Before Continuing:

• Check you are using the latest version of the mods and its dependencies
• Always include a latest.log if you are crashing
• Remove known hacky mods such as: Optifine, Fabric API/Connector on forge, and every kind of hybrid server like Mohist and Velocity. None of these are supported. Also try without other lesser usual suspects like Sodium and Lithium.
• If you are unsure which mod is the culprit.
  Disable all of your mods and enable them 1-2 mods each time to isolate the culprit
• Confirm that there is no existing issue with a similar description submitted in the list of issues.

Describe Issue

This bug concerns an interaction with the mods TerraFirmaCraft (TerraFirmaCraft-Forge-1.20.1-3.2.18) and Patchouli (Patchouli-1.20.1-84.1-FORGE), although those are not the source of the issue.

The newest version of Supplementaries is failing to produce item model textures for woods made of TerraFirmaCraft wood types. This has only started happening as of 3.1.37, while in 3.1.36 the item model textures worked fine. Since the changelog speaks of "improved texture gen code", I presume this bug stems from that change
