When exporting a PLY 3D model, textures often go missing because the PLY format doesn’t embed texture files—they’re stored separately, so broken file paths or incomplete UV mapping are the main causes. PLY prioritizes geometry, so it depends on external texture images and UV coordinates to apply textures; if the export process skips texture files or fails to save UV data correctly, the link between the model and its textures breaks. To fix this, save all texture files in the same folder as the PLY file and double-check that your 3D software exports UV data properly—this maintains the texture connection.
