Fixing Lootr Containers That Still Look Vanilla

Check the Load Order First

Almost every case of "the pack isn't working" comes down to load order. The support pack must be placed above the main Excalibur pack in the Resource Packs screen. Drag it upward until it sits at or near the top of your enabled list, then confirm. Packs higher in the list win conflicts, so the Lootr textures need to be above the base pack to take effect.

Rule Out Other Conflicts

If the order is correct and containers still look vanilla, another resource pack may be overriding the same Lootr textures. Temporarily disable every pack except Excalibur and this support pack, then reload. If the textures appear, re-enable your other packs one at a time to find the culprit and move the support pack above it.

Also confirm you are actually looking at a Lootr container. Lootr replaces naturally generated loot chests with its own version, but chests you place yourself in creative or from your own inventory are ordinary chests and will use vanilla or Excalibur textures instead. Only Lootr-generated containers get the special appearance.
