How to Combine Suren's Pack With Other Resource Packs Without Conflicts
Why Conflicts Happen
Resource packs work by overriding textures. If two enabled packs both contain a texture for the same Sophisticated Storage chest, only the higher one in the list is used. This is the most common reason a player installs Suren's pack and sees no change, or sees only some chests update.
Ordering Packs Correctly
Open Options, then Resource Packs. The right-hand column is your active stack, read from top to bottom. Place Suren's Sophisticated Storage Resource Pack above any pack that also modifies Sophisticated Storage textures, and below packs that change things you want to keep, such as UI or font packs. There is no single correct order for every setup, so adjust and check the result in-game after each change.
Testing and Troubleshooting
After reordering, click Done and look at a Sophisticated Storage chest. If it still looks default, try disabling other packs one at a time to find the one overriding it. Remember that packs only affect what the game renders on your client; other players see their own packs. If you play on a server, your changes are personal and do not alter the server's files or other players' visuals.
