MEL - Material attribute Command

jayantbhatt007

Hi, I'm working on a script where I want to create a Button for "show material attribute" when we right click on the object. For eg.
I have selected one sphere and when I click on that button it will automatically open its material property.
I don't know Material attribute Command.

Thanks in Advance

try this: 

1. open maya 
2. open the script editor
3. under the history menu check on "echo all commands"

this will mean that everything you do will now show up in the script editor. You can then either copy or paste these commands into your script or look them up on the documentation.

Thanks for your reply hi for cube 1 here is the command (  showSG pCube1; ) but about other objects in the scene If i want to see their property I  know it is showSG ;
but looks like I have to add something after   showSG;   so It can show it material properties.

You need to get the material node that's attached to the object. 

first you should use listRelatives to get the shape node

then you should use listConnections to get the shading group and then again to get the material connected to the shading group

at least that's how I'd do it. If you can already get the shading group you can just use listConnections to get the material.

Another thing you can use to find out how commands work is the "whatIs" mel command. This will tell you if a proceedure is a script or a embedded command.

in the case of 'showSG' it tells me that it's a script written by the maya developers - so you can look at the code for it yourself.
