Hi Tom, Thanks a lot! Ben Le 14 déc. 2015 à 23:49, Tom Goddard <goddard@sonic.net<mailto:goddard@sonic.net>> a écrit : Hi Ben, You can set multiple solid rendering thresholds with the volume command, for example, vol #0 style solid level .5,0 level 1.5,1 For solid style the level is two numbers, the first being the density map value and the second is from 0 to 1 indicating the brightness (and also opacity). To specify more than one level you repeat the option.

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?
