This is likely due to a resourcepack error, or you may have an outdated version of the resourcepack downloaded which is causing you to see missing textures; this happens when a new model is added to the pack, meaning you must update it to load them properly.

Here are a few solutions you can try:

• Try clearing your serverresourcepacks folder (found in your .minecraft).
• Try to properly load the resourcepack using the steps below
  • Make sure you're running 1.13.2 or above
  • Make sure resourcepacks are set to 'enabled' or 'prompt' via the multiplayer menu
  • Download and install the latest stable version Optifine for 1.13.2 or above https://optifine.net
• Attempt to reload your textures in-game using F3 + T

If you continue to find issues with this, feel free to contact me on Discord @KimiNoUso#9999
