Hi, I want to try to export a shading tree to an external shading language. To do so, I need to traverse the shading tree and translate all nodes into shading language commands.
I thought it could be useful to start with the leaf nodes and go up level by level until I read the shading engine. Does anyone know if there is an easy way to get only the leaf nodes of a shading tree? Of course I can do it the other way, starting from the shading engine and go down by analyzing the connected attributes. I'm still unsure what is the better way. -- http://groups.google.com/group/python_inside_maya
