[Closed] rendermap does not render alpha chanel

hi all,

I’m rendering sprites for a game. The sprites need to be output in 2 sizes ( for different screen resolutions )

First I render the large sprites. Then I pass these large sprites to rendermap to generate the smaller sprites. The problem is that the smaller maps have no alpha!

I’m reaching the end of my rope… I’ve tried so many methods, nothing works…

does anyone have any advice? thanks!
