Change material bump strength in Python


I need to change material bump map strength in couple of dozens 3dm scenes and I thought it should be possible to have a Python script which would loop thru all materials in scene and if such material has a bump channel, change it % strength … I tried to goggle some info but found just how to create new mat.

Any idea how to access bump map strength param in Python?

Thanks for help!


This is the screenshot which illustrates what I am talking about. Tried to search a lot of resources but no luck. Any help highly appreciated, thanks!

@nathanletwory - is this something you can help with?

Check the video from this reply:

It will teach you how to investigate a Rhino material, and then apply the new information in your scripts.


great, thank you very much!
