Something completly breaks texture packs

This issue occures at both format 4 and 5

Player gets something like nausea fog, leaves visually dissappear after some distance as well as some colormap affected textures

I'm unable to attach texture pack as a file here, because it is very big and I'm unable to find exact files, but was searching for a while and discovered that something like nausea effect and leaves disappearing is caused by something in models/item file, but for the rest of issue I'm unable to find a clue.

Also when texture pack is loaded before opening a world there is no nausea fog, but just a transparent hole
