Matching the Sky

Is there any technique, using shininess, scripts, special textures, whatever will work, that will change a prim's visible appearance to match the Linden sky (whatever the sky looks like at that time of day)?

I'm trying to make the bottom of my skyboxes less obtrusive. I'm using alpha cloud textures for now, but the objects and avs on the platform still show through the transparent parts of the clouds, and the clouds themselves still look rather cartoony from a distance. I'd like the bottom of the platform prims to be opaque but look transparent, as if you're seeing the Linden sky through them.

Unfortunately, prims are rendered by a different method than the sky is, and thus look different in different lighting conditions. I settled on a no-alpha texture that was a screen shot of the noon sky, with clouds, as seen from about 100 M up.

I also tried placing an alpha-rextured platform below the skybox itself. But no matter what I did, it still was quite noticable as 'something different in the sky'.

Perhaps invisiprims? I don't think that will work, howecer, as I think all the testures behind the invisiprim must be alpha textures, and this the avatars and many other thinsg in the skybox would remain visible, even if you could use invisiprims to cloak the skybox itself.

I had the pleasure of doing a scripting project that displayed a texture based on the time of day (the angle of the sun, to be more precise). An avatar maker wanted her cat prim eyes to dialate according to the level of light and I used the height of the sun to control which picture was displayed on the prim.

You might get better results if you had several opaque sky textures to match different light conditions for different times of day and used a script to cycle through them according to the position of the sun.

I'm not sure how well your idea would work anyways. If you were able to somehow have the prim change to the color of the default SL sky, theres no keeping people who switch to "sunset" mode from seeing something different.

Heres an idea. Theres a neat cloud generator that makes clouds that change color with the default SL sky depending on the time of day. I got one in the Bora Bora Isles....very pretty.
