I’m sorry for late answer but my type of resource is movie clip witch is designed from several smaller MC (to be truthful is it a MC with four child MC which is character in each direction, each character are constructed from several movie clips in order to be able create animations in future for different poses/jobs, on last level there are Shape with Fill Color of part of Body.
Also i don’t use openFL plugin only i publish swf library and manually those entries that openfl plugin will add (If there is something more which add to haxe project oepnfl plugin than described in Flash Professional extension for OpenFL please tell me), also to be truthful is there any other way to create bitmapData from MC than BitmapData.draw() ?? I ask because in my project even though the mc display without any problems, in a case of bitmap sometimes there seems to show some problems like outline with missing pixels, or curve which magically becomes more straight, to be truthful currently i’m testing project only for windows, and as main platform i develop it, i will mainly focus on it, so i would be happy even if a better way to produce bitmap exist only for windows target.
