Sunlight edges

tarquin · 31st May 2004, 12:23 PM

I'm having problem with sunlight.
I've got it to shine on my terrain just fine

but it's also shining inside a tunnel that leads into the side of the terrain that's made with BSP. And where there is a Zone Portal, I go from completely lit to absolute dark.

How do I stop it shining into the tunnel, and how do I get a smooth fade?

Place a plane (bsp probably best) over the area you want to shade, place a fully transparent texture on it, and turn off all collision. that way you won't see it ingame and you won't be able to interact with it. rebuild lighting, under it will be shadowed, unreal shadows aren't raytraced, so it won't calculated transparency, place it in the right position to shade the tunnel correctly. Should get you closer

If the surface is BSP that you want to fade, you can alter the light map size on a per face basis, so make it a smaller number that it is (in the surface properties). This will have the odd effect of blurring the shaded edge.
