Once you have the main Portal Mod running in your client, you need to activate this resource pack and place it in the right load order so its classic textures override the mod's default assets.
Activating the Pack in Settings
1. Launch Minecraft with the main Portal Mod loaded, then open Options and select Resource Packs.
2. Locate Portal Mod Portal 1 Blocks Resource Pack in the left-hand column of available packs. If it does not appear, click Open Pack Folder and make sure the pack archive or folder is directly inside your resourcepacks directory.
3. Hover over the pack icon and click the arrow to move it into the right-hand Selected column.
Setting Pack Priority
Resource packs load from bottom to top, meaning packs higher in the right-hand list overwrite anything beneath them.
- Use the up arrow on Portal Mod Portal 1 Blocks Resource Pack so it sits above the built-in Mod Resources entry and any general overhaul packs you use.
- Open your inventory or load into a world containing Portal Mod blocks. Check the inventory icons for chamber doors and fizzlers—if they show the older visual style from the first game, the pack is active and properly prioritized.
