[Closed] Extending Photometiic lights

Hello All,

I am creating a plugin and want to extend Photometric Lights.
1 . I noticed that the Extended light doesn’t work in Mental Ray, it only works in Scanline Renderer.

What i am exactly trying to do, is create a helper object which contains few options to quickly change light settings, Like Position, Type of Light (Photometric, Spot, Omni) etc.

2. I am facing a problem with lxAt for Photometric, changing the lxAt through Maxscript doesnt change the intensity. and i dont exactly know how the lxAt and intensity calculations are done.

Can anyone help me with either point 1 or 2.

Thanks
