Does anyone know how to make it dark inside a cave?

I have seen it done but don't have a clue how to do it.  Any ideas?

It's not easy.  SL's sun penetrates through all obstacles.  One way that helps a lot, though, is to make the prim walls of your cave emitters of black light.  You can do it two ways. 

1. Select a prim with your Edit/Build tool and then go to its Features tab and put a check in the box marked Light to activate it.  Set Intensity to 1.0, Radius to 20.0, and Falloff to 0.01.  Click the color picker window and select black.

2. Put this script in a prim....

default{    state_entry()    {        llSetLinkPrimitiveParamsFast(LINK_THIS,[PRIM_POINT_LIGHT,TRUE, <0.0,0.0,0.0>,1.0,20.0,0.01]);        llRemoveInventory(llGetScriptName());    }}

 That script should turn on the black emitter and then delete itself, so you don't have an extra script hanging around.

ETA:  Hmmmm.. That's odd.  I haven't tried this trick for a while, and I can't get it to work today.  That's disappointing.

Rolig's answer is VERY clever!  One point...don't make more than six of your prims light emitters.  The viewer cannot see any more than that.  Also, people wearing facelights may "turn off" the darkness emitters whenever they are closer to a viewer than the emitter, if the total number of local lights is exceeded.

Another way to do it is to make EVERYTHING dark on the parcel, using Parcel Windlight settings.  Not all viewers support this feature, though, so some visitors may not see your cave the way you intend.

A very simple way is to put a sign at the entrance:  For Optimum Viewing, Set your World Sun Position to Midnight.
