# WeaveLoader.API Mod Assets Placeholder textures for the missing block and missing item (unresolved mod content). Stored in `mod_assets/` to avoid conflict with the `Assets/` C# source folder (Windows case-insensitivity). Copied to `assets/blocks/` and `assets/items/` in the build output. - **Blocks:** `mod_assets/blocks/missing_block.png` → icon `weaveloader.api:missing_block` - **Items:** `mod_assets/items/missing_item.png` → icon `weaveloader.api:missing_item` These are used when a world contains blocks or items from mods that are no longer installed.
