Log and leaf textures are showing as the missing texture. Using 1.17.0 fabric. The game log prints something like this for every log and leaf: Using missing texture, unable to load minecraft:textures/blocks/leaves_spruce.png : java.io.FileNotFoundException: minecraft:textures/blocks/leaves_spruce.png and the selected packs are the "backport" and "alpha" packs.

Figured it out: Was using the backport instead of the base pack.
