Carbons

Carbon 1.21.1.9 (0.9)

• Align physical dropped-item shader shadows with the visible orientation, tumbling, grounding height and copy positions.
• Separate flat-item stack layers to prevent coplanar texture flickering.
• Keep block piles compact with limited offsets inspired by ItemPhysic Lite, replacing full-block vertical stacking.
• Apply matching stack offsets in compute, vertex fallback and shader shadow rendering; correct physics yaw angle units.
• Keep pickup-animation copies on the native rendering path so items travel toward the player instead of flashing at their original position.
• Remove smooth roll correction after landing: lay flat items down immediately and stop 3D items at their landing orientation.
• Preserve the configurable 0.8 cache update budget and existing lowered loader requirement: NeoForge [21.1.0,21.2).
• Client-side visual changes only; entity motion, collisions and pickup behavior remain unchanged.
