Minecraft Version

What happened?

Mod Incompatibility Bug

Issue Summary:
When using the Flashback mod together with Curios API on NeoForge 1.21.1, the player model does not render properly in Flashback's playback or editing screen. The player appears either invisible or only the head is visible. Disabling Curios resolves the issue.

Reproduction Steps:

  1. Install Minecraft 1.21.1 with NeoForge.
  2. Use Sinytra Connector to run Flashback (which is a Fabric mod).
  3. Install Curios API for NeoForge.
  4. Record and play back a sequence using Flashback.
  5. Observe the player model during playback/editing.

Expected Behavior:
The full player model should render correctly during playback.

Actual Behavior:
The player model is either completely invisible or only the head is shown.

Tested Environment:

  • Minecraft version: 1.21.1
  • Flashback version: [e.g., latest Fabric build]
  • Curios API version: [e.g., 6.x.x for NeoForge]
  • NeoForge version: [e.g., 20.2.x]
  • Sinytra Connector version: [if known]
  • Java version: [e.g., Java 21]
  • OS: [e.g., Windows 10]

Additional Notes:

  • The issue only appears when Curios is enabled.
  • Possibly a rendering conflict.
  • I understand this is a hybrid environment (Fabric mod via Sinytra), but other mods function fine.
  • Let me know if logs or additional info would help.

Hello @TheIllusiveC4,

Just had the same issue and found this issue. Here's the log with a minimal reproduction environment: https://mclo.gs/gMjXtHG.

The environment was:

  • Java 21.0.7
  • Minecraft 1.21.1
  • NeoForge 21.1.194
  • Mods (all at the latest version when testing):
    • Sinytra Connector 2.0.0-beta.8
    • Forgified Fabric API (Sinytra's Fabric API Implementation) 0.115.6+2.1.1
    • Flashback 0.36.0
    • Curios 9.5.1

It actually seems to be a problem related to how Sinytra/Flashback handles server mods, if this information would help. Will open an issue later in the Sinytra Connector repo.

It may be better for you to post this issue to the Sinytra Connector issue tracker, as they're the ones more familiar with how they're implementing cross-loader compatibility and are more suited to evaluating if this is a mod-specific issue for Curios or something about Connector itself.

I'll see what I can figure out on my end though. Do you know of other mods like Curios that add rendering layers to players and work fine in this setup?
