Release v0.83.0 — VRChat avatars & face mapping · Codemarchant/rexclaw

✨ Features

VRChat avatars look right. Avatars exported with SoulFlame VRM Exporter (Output: SoulFlame) now render with their real lilToon materials instead of the plain fallback, so skin, blush and see-through layers match how they look in Unity. Their eyelid motion, idle loops and animated hair and clothing physics come across too. Compressed VRM files (Draco, meshopt, KTX2 textures) now load as well.
Map your avatar's own face shapes. In the avatar editor's Tune face, every face part has a crosshair: pick the model's own shapes for it (search by name, with English hints for common Japanese names), weight them with sliders, or switch the part off.
Set up each feeling yourself. Tune face has a new Feelings section. For each feeling and level (light, clear, peak), you can turn the built-in parts off, add other parts, or add any of the model's shapes, such as heart or star eyes. Shapes like these switch on whole as the feeling arrives, so the eyes never go blank half-way.
New gestures. Companions can now stretch and kick. Goodbye, sleepy and squat have new animations.
Imagine image quality. A new setting next to the Imagine model chooses Auto, Low or Medium quality for grok-imagine-image-2.0 (the default, Auto, works as before).
Pinned model defaults. New installs now start on fixed model versions (grok-voice-2.0, grok-4.6, grok-imagine-image-2.0) rather than "latest", so an xAI update can't change a companion's voice overnight. Existing settings are untouched.

Calls with Sign in with Grok work again. xAI started refusing calls made through the subscription with "Payment Required", even with unused allowance. Calls now connect directly with the subscription.
Rexmaw Raids shows the ship again. The game's sea and glow effects were updated for the new 3D engine version, which had left the bay blank or flashing white.
Games update properly. After an app update, games no longer keep running old cached files.
Brows no longer change eye size. On avatars without named brow shapes, raising or knitting the brows borrowed a whole expression's eyes (shrinking pupils, half-closing lids and holding back blinks). Brow moves now use the brows alone.
Auto-tune on VRChat avatars. Blush and tear layers hidden inside the head no longer make Auto-tune shrink mouths and expressions to almost nothing.
Companions run a repeated tool call once. When a voice reply contained the same tool call twice, it no longer runs twice.

Credits and sources. SoulFlame VRM Exporter is listed under "Where to get VRM models", and the new animations and lilToon renderer are credited (English and Japanese README, Credits dialog).
