Looking at the LW 10 Sigraph 2010 video, it looked like Lightwave made spritesheets with Spritegen and then had no direct way to read back in the spritesheets. It looked like the demo guy used a planar map and moved the section of the image via the graph editor. Does that mean Lightwave can not read in the sprite sheet the same way it writes it out? Like if the user inputs in the width and heights of the frames of animation on the sprite sheet along with the number of images, it should be able to pluck out the images off the sheet.
