In S2Engine SceneObject is the base class of all component of a Scene. SceneObjects have a set of shared parameters:

Parameters

pos	Object position in the world
scale	Object scaling transform
ang	Object orientation in euler angles (yaw, pitch, roll)
color	Object color. Works only if supported by the object, es. lights
model	Object model. Must click on apply to apply changes
cast_shadows	Cast shadows flag
name	Object name
dims	Dimensions of the object. Behaviour depends on the object. For rigid bodies It gives the dimensions of the collision shape
activable	This flag means if object must be active at game start
offset
script
maxDistance	Max visibility distance of the object
custom	Custom parameter. Can be used inside script
maxShadowDistance	Max distance the object can cast shadows
impostor	Object impostor material
colmesh	object collision mesh. Can be set if collision shape is set to mesh
terrainHeight	The y coordinate of the object relative to the terrain
modelLod1	The model resource used for first level of detail
modelLod2	The model resource used for second level of detail
modelLod3	The model resource used for third level of detail
earlyZCull
attachList
scriptParams
timeBasedLOD	This flag means if object LOD transition must be aplpied basing on distance or time
fsm	The Game Machine resource applied to this object
lodBias1
lodBias2
lodBias3
impostorBias
lodTransitionMul
transformID	this index means the order object transformation must be applied: minor values means object is transformed fisrt
