With the new Texture Transform class developed in these video's you are able to animate textures that are laid overtop of geometry. The Texture Transform class lets you move, rotate and scale textures.
VMK25A/B has been split into two parts so that the download file size is a little bit easier to work with. Because of this, VMK25A will only play up to the beginning of 20min. VMK25B contains the rest of the video. After you download both parts, you can extract all VMK files (from 25A and 25B) into one directory to allow you to watch the entire VMK in one go.
