i need someone who can tell me how to change a map's daytime into nighttime using sapien\geurilla

You need to create new lightmaps.

First you will need to use a different sky tag with darker ambient color values and lower radiosity power values.

You then go into the scenario tag in Guerilla and swap out the old sky tag for the new one.

Then open sapien and press the "~" key. Type in "radiosity_quality 0" then press enter. Then type "radiosity_start" and press enter. You should see three numbers at the top of the screen begin counting down from 1 to 0. When all three reach 0, type "radiosity_save" you should now have a darker level.

You may want to back up your level because this will overwrite the original lightmaps.
Also, if you want higher quality lightmaps, type "radisoity_quality 1" however, this will take much longer to complete.

ur telling me if i just replace the sky in geurrila and run radiosity, the textures on the ground will appear darker?

Yes

i put the sky in there and its creating the radiosity now. ill let u know how it goes. thanks
