Clay bucket, and variants with or water or lava have no texture. (Milk works)

• Minecraft: 1.16.1
• Ceramics: Newest version as of August 23 2020

There is no newest version. Type in the version number you are playing.

What other mods do you have installed? And do you have any resource packs installed? If nether, I need a copy of your game logs to verify the cause.

Closing for lack of response, it has no missing texture in my testing, so there is information you are not providing causing the missing texture.
