/** /**
* This method loads the textre from outside the blend file. * This method loads the textre from outside the blend file using the
* * AssetManager that the blend file was loaded with. It returns a texture
* @param name * with a full assetKey that references the original texture so it later
* the path to the image * doesn't need to ba packed when the model data is serialized. It searches
* @param blenderContext * the AssetManager for the full path if the model file is a relative path
* the blender context * and will attempt to truncate the path if it is an absolute file path
* @return the loaded image or null if the image cannot be found * until the path can be found in the AssetManager. If the texture can not
*/ * be found, it will issue a load attempt for the initial path anyway so the
protected Texture loadImageFromFile(String name, BlenderContext blenderContext) { * failed load can be reported by the AssetManagers callback methods for
if (!name.contains(".")) { * failed assets.
return null; // no extension means not a valid image *
} * @param name the path to the image
