Change material bump strength in Python

[standa (Stan)]

Hi,

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!

Check the video from this reply:

Add layer with new material with Rhinocommon

I recorded a short video on how to find what you can change in Rhino materials. In short: save out the material to file, open it to inspect. Take note of the parameters you are interested in and then use https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Render_RenderContent_SetParameter.htm on your material instance, properly bracketed by https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Render_RenderContent_BeginChange.htm and https://developer.rhino3d.com/api/RhinoCommon/htm…

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