Verification builds and Platforms:

ver. 1.21.202.0, Win10 

Summary:

When updating resource and behaviour packs to 1.21.2, all existing custom 3D geo blocks are displaying rotated 180 degrees within the GUI (players inventory and creative menu).

Instead of using the default north value, blocks are being rendered in the GUI as south facing.

Impact:

This would prevent a pack getting passed by CR, as blocks are displayed backwards in the inventory, making it hard to decern what the item is. Especially if custom blocks are re-creations of vanilla blocks such as stairs, which will need to be rendered in the exact same rotation as vanilla blocks.

Repro Steps:

1. Create a custom 3D geo block in 1.21.2
2. Ensure the facing of the block model in block bench is north.
3. Notice the block is rendered backwards (south facing) in the inventory

Observed Results:

Blocks rendered facing away from the player (south)

Expected Results:

Custom blocks be rendered in the correct facing in the inventory, which would align with the placement direction of the block.

Yes,

Regression Builds:

This did not occur in 1.20.8

Notes:

This seems to perhaps be caused by the introduction of "item_display_transforms", in 1.21.2, however due to it being locked behind upcoming creator features, its not possible to use this to revert the rotation bug,
