Scene one and scene five hold the DTE generated terrains. The four remaining scenes show how these can be employed with specially mapped materials for foam or curvature to take advantage of the high resolutions used. Important Note. These are demanding scenes and are processor intensive. Do not expect instant results.
I recommend watching these related videos to get more from this product. Note that, the videos do not exactly mimic the content of the product, but rather cover the keys concepts involved. This is an advanced topic and, so far as I know, one that has not been extensively explored.
