Quad drawing:
http://www.conitec.net/beta/draw_quad.htmThe bmap_rendertarget function can be used to draw the quad into a bitmap.
Particles over panels are possible since A8:
The effect_layer function creates the effect outside the level, just like layered entities. This way effects can be placed on panels or follow the mouse pointer. Particles created with effect_layer are rendered on the media_layer, and use the view settings from the camera view.
I´m no shader programmer - maybe there is a way to realize normal or bump mapping through post processing?
Then you could use bmap_process?
