[ART] Model Editor Problem

[Your Computer]

Well this sounds logical but maybe you could explain me one more problem...I tried to import a mobile phone this time(Contists of Screen and the skeleton) so I created two mat files and the model editor seems to load it properly but when i press Start model test it dissapears...

I don't have an explanation for that, but the way it works in there is not exactly how it works in game. Take for example the enemy suitor. Testing out its animations shows a suitor whose animation is about at least two times slower than what it is in game. The HPL2 editors were never declared as completely stable by Frictional Games. Worry more about how it acts in game and not in the editors.
