Thanks for the work on this mod! I’ve been looking into why the textures aren't loading, and it appears the files themselves (Honey_diffuse.png and barrelPallet_diffuse.png) are missing from the mod's file structure entirely. The XML references are pointing to them, but the files aren't in the archive. Would you mind checking the source folder and re-uploading the package when you have a moment?
The references i found in the i3d file hope this helps
