I came across
Hull decomposition of Obj used for hittest of models, there is a Blender plugin described in the readme.
I also found that there is some code for jmonkey that uses this within bullet physics for hittest?https://github.com/riccardobl/jme3-bullet-vhacd/blob/master/src/main/java/com/jme3/bullet/vhacd/VHACDCollisionShapeFactory.java
And there is also some Java bindings...
Thought that someone here might find them useful in theory you could add the plugin to blender create the model and then perhaps add to the bullet library used in Armory to make use for hit-test. Maybe a topic for future exploration.
