Osiris: Material group; how to get them?

[Khajiitos]

I am trying to make a proper nightmode, but despite colormodulating World and StaticProp there are still some unmodulated textures, and my question is - how can I get the name of the group? Example:

best bet would to be to decompile the .BSP and open it in hammer, if you open the object properties it will tell you its type (e.g. func_detail, prop_dynamic, prop_static)

Those boxes are rendered using fastpath, that's why they can't be color modulated.
It looks like the boxes are brushes so fastpath can be turned off by setting cl_brushfastpath cvar to 0.
