[Opensim-users] Windlight and LightShare in Opensim 0.7

[M.E. Verhagen]

I think your windlight is working :)

The lsGetWindlightScene expects a list as a parameter to be given. You gave
an emply list in your example. In that case the function returns a empty
list.

I do not understand the logic in implementing that function in the way it
was done, the function matches the integers given in the list with the
windlight parameters already in the opensim memory. (I would rather like it
when that function would give the list with the settings back, must be
something with the lsl lists ? Can't we use cs to list and manipulate the
windlight settings ?)


Try this script:
