I remember seeing a lighting tutorial video of a spherical model with the refreactive logo on it... can someone point me in the right direction? I think it was by radiance.

Yes, I've done that...

Basically:

nothing.

perhaps I have a faulty copy? although I suspect I am still missing something.

perhaps someone could point me in the direction of a good tutorial on the subject instead?

ta.

Thanks...

I've played with temperature/power etc, and still no color. Would it be possible to post a quick idiots guide to making a red cube glow red? in the form of:

select material > diffuse >RGB = red > emission > blackbody > power 30% > temperature 60%?

Thanks

ps. I am using blender if that is at all relevant.

Having spent too long trying to work this one out myself, so can someone please help me create some coloured spot lights? I have tried making the light casing colored so it reflects the colour of the clear bulbs, but but everything is bright white light no matter what I do with the sliders.
I am ...
