Lighting problems with models

[Spike]

I've done a model of a volumetric waterfall, the texture of the water is white. But when I compile it on the map it looks orange (due to the light_enviroment)
and has some shadows under it. My question is, how can I make it look white? Can I tell a light to only texture the model and not the brushes?

use info_lighting. Stick it in a box somewhere away from the rest of the map with lighting inside it that you want your waterfall to have, then put the name of the info_lighting in the correct field in the model's properties.
