Verification builds and Platforms:

ver. 1.5.0.53, build 3739317, Win10
ver. 1.5.0.54, build 3790170, Win10

Summary:

Switching to a different geometry using a render controller does not immediately change the geometry ingame. The geometry changes after the entity is reloaded (reloading the chunks).

Impact:

Affects every piece of content switching geometries, includes Hex Chunk Challenge which is live.

Repro Steps:

1. Download the content "Hex Chunk Challenge" from the marketplace.
2. Enter Creative Mode.
3. Get the "Brown Bear" spawn egg and spawn a bear.
4. Tame the bear with cod (% chance).
5. Right click the bear with an iron helmet.

Observed Results:

The texture switches (ears turn grey) but the geometry does not till the player reloads the chunks, after which the helmet from the different geometry will appear.

Expected Results:

The geometry switches immediately like the texture and how it did in 1.14

Screenshots/Videos attached: Yes/No

No

Regression Builds:

This did not occur in 1.14.30, Build 3692779

Notes:

The render controller for the bear uses a texture and geometry array with "query.variant" to switch between the two. The variant is changed in the behavior file of the bear when interacting with it while holding an iron helmet.
