Models
A model file can contain a 3D model, such a character, a building or a piece of furniture. The model is imported as multiple Assets. In the Project view, the main imported object is a model Prefab.
We can import a model by two ways:
Right click on Project view → Import New Asset
Asset menu of the top navbar → Import New Asset
Exported 3D files
This files are smaller and have a modular design.
At make a change to the file, the time to re-import or export the model is slower than the proprietary files.
The supported formats are:
.FBX
.dae (Collada)
.3DS
.dxf
.obj
Proprietary formats
Any change in the file will be reflected quickly in Unity, which make faster iterations in development.
Are bloated with unnecessary data.
Through conversion, can support this formats:
Max
Maya
Blender
Cinema4D
Modo
Lightwave
Cheeta3D
Sketchup
Contents of an FBX
A FBX file can content
Meshes
Animation
Blend Shapes, deformations of the mesh to achieve several shapes, like facial expressions
Textures/Materials
Smoothing Groups, soft or hard the edges of the model
