I'm trying to tweak the procedural sample project (GenerateHeightMap) found on this site to accept an animated height map and can't figure it out. I get a single frame rendered fine and have added code to update the Texture2D frame attribute, but the GetPixel call still doesn't want to read anything but the first frame's imagery. I've debugged it to the level of seeing that the Texture's frame attribute is being updated (I can read and print the value) but no visible animation. Very strange. If I add a small changing term I get that animation, indicating that all the functions are getting called correctly. It's almost as if the texture frame change isn't getting into the pipeline correctly. Any one have any thoughts on this? I'm totally stuck. Thanks!
