with athmospheric shaders or near-by light sources on, a lake is shown as tar pit... when both (athmospheric shaders and near-by light sources) are off, the same lake is shown nicely (transparent blue)... nvidia driver 169... (obsoleted) does show that lake correctly no matter what i select... linux kernel 2.6.25 needs nvidia driver 173.14.05... how can i c the lake correctly with nvidia driver 173.14.05? -arne
