To speed up 3D model uploads in plugins, optimize file size and use plugin efficiency features.
Use compact formats like GLB or OBJ (avoid larger ones), delete unused textures/materials, and reduce polygons with decimate tools—smaller files cut upload time directly. Enable batch uploads or auto-optimization if your plugin supports them to streamline the process.
If uploads are still slow, test a small model first: if it works, the issue is file size; if not, check network/plugin limits and adjust.
