Simply cannot export compatible models from Blender 2.74

[sycon senti]

I make my models in Blender and export them into Amnesia: The Dark Descent just fine.
There are some things that absolutely have to be right in order to work properly.

The model itself
- For the smoothest results, make sure you have the model opened and nothing else in the scene. While it's possible to export only selection, I would advice you to delete everything else apart from your model. Things like "camera", "light" or even "box" if it's there from the startup file.

- The optimal way is to have ONE mesh for the model and ONE UV texture applied to the model. (make sure to create a material in materials tab and add a image texture in the texture tab) --- Having more meshes with different textures is possible, although can be achieved by exporting the two models separately.

- If your model has armatures, it is crucial you make it work in blender before exporting.

- You don't need to have triangular geometry ON THE MODEL ITSELF, just make sure you export it to COLLADA (.dae) and check "Triangulate" in the export options. That is the only requirement, if you previously checked some other options you need to set it to default first by restarting Blender.

AFTER EXPORT
- You have to put it in the Amnesia directory, either Static_objects or Entities

- Then you need to open it in the MODEL VIEWER before using it. Viewing will generate other required files.

- If it's a static_object it will be accessible in Level Editor as long as it's been viewed and is in the static_objects folder or any subfolder.

- Entities need to be edited with Model Editor and need body.

I've tried everything you said, but I'm still having the same problem. I have managed to export a cube to amnesia but anything more still crashes the program.
