MPxNode Derived class doesnt have attributes categories.

[jonathan_ouellet]

Hello, I created a new class which is derived from MPxNode.  Everything works fine with the compute function and the input/output.  However, when I select my node and I go in the Attributes Editor tab, my attributes are not sorted by categories. 

My Node:

Locator Node:

Any clue why I don't have the Attributes drop down in my Node ("Node Behavior", Locator Attributes which should be MyNodeName Attributes) ?

Thanks !

Off the top of my head, I would guess that you need to provide an Attribute Editor template file for your node.

See Maya's "scripts/AETemplates" directory for examples.  This will be located somewhere like, "C:/Program Files/Autodesk/Maya2016/scripts/AETemplates".  When you make your custom template file, I recommend not putting it in this folder.  Instead, set the MAYA_SCRIPT_PATH environment variable (if you make a .mel template file), and put your custom template in a folder on that path.  Alternately, use the MAYA_CUSTOM_TEMPLATE_PATH if you make a .xml template file.  (Honestly, I'm not sure when you are supposed to use MEL and when you are supposed to use XML.)

Edit: Forgot to mention that the template must be named after your node.  So if your new node type is "myCustomNode", then your template must be called "AEmyCustomNodeTemplate".

Seems like this is what I need!

But I'm not very familiar with this.  Do you know how to specify that my node will use this file ?

Thx !

Oh its seems to be hardcoded with the filename !  AE{nodeName}Template.mel.

Thanks again.
