how can convert Texture2D to BufferedImage?
BufferedImage img = ImageIO.read(assetManager.locateAsset(new AssetKey("Textures/GUI/Windows/Panel-BG.png")).openStream());

There are a couple different ways that I could answer this question but all but one of them is probably wasting my time. I just don’t know which one.
