Didnt' have time to reply to this earlier, but wanted some clarification:

"access" in what way?  I don't think the MTex and Texture objects give
full access to textures, but I've been able to write scripts that do
quite a bit.  Are you thinking of some other type of access?

This is also partly true:  I've used RenderData.setImageType() and
RenderData.setRenderPath() to modify the rendering file, but it doesn't
work great, especially for AVI files (actually, it doesn't work at
all).  I haven't use renderAnim before; all my scripts have worked
the other way (i.e.,a link on FrameChanged which runs my scripts).
