Okay, as of now, in the SVN there is support for simple scrolling textures. Scaling, opacity, and other options will hopefully be coming in the future.
A few things to note:
All animation loop repeatedly
. Try to make sure that the texture in your last frame looks the same as in your first frame so that the transition will be seamless.
Animating stencils, decals, or alpha blending layers has not been tested. It's possible that flags will get overwritten when animating and that the desired effect will be diminished. If you do try it though, let us know what happens
Animation is done of a per-layer
When you open an IPO Curve editor window in Blender and select Material from the list at the bottom, there is a little box beside the dropdown list with a number inside. That number is the current layer. The first texture is layer 0, the second texture is layer 1, etc.
The layers are in the same order as the textures that are specified for the material.
Currently, any layer that has any form of translational IPO curve is exported as a layer animation. At this time, only the Ofs (translational) curves will actually end up in the .prp file at export.
Please report any bugs, and have fun
