Name	Description
hierarchyLevel	When merging by hierarchy level this where the depth is stored
keepParent	Will merge each GameObjects with all of its own children.
mergeByRegionsStrategy	Number: specify the number of output GameObject (or the number of regions of output GameObject) Size: specify the diagonal size of the output regions
mergeStrategy	Choose whether to merge GameObjects into one GameObject or merge GameObjects by materials (one GameObject per material)
numberOfRegions	Specify the number of output GameObject (or the number of regions of output GameObject)
sizeOfRegions	Specify the diagonal size of the output regions (in Unity unit)
type	Merge All: Merge all objects from the initial model as a single object. To merge each selected object recursively with all of its child objects, select Keep Parent. Merge By Material: Merge all objects that are from the initial model and that share the same material. Merge Final Level: Merge the last hierarchy level below the input objects. Merge By Hierarchy level: Merge the specified hierarchy levels below the input objects. The selected GameObjects must be placed at the same hierarchy level. Merge By Name: Merge all input objects that share the same name. Merge By Regions: Merge input GameObjects within the same area

Name	Description
Icon	Icon to be displayed in Toolbox and Rule Engine. If null, no icon will be displayed. To support light and dark themes: specify light theme path. Dark theme file name should be the same with a "d_" prefix. To support selected and unselected states: selected files names should be the same as main files but with a "s_" prefix.
Id	The id of the Acton implementation. This id should be unique and is readonly. The id is the actual reference if the Action is serialized (in a set of RuleEngine Rules for example).
IsAsync	Should the Action be fired in as a Task
MenuPathRuleEngine	The menu path for the RuleEngine.
MenuPathToolbox	The menu path for the Toolbox.
Priority	The order to use when placing this Action in a list. If the value is -1, the display name will be used instead;
Tooltip	Returns the tooltip.

Name	Description
GetErrors()	Virtual method for Error checks before execution.
GetWarnings()	Virtual method for Warning checks before execution.
PostProcess(ref IList<GameObject>)	Use to modify the output after the 'Run' method is executed. Always executed on the main thread.
PreProcess(ref IList<GameObject>)	Use to validate/modify the input before the 'Run' method is executed. Always executed on the main thread.
Run(IList<GameObject>)	Abstract execution method. When creating a new Action, this method implementation will hold all the processing code. Executed on a background thread if IsAsync is true.
Run(OccurrenceList)	Runs in Pixyz context. To be overriden in the derived class.
Validate(object)	Called to validated/check the new input (new selection in the editor with toolbox action, or before running action in ruleset)
