I’m encountering a texture issue when tiling multiple kml/collada models using Cesium ion self-hosted.

Each individual model renders correctly when uploaded alone. Even when uploading two models together, there is no issue. However, when I upload many models at once and tile them into a single tileset, textures on specific models become corrupted. The textures appear fragmented or incorrectly mapped. Also, the same model consistently shows this issue, while others do not.

What is the cause of this issue, and how can it be resolved?
