Cthulhu head, original facial tentacles and ocular surfaces

Adaptation: the supplied sculpt's intact closed head and seated details were
isolated by connected anatomy. The original torso, arms, legs and wings are
not included in the runtime head asset. The head is uniformly normalized;
a compact geometry variant, red ocular shading, runtime materials, lighting,
and bounded facial/ocular animation were added. Original facial relief is
geometry, not a claimed replacement sculpt or baked normal map. Attribution
does not imply the creator endorses this project.

Supplementary tentacle A — source-derived sucker-bearing anatomy

Adaptation: hollow sucker geometry and a recovered source body section were
transferred to a long tapered, almost-straight neutral body. The supplied
coiled silhouette was deliberately discarded. Full and compact variants
use one continuous whole-body skin, 80 canonical units and 92 bones, with
an editable Blender rig and runtime whole-body motion. There is no separate
front/rear graft, runtime morph target or exported animation clip. Supplied
textures are not used or shipped; the site's existing green-violet tissue
treatment is applied. This is a source-detail adaptation, not an unchanged
source model. Attribution does not imply the creator endorses this project.

Supplementary tentacle B — source-derived ridged anatomy

Adaptation: recovered source section profiles and fold relief were transferred
to a long tapered, almost-straight neutral body. The supplied returning
S/coiled silhouette was deliberately discarded. Full and compact variants
use one continuous whole-body skin, 64 canonical units and 84 bones, with
an editable Blender rig and runtime whole-body motion. There is no separate
front/rear graft, runtime morph target or exported animation clip. Supplied
textures are not used or shipped; the site's existing green-violet tissue
treatment is applied. This is a source-detail adaptation, not an unchanged
source model. Attribution does not imply the creator endorses this project.

Derived displacement, roughness and neutralized albedo detail are packed into
local 4K/1K textures; runtime pigmentation is authored for this scene.

The intact biomechanical wings, chamber backplates, runtime hall geometry and
synthetic network choreography were authored separately for cthulhu.sh.
Supplementary rigs and geometry are source-detail adaptations as described
above. Editable authoring poses are not shipped animation clips. No
third-party audio, supplied tentacle texture maps or reference screenshots
are included in the website.
