Setting Up a "Sky Dome"

[davedavidson]

ok here goes
think dome /sphere
think 75 lights with look at controller all pointing into the center
arrange the lights in different planes
i think that is it not sure though


u could use more lights too but why bother


try it and see:bounce:

Use DICloner, from DITools. Given a sphere with say 40-odd vertices, it will clone a light at each vertex. As _dd said, make the light a spot light with a target tag. You'll have to crank the brightness right down though otherwise it'll end up atomic-bright. Then use a sunlight for the key light.

The advantage is you can fiddle with the settings of just one loight to affect them all.

OR...

Use a big sphere around the scene with polygon normals pointing inwards (reverse them), give it a texture with just the luminance channel on and use Radiosity. But be prepared for 9873645876435-hour rendering times...

u could as i do use instanced lights too as this will mean u only need to control one light
as for the material version of sky dome i dont like it that much cause u aint in control of the shadows etc
and i hate that, well not hate but u know wat i mean
