Default drawdistance is 1000, and the dome is 1000.
so you can do either :
- If you have a camera object, increase range in the editor panels
or
- Decrease the Sun's child object to 950 (skysphere) using the scale parameters in the editor
or
- Increase camara drawdistance using camera:SetRange(0.01,2000)
or
Hack FPSPlayer.lua adding the line above just below camera:Create()
or
Use the postoprocess hack : http://www.leadwerks.com/werkspace/topic/10337-having-issues-with-zooming-out-in-the-terrain-editor/#entry76292
