Question about lighting and func_brush

is there any way to make the func_brush that I choose stay in fullbright? I made a few brushes that are parented to a jeep, and they don’t seem to light ever (that is until I use my flashlight on it. Is there anyway I can set the func_brush to fullbright, or some other, full of light equivalent? I couldn’t find any kind of info_light option.

Find the vmt of the texture you are using, make a copy of it and change the words “LightmappedGeneric” to “UnlitGeneric” at the top of the vmt.
