3D Art Asset File Types
The following file formats are used for static geometry:
File Type Where
Created
Description
*.cgf (Static Geometry File) DCC tool Contains static geometry data, such as grouped
triangles, tangent spaces, vertex colors, physics
data, and spherical harmonics data.
*.chr (Character Asset File) DCC tool The base character used for animations.
*.cdf (Character Definition
File)
Lumberyard Defines the base character and associated
attachments. This file is created with Geppetto
and contains a reference to the .chr file.

*skin (Character Skinned
Render Mesh)
DCC tool Contains skinned character data, including the
mesh, vertex weighting, vertex colors, and morph
targets.
*.fbx (Filmbox File) DCC Tool Contains mesh, material, camera, and animation
data. Provides interoperability between DCC
tools.
*.scenesettings (Scene
Settings File)
Lumberyard Contains configuration and rules settings from
an .fbx file.
*.abc (Alembic Cache File) DCC tool Contains non-procedural, application-
independent set of baked geometric data such as
baked meshes and their materials.
*.cax (CAD/CAE Exchange
File)
Lumberyard Contains compressed game assets read from
the .abc file and streamed in-game on demand
from disk.
*.trb (Terrain Block File) Lumberyard Contains terrain data and associated level objects
such as water and vegetation.
Material and Texture File Types
The following files are used for the Material Editor. For more information, see Working
with Shaders and Materials.
File Type Where Created Description
*.mtl (Material File) DCC Tool Contains settings for shaders, surface
types, and references to textures.
*.dds (DirectDraw
Surface)
DCC tool Contains compressed source texture files.
*.sbsar (Substance
Files)
Allegorithmic
Substance Designer
Contains procedural materials.
Animation File Types
The following file types are used for the Animation Editor. For more information,
see Animation Editor File Types.

3. www.claydesk.com
File Type Where
Created
Description
*.actor (Actor File) DCC tool A character with at least one bone.
*.motion (Motion File) DCC tool Individual animation clips for a character, such as
walk, run, and so on.
*.motionset (Motion Set
File)
Lumberyard Contains a list of motion files for a character. For
example, you can create a motion set
named Run.motionset that contains
the run.motion, sprint.motion, and jog.motion files.
*.animgraph (Animation
Graph File)
Lumberyard Contains the state machines, transitions, conditions,
blend trees, and so on.
*.assetinfo (Asset Info
File)
Lumberyard Contains the configuration and settings for
the .actor and .motion files. Animation Editor and
the FBX Settings tool can create this file.
The following file types are used for the Geppetto and Mannequin systems. For more
information on these file types, see Character Animation Files.
File Type Where
Created
Description
*.adb (Animation Database
File)
Lumberyard The Mannequin system uses this file to store
fragments and transitions. This is typically
referred to from the character Lua file and other
systems such the hit death reaction system.
*.i_caf (Intermediate
Character Animation File)
DCC tool Contains the animated bone data for one or more
characters in uncompressed format.
*.animsettings (Animation
Settings File)
Lumberyard Contains per-animation compression settings.
This is a sidecar file that is stored next to
the .i_caf file and describes how it should be
compiled by the asset pipeline.
*.caf (Character Animation
File)
Lumberyard The compressed version of the
intermediate .i_caf file. Contains on-demand
asset data that is streamed in and out of the game
as needed at runtime.

4. www.claydesk.com
*.chrparams (Character
Parameters File)
Lumberyard Contains skeletal characters. This file has the
same name as the .chr file to which it refers to.
*.dba (Animation Database) Lumberyard Contains multiple compressed .caf animation
files that are streamed in and out of the game
together. Created by the Resource Compiler and
defined in the .chrparams file.
*.animevents (Animation
Events Database)
Lumberyard Stores a list of assets with timed event markups.
Geppetto creates this file, which is mapped to
the .chrparams file.
*.bspace (Blend Space File) Lumberyard Define how multiple animation assets are
blended together. Blend spaces are
parameterized at runtime with movement
parameters such as movement speed, movement
direction, turning angle, or slope.
*.comb (Blend Space
Combination File)
Lumberyard Combines multiple blend spaces into one,
usually of a higher order, and represents a
multidimensional blend space.
*.grp (Group Files) DCC Tool Exported animation sequences used for track
view sequences.
Audio Asset File Types
The following file types are used for the audio system. For more information, see Adding
Audio and Sound Effects.
File Type Where Created Description
*.bnk (Soundbank File) Audiokinetic
Wwise
Contains compiled sound data and
metadata.
*.wem (Encoded Media
File)
Audiokinetic
Wwise
Compiled streamable audio file.
