I've tried using the "inheritAttributesFrom() method of MPxNode, but none of the strings I pass in to the function work. I'm not even sure what the correct string should be -- is it the name of an MObject subclass? Or "texture2d"? (which I tried, and didn't work)
Is there another way to create a node that acts just like a File Texture node with my extensions without having to reprogram all the functionality involved such as the filtering, color balance, UV coverage, wrap, etc.?
Any help is greatly appreciated. Thank you!
