Here's what you need to do:
- Remove Light entirely from the materials selection. This selection thing should be ONLY for physics related alterations to a prim.
- Add Light Emitting as a check box. This should NOT make a prim "shadowless". Some people (one of my neighbors, for example) has made the walls of his entire house out of pure white Light prims, simply because the shadowless look is one he likes better than the shadowed one.
- Add a Self-Lit checkbox. This makes the prim "shadowless" much like my neighbors walls WITHOUT creating a light source.
- Tweak and include the Debug mode's Light Glows effect, and make a checkbox for it next to the Light Emitting option. Have you ever actually SEEN this effect? My GOD, it's amazing! Sure, it's SLIGHTLY buggy, showing up through the walls of my build, but WOW! I made a particle based fire, stuck a tiny light inside it, and turned on Light Glows and the REALISM of it was quadrupled! Wow! And some other places' look incredible with Light Bloom on too! My neighbor's house is not one of them. Of course, Light Glows will be a seperate option much like Local Lighting is.
Please?
Oh, and while you're at it could you get Obj <-> Obj communication too?
