yeah texture splatting was what i was searching for. i already found some code snippet and was half through putting this beast into my code: http://phpfi.com/352238 when i found out that if i create a png with half-transparency in itn then pyglet will handle all this stuff on its own :D :D :D well as for the palette switching: i can compensate this by pre- processing the images and just loading more files into memory if it is too hard or gpu hungry to do this. do i gain any advantage by storing my tiles and map object as 256 color images or are they converted to rgb data in video memory anyway?
