Content Creation

Formats supported by CGI Studio 
 3D File Format: FBX 
 While import software (Autodesk FBX SDK) supports several file formats, due to limitations of different formats, Scene Composer supports FBX import only. 
 Supported 3D Content 
 
 Mesh: Geometry as Array Buffer, indexed Array Buffer  
 Nurb: converted to Mesh  
 Patch: converted to Mesh  
 Material: Ambient color, Diffuse, Emissive, Specular, Specular Power  
 Light: Spot, Directional, Point  
 Camera: field of View, near Plane, far Plane, aspect Ratio  
 Animation: Translation, Rotation, Scaling, Visibility 
 Scene Graph: Object position, deep Groups, flat Groups (i.e. linked objects) 
 Skeleton: converted to Group 
 
 2D Image and Texture Formats 
 A wide range of 2D content is supported for texture generation: 
 
 Jpeg - .jpg, .jpe, .jpeg  
 Portable Network Graphics - .png  
 Graphics Interchange Format - .gif 
 Truevision Targa - .tga  
 Windows Bitmap - .bmp  
 Tagged Image File Format - .tif  
 Various others 
 
 During image export, gamma correction must be disabled! 
 
 Content Creation Rules  
 Procedural Shaders 
 Procedural shaders and special hardware shaded materials are not supported by Candera and not exported by FBX plug-in. Use only textures and standard material properties like diffuse color, specular, emissive and ambient. 
 Procedural Meshes 
 Procedural generated meshes are not supported by Candera and not exported by FBX plug-in. Convert your procedural generated meshes to static meshes before exporting. 
 Reflective Materials 
 Reflective materials are ignored by Candera and not exported by FBX plug-in. Reflective effects have to be done by environment mapping in Candera. 
 Material Count 
 Only the first material of a mesh will be considered by Candera. All other materials are ignored. 
 Animations 
 A keyframe sequence cannot contain keyframes with different interpolation types. If a keyframe sequence has different interpolation types Candera takes only the interpolation type of the first keyframe into account. (linear, spline or step) 
 
 Different Handling of 3D Coordinate Systems 
 Almost every 3D DCC tool uses an own interpretation of the 3D coordinate system. Due to this mix-up of coordinate systems, it is not always possible to mix the content of this DCC tools without any problems. Here some examples: 
 Autodesk 3ds Max 
 Autodesk 3ds Max uses +Z as up-vector and a right-handed coordinate system. 
 Autodesk Maya 
 Autodesk Maya uses +Y as up-vector and a right-handed coordinate system. 
 MAXON Cinema 4D 
 MAXON Cinema 4D uses +Y as up-vector and a left-handed coordinate system. 
 CGI Studio  
 The Scene Composer and the Candera rendering engine are using the default OpenGL coordinate system which is Y as up-vector and a right-handed coordinate system.
