I often find myself needing to do the same alterations to all the materials coming out of other applications. As a simple and current example, I need to import FBX files from the tiltbrush VR painting app, which can often consist of dozens of materials all of which have to be rewired in the same way - set to double sided, multiply vertex color node with the existing texture sample input, swap the output of the texture sample from RGB to alpha. A great candidate for automation. Now, I thought I could do this with python but so far I’ve only figured how to change the material properties to set the material to two sided, but no idea of how to add nodes and change connections to the graph. Is it at all possible?Is there a different way of achieving that?
