Example 4 with AssetKey

use of com.jme3.asset.AssetKey in project jmonkeyengine by jMonkeyEngine.

/**
     * This method loads the textre from outside the blend file using the
     * AssetManager that the blend file was loaded with. It returns a texture
     * with a full assetKey that references the original texture so it later
     * doesn't need to ba packed when the model data is serialized. It searches
     * the AssetManager for the full path if the model file is a relative path
     * and will attempt to truncate the path if it is an absolute file path
     * 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
     * failed load can be reported by the AssetManagers callback methods for
     * failed assets.
