meshlight emit color rgb or info from textures

[MattMR2]

Hello,

Is it possible to use meshlight to emit simple color rgb (if I remember well, it's possible to emit RGB from meslight) and the big question is it possible to use meshlight who emit light from texture (use textures as subrate the RGB) ? well, I work under maya with the maya indigo exporter and some stuff are still in developpement (but the stuff already done is great ) Could you answer me, so, with xml's bloc... because textures are not curently implemented in maya to indigo exporter and the material editor and object editor are still in developement. The last question I read in the indigo's features that's possible to modulate phong specular reflection with textures

Can use diffuse texture for substrate and specular texture to modulate specular reflection.

Could you explain me to how to do ? in xml format.

I EVER SAW THE ONLINE DOCUMENTATION BUT NOT FOUND ALL ANSWERS, LIKE MESHLIGHT WITH TEXTURE... NO ANSWER...

Thanks

Matt
