Supported Mesh Formats

The following file formats are supported by default in Simulant

• Wavefront OBJ
• glTF 2.0 - Khronos Group glTF ASCII and Binary Formats (Skeletal Animation Support)
• MS3D - Milkshape3D Animated (Skeletal Animation)
• MD2 - Quake 2 Animated Models
• BSP v38 - Quake 2 Level Format
• OPT - XWing OPT Model Format
• TMX - Tiled Map Format

BSP v38

The Quake 2 BSP file format is supported for mesh loading in Simulant. Much of the data in the BSP file is ignored, but the following is processed:

• Mesh data
• Textures + Materials (limited)
• Entities (limited, they are stashed in the mesh's data)
• Lightmaps (Currently not enabled due to a bug)

MS3D

.ms3d mesh files are fully supported. All versions of the format should be supported and loading an MS3D file should generate a mesh skeleton, and set the correct frame rate.

Animations need to be specified by keyframe before they can be played.

glTF

.glTF 2.0 files are supported, so long they are exported as Y+ UP. They are created as prefabs inside the engine. When animated, the prefab spawns an AnimationController, supporting joint-based as well as skinned animations.

Please note that IK constraints are not supported at this time, and must be baked into the keyframes on export to render properly.
