[MDL ED] Making A Monster

[The chaser]

1) By the moment, you cannot use Blender to make monsters with animations, you can create models (like a chair), however. If you want a monster with animations, you must use Maya 2008.

2) It's A LOT EASIER to simply tweak a monster of Amnesia, as you just have to change settings and textures. From scratch, you have to make the model, the texture, the animations, and tons of things more.

3) The reason you can't make monsters in Blender is because of the armature (or skeleton). The bones are exported a different way than maya, and the model editor doesn't recongize them. Therefore, any animation or skeleton you apply to your monster in Blender won't work or will simply crash model editor.
The animations must be made in a 3D modelling program, like Blender or Maya.

I hope this answered your questions
