Troubleshooting Missing Crystal or Flowing Ore Textures
If your crystals still look completely default or underground ores do not show the flowing style after enabling Crystal Vanilla Tweaks, a load-order conflict or paused animation setting is usually the cause.
Checking Pack Priority and Reloading
1. Open Options > Resource Packs and check the Selected column on the right. Move Crystal Vanilla Tweaks to the very top of the list so another pack cannot overwrite its block textures.
2. If the pack does not appear in the Available list at all, click Open Pack Folder and check inside your resourcepacks directory. If unzipping created an extra outer folder around the actual pack files, move the inner folder directly into resourcepacks.
3. Return to your world and press F3 + T on your keyboard to force Minecraft to reload all active resource pack assets without restarting the game.
Restoring Flowing Visuals with Video Mods
If refined crystals appear properly in-game but the flowing ores look static:
1. Check your Resource Packs menu to verify whether the flowing ores came as a separate pack option that still needs to be moved to the Selected column.
2. If you run OptiFine or a similar video optimization mod, go to Options > Video Settings > Animations and turn Terrain Animated on.
