Dear Paraview Developpers,

I wrote a Python Plugin to visualize solutions of our inhouse FE-software. Everything works fine and now I’m implementing some comfort features for my colleagues, such as which output should be visible after loading the data. Consecutively, I want to set the coloring of an output from “Solid Color” to “Material”.

The smproperties.xml looks at the moment like this, but I can’t figure out how to access the Coloring.  
Thanks for your time and help.  
Yours sincerely,  
Fabian Müller

Dear Mr. Westphal,

thanks for your answer. I wrote a workaround by using the smproperty in a first step for the rendering types and in a consecutive step I now use a python macro to color everything as I wish too.

Yours sincerely,
