Hello

I would like to add several threshold markers for volume solid rendering. I would like to do it in a script. I guess the only way is to do it through a python script.
I tried modifying the solid_levels and solid_colors attributes of the active volume but I could not find how I can then get the depending volume attributes, such as transfer_function and the gui (both rendered volume and the volume viewer dialog) to be correctly updated. Could anyone please give me a few pointers?

Thanks in advance
