[Tutorials] Part 5: Custom Attributes and Expressions

1. 선택한 오브젝트에 로케이터 그룹 만들기 

import maya.cmds as cmds selectionList = cmds.ls(orderedSelection=True, type = 'transform') if len(selectionList) >= 2: targetName = selectionList[0] selectionList.remove(targetName) locatorGroupName = cmds.group(empty=True, name = 'expansion_locator_grp#') for objectname in selectionList: coords = cmds.getAttr('%s.translate' % (objectname))[0] locatorName = cmds.spaceLocator(position=coords, name='%s_loc#' % (objectname))[0] cmds.xform(locatorName, centerPivots=True) cmds.parent(locatorName, locatorGroupName) cmds.xform(locatorGroupName,centerPivots = True) else : print 'Please select two or more objects.'

2. constraint 연결 하는 코드 

cmds.expression( alwaysEvaluate=True, name='%s_attractWeight' % ( objectName ), object=pointConstraintName, string='%sW0=%s-%s.%s' % ( targetName, maxExpansion, targetName, newAttributeName ) ) cmds.connectAttr( '%s.%s' % ( targetName, newAttributeName ), '%s.%sW1' % ( pointConstraintName, locatorName ) )

3. 그동안 구현한 스크립트 들로 움직이는 오브젝트 애니메이션 만들기

# expandFromFirst.py import maya.cmds as cmds selectionList = cmds.ls( orderedSelection=True, type='transform' ) if len( selectionList ) >= 2: targetName = selectionList[0] selectionList.remove( targetName ) locatorGroupName = cmds.group( empty=True, name='expansion_locator_grp#' ) maxExpansion = 100 newAttributeName = 'expansion' if not cmds.objExists( '%s.%s' % ( targetName, newAttributeName ) ): cmds.select( targetName ) cmds.addAttr( longName=newAttributeName, shortName='exp', attributeType='double', min=0, max=maxExpansion, defaultValue=maxExpansion, keyable=True ) for objectName in selectionList: coords = cmds.getAttr( '%s.translate' % ( objectName ) )[0] locatorName = cmds.spaceLocator( position=coords, name='%s_loc#' % ( objectName ) )[0] cmds.xform( locatorName, centerPivots=True ) cmds.parent( locatorName, locatorGroupName ) pointConstraintName = cmds.pointConstraint( [ targetName, locatorName ], objectName, name='%s_pointConstraint#' % ( objectName ) )[0] cmds.expression( alwaysEvaluate=True, name='%s_attractWeight' % ( objectName ), object=pointConstraintName, string='%sW0=%s-%s.%s' % ( targetName, maxExpansion, targetName, newAttributeName ) ) cmds.connectAttr( '%s.%s' % ( targetName, newAttributeName ), '%s.%sW1' % ( pointConstraintName, locatorName ) ) cmds.xform( locatorGroupName, centerPivots=True ) else: print 'Please select two or more objects.'

feedback .

lighting 과 rendering 복습이 필요하다 (anold, mentalray, vray etc )
