn (AGP_PREVIEW_WALK=1) renders the assembled avatar walking in place for quick visual checks. Verified: avatar smoke 14/14 source + exported pack; fresh-clone boot PASS; eyeballed in rendered screenshots (game scene + walk sequence).

## Procedural locomotion for the placeholder blocky avatar.

##
|
|
## There are no animation clips yet -- this just swings the upper arm/leg bones
|
|
## around their local X by a sine wave whose phase advances with distance
|
|
## travelled, bends the knees on the rear half of the stride, and eases the
|
|
## whole thing back to the rest pose when the character stops.
|
|
##
|
|
## The owner sets `speed` (horizontal m/s) every frame; setup() is given the
|
|
## avatar's Skeleton3D. Bones are addressed by canonical name, so this works
|
|
## for the local player and for snapshot-driven remote players alike.
