Is it possible to script a lamp object so the texture will switch to emmissive (full bright) when the lamp is switched on and switch back to non-emmisive when the lamp is switched off?
I have seen around scripts for controlling lights but nothing for changing a texture in an objects materials besides a slideshow set that uses extra materials as slots for calling preloaded textures.
You will see that effect in the light bulbs on the benches in the Reflex4 workshop experience:

The way I did it was to have two models of the bulb: one with and one without the emissive filament. But I also used a Reflex4 light script and an attached point light to do gradual dimming effect.
@Galen, I tried to visit your workshop last night but I could not walk beyond the wooden sign saying "...loading".
You say you use two different complete models of the lamp or just that your lamp has 2 versions of the filament in the same object and somehow you make one or another visible?
To be sure, I'm not talking about the lamps overhead. I'm talking about the naked light bulbs on some desks that are controlled by your interactivity.
I use Reflex4 sliding door scripts to swap one whole light bulb model for another. But you could do it by swapping the filament inside the bulb. I just would not recommend that because it's harder to line that up perfectly. My light bulbs don't have to be perfectly aligned with anything on the desks.
Looks good. I tried to find where the hidden lamp comes from but didnt find them ^^
I guess another way could be modeling a lamp with pieces for both on and off states and embedding 2 animation frames. In one frame the one of the pieces is hidden somewhere inside the lamp, if there is space or positioned below the lamp, on the other state they swap places. Then a click trigger will call one or other animation for on off look.
Yes, that's definitely an option. If you added a light source to the lit bulb, you'd need to make sure to put it out, as it were, when the light was off.
in my case, i use animated object.. so with a script you can control the animation that hides emissive or not emissive part
Can the emmisive value of a material in a surface be animated without having to have a duplicate of the surface, both playing peek-a-boo between on and off states, one with zero emmisiveness and the other with some emmisive?
I tried in Blender keyframing different values for diffuse intensity or shading emit but once in Sansar scene that has no effect.
No.
Hmm, this system seems more limited than plain old LSL.
You're used to being able to change many of the visual properties of prims in script, like size, texture shown, and tint. SL's script API certainly offers more flexibility in this area than Sansar's script API. Sansar offers pretty much none of this for right now. I think they will eventually get us this sort of capability, but there has not been an announcement (that I know of) of when.
