How to Combine Pixlli With Other Resource Packs Without Conflicts
Understanding Pack Order
Minecraft stacks resource packs from top to bottom. The topmost pack wins for any file it contains, and lower packs fill in the rest. Pixlli changes GUI, font, and many block textures, so it will overlap with almost anything else you run.
Choosing What Wins
Decide which pack should own each category. If you want Pixlli's GUI and font but another pack's blocks, put the other pack above Pixlli so its block textures override, while Pixlli still supplies GUI and font files the other pack lacks. If you want Pixlli's blocks but a different font, put the font pack above Pixlli.
Practical Steps
1. Open Options → Resource Packs.
2. Drag packs in the Selected column to reorder them.
3. Apply and check the inventory, chat font, and a few blocks in-world.
4. Adjust order and reapply until each category looks right.
Avoiding Breakage
Don't run two packs that both heavily rewrite GUI at the same time unless you accept one overriding the other. If a texture looks wrong or missing, move the responsible pack up or down one slot and reapply. Keep Pixlli enabled as a base layer when you only want its font and GUI.
