In creation kit im building a level and trying to light it but when i try to use the shadow lights they only appear a red bulbs and dont show the light in the kit. they show up and work in the game but from videos iv seen them work in the kit so ... is there a setting to make them work?

you can only have four shadow lights visible at a time, using one shadow light at each room of your cell would be recomended.

You also might want to go to to the CK's File/Preferences ...click on the shaders tab and make sure shadows is checked-------if you have less than 4, this could be the problem.

You can hit the "lights on" button in the CK, which will simulate your lighting as seen in game. That, and the FX button if you have a fire or natural lighting, and also the Sky button for daytime light.

yup, it was the preferences. shadows were turned off. thanks it works now.
