 ### To Do
-- crashing sometimes - no idea why,
-- bones are not triangulated,
-- nulls are not triangulated,
-- crash when loading trooper,
-- display cloth testing
+- optional display bones, shadow, collision,...
 - integrate into a software:
--> gui open file ( + drag and drop),
 -> list all msh under a directory,
 -> display shadows,
 -> display colisions,
 -> lights,
 -> handle render flags,
-- draw more then one model,
-- use different textures for one or multiple models,
-- take a look at destruction
