How add custom object in amnesia custom history?

[Traggey]

Export your model from 3D's using the DAE format, place the model where it needs to go, usually static_objects or Entities folders. Set up a proper texture preperably in DDS format and use the tools provided with the level editor to create materials and setting up the entity.

Also make sure your Max model uses the texture located withing the amnesia directory, otherwise the game won't be able to load your model.
