EntitiesBeGone is a shader pack. You turn it on the same way as any other shader, and it makes every mob, player, dropped item, armor stand, painting and item frame invisible. Vanilla lighting and the normal Minecraft look stay the same.
Enabling the pack
1. Make sure a shader loader such as Iris or OptiFine is running. Shader packs will not appear without one.
2. Put the pack file in your shaderpacks folder. You can open this folder from the shader menu in step 4.
3. In game, open Options → Video Settings.
4. Open the Shader Packs menu.
5. Select EntitiesBeGone Shaders from the list.
6. Click Apply or Done and return to your world.
Creatures, players and items should now be gone from view. The terrain and your builds look exactly as they do in vanilla.
Checking that it worked
- Look at a pasture or village. Animals and villagers should not be visible.
- Drop an item from your hotbar. It should not show on the ground.
- Look at any paintings or item frames. They should disappear as well.
If entities are still visible, go back to the Shader Packs menu. Confirm that EntitiesBeGone is the selected pack and that shaders are not switched off in your loader.
