*Verification builds:*

1.13.0.10

*Summary:*

Resource packs that override the player's look do not show the modified player models/textures/animations. (Using the example pack from Slack as a reference)

*Impact:*

We are unable to override the player, something we were able to do for a few builds now.

*Repro Steps:*

1. Create and join the provided world. The world has the example pack from #partner-announcements in Slack. Look at the player model.

*Observed Results:*

The player looks like the vanilla character (Alex/Steve/Whatever skin you have on), with its respective animations.

*Expected Results:*

The player should look like a penguin, with its respective animations.

*Screenshots/Videos attached: Yes/No*

No

*Regression Builds:*

1.13.0.9 (MCM-805 makes it difficult to test in this version. The latest version that this pack can be properly used in is 1.13.0.4)
