Some blocks or items may still look modern after you turn the pack on. Work through these checks in order.
Check the pack list
1. Open Options > Resource Packs.
2. Make sure Programmer Art DX is in the Selected column, not just in Available.
3. Make sure the built-in Programmer Art pack is also selected. DX only updates newer content and is meant to sit over the classic textures. Without Programmer Art, older blocks stay in the modern default style while new ones look retro.
4. Confirm Programmer Art DX is above Programmer Art. Use the arrows to move it up if needed.
Other resource packs
If you run more packs, the highest pack wins for any texture they both change.
- Move Programmer Art DX above other packs that change ores, Nether blocks, mobs or item icons.
- If you want another pack to control certain textures, place it above DX instead. Expect those textures to lose the retro style.
- To find a conflict, deselect your other packs, confirm DX works on its own, then add them back one at a time.
Reload and retest
- Press F3 + T in game to reload resources after changing the order.
- If you use shaders through a loader such as Iris or OptiFine, briefly turn shaders off. This shows whether the problem is the textures or the shader's lighting.
Once the order is right, ores, deepslate, Nether fungi, signs and effect icons should all show the classic style.
