that's not really what i wanted..
cause i want the rpg maker ressources to stay like the are, to make it easier to use ._.

don't get me wrong
it's easy to create a bitmap splitter inside the importer tools to split a 4x4 characterset into 4 1x4 framelines

But that disables the ability to select a specific frame pattern of a characterset like in rmxp. And think of autotiles. Autotiles are based on 48 tiles. If you just import 10 nom animated autotiles, you will get 480 bitmaps

and i'be no idea how to write a shader or how to merge shaders together (i tried to learn it from the manual for 8 months and gave up cause i couldn't write it into my brain)

Isn't there a solution to get that window effect without cutting the ressources?
