I wanted to create an set driven key relationship in such a way that if one object visibility is set to ON all remaining objects in the set should turn off .
For example there are 5 switches in my scene where I need the other four switches to turn OFF when I activate one switch.
How can I code such thing in Python?
Thank you.
Here's a more procedural way to go about it with set driven keys, so you could have as many sets with as many objects as you want.
This will create a single attribute that will drive the visibility of all members in different sets. As you change the driver's value it will only display one set.
import maya.cmds as cmds driver = "pSphere1" # Define the object that will hold the switch attribute. set_names = ["set1", "set2", "set3", "set4"] # Define set names to effect. cmds.addAttr(driver, ln="switch", at="long", keyable=True, min=0, max=len(set_names) - 1) # Create switch attribute on driver. for i, set_name in enumerate(set_names): set_members = cmds.sets(set_name, q=True) or [] # Collect all of the set's members. for member in set_members: for j in range(len(set_names)): cmds.setDrivenKeyframe(member, at="visibility", cd="{}.switch".format(driver), dv=j, v=i == j) # Set an sdk on each member that will set its visibility 
Use this code as a starting point:
import maya.cmds as cmds def on1(): cmds.setAttr('pSphere1.visibility', 1) def on2(): cmds.setAttr('pSphere2.visibility', 1) def on3(): cmds.setAttr('pSphere3.visibility', 1) def on4(): cmds.setAttr('pSphere4.visibility', 1) def on5(): cmds.setAttr('pSphere5.visibility', 1) def off1(): cmds.setAttr('pSphere1.visibility', 0) def off2(): cmds.setAttr('pSphere2.visibility', 0) def off3(): cmds.setAttr('pSphere3.visibility', 0) def off4(): cmds.setAttr('pSphere4.visibility', 0) def off5(): cmds.setAttr('pSphere5.visibility', 0) cmds.window(width=100) cmds.columnLayout(adjustableColumn=True) cmds.radioCollection() rb01 = cmds.radioButton(label='1', onc='on1()', ofc='off1(), off2(), off3(), off4(), off5()', sl=True) rb02 = cmds.radioButton(label='2', onc='on2()', ofc='off1(), off2(), off3(), off4(), off5()') rb03 = cmds.radioButton(label='3', onc='on3()', ofc='off1(), off2(), off3(), off4(), off5()') rb04 = cmds.radioButton(label='4', onc='on4()', ofc='off1(), off2(), off3(), off4(), off5()') rb05 = cmds.radioButton(label='5', onc='on5()', ofc='off1(), off2(), off3(), off4(), off5()') cmds.showWindow() Hope this helps.
