View Full Version : SKY with no lights
scott frizzle 06-07-2006, 04:24 PM Can anyone tell me how to use the SKY plug in without having it generate any lighting in the scene? I have pre existing lighting and I just want to use SKY to generate a background, but I can't find any settings to adjust the SKY lights.
Thanks!

Interested in the answer. My current work around is to make the custom sun color Black. But I hope there is a better way.

just make sure it's emmitting gi and it'll act like a conventional IBL object.

True, assuming he wants GI from it. I think he just wants the image. You can bake the sky to a map. Someone pointed out that there is even a scene setup for that, find a recent thread about setting the correct colormapping numbers for that post.
So you bake the SKY to a spherical image and it sits on a sphere and you use a compositing tag set to 'composite background' and not 'seen by GI'. with shadow cast/recieve off, or just put the map in a luminence channel and turn off gen/recieve GI in the material.

Hi
I recently had to do this as well but appart from baking the Sky to a texture which will obviously make it static, there's another way as well which has the added benefit of not eliminating sky animation etc.:
1. Create your sky object.
2. Create a light (no matter what colour) with 0% illumination.
3. Open up the sky material's attributes and change the following settings:
General: Switch on the custom sun colour and change the colour to black.
Illumination: Switch off all the tick boxes.
Scene Objects: Drag the 0% light you had previously created into both the sun and moon link boxes
It's been a couple of months since I've had to do this and might have missed a setting or 2 so please let me know if it doesn't work so I can go re-check the Sky settings.

Hey thanks. That works indeed.
I was wondering myself how to do this.
Peace,

Thanks for the replies everyone. For this purpose simply making the custom sun color black did the trick, but those other solutions will surely come in handy when I need the Sky to animate.
The SKY plug in for me is like Sketch and Toon; I've been able to get good results from it, but so much time passes between projects where I need it that I forget half of what I know about it between uses. I spend a half hour or so just getting requainted every time. ;)
Thanks again!

hello,
using black for the sun color works for the illumination, but if you look at the sky where the sun should be, there is a big black hole. does not look too good in animations.
i have found a solution which is actually quite simple and uses part of the technique from Uncle-Ox.
-create a light (doesn´t matter what kind)
-in the sky options dialog under sceneobjects use the light as the sunobject
-then simply deactivate the light
- if you do not want GI you have to turn it off in the illumination tab
hope this helps
