Retroview works with Minecraft's own vanilla graphics engine instead of relying on heavy extra mods. You switch it on from the normal Resource Packs screen, not from a separate shader menu.
Enabling the pack
1. From the title screen or the pause menu, open Options, then Resource Packs.
2. Click Open Pack Folder. This opens your resourcepacks folder.
3. Make sure the Retroview file is in that folder. Then close the folder and return to the game.
4. Find Retroview in the Available list on the left. Click the arrow to move it to the Selected list on the right.
5. Click Done and let the game reload its resources.
Checking that it took effect
Load into a world and look for these changes:
- Lighting should look like an old retro game rather than the usual smooth vanilla shading.
- Colors should shift toward the tones of a vintage screen.
- Blocks and items should have a dated look from the pack's classic visual effects.
Compare a familiar spot with the pack on and off. A grassy area at noon and a torch-lit cave both work well. If nothing looks different, go back to the Resource Packs screen and confirm Retroview is in the Selected column. Some setups also run a separate shader loader. If yours does and another shader pack is active there, turn that one off so you see Retroview's look on its own.
