I changed the model with gltfpack, but I found that the request for these files took a long time. These files were all on [https://preview.babylonjs.com](https://preview.babylonjs.com). My babylon.js is located in the place. Although it is large, but it takes a short time.

Is there any way to use the local babylon.ktx2decoder.js and MSC\_BASIS\_TRANSCODER.JS when loading the model?

How did you set up your local project? npm?

You can change the `KhronosTextureContainer2.URLConfig` [KhronosTextureContainer2 | Babylon.js Documentation](https://doc.babylonjs.com/typedoc/classes/BABYLON.KhronosTextureContainer2#URLConfig)  
i.e. `KhronosTextureContainer2.URLConfig.jsDecoderModule = "https://somewebsite.com/babylon.ktx2Decoder.js"`.

However I wasn’t able to get the files relatively from the local project, it has to be an absolute path. As described in this [Thread](https://forum.babylonjs.com/t/load-ktx2-de-transcoder-from-own-server/30324/4). I now set the paths by getting `document.location.origin` and adding to that.

Using relative urls should be possible. The code just doesn’t call `Tools.GetAbsoluteUrl` before storing the url. We do this for the Draco module, for example. Feel free to file a GitHub issue for this.
