Hi,

As I have read in the book of Jerem Birn (Digital Lightning and Rendering) it is advised to check the lights in isolation to discover anomalies caused by incorrect light positions and settings.

In Maya, when using the "Lightning/Use selected Lights" works this way, but only in the perspective and other orthografic windows... as I tried it does not change in the IPR and in the final render windows.

So when e.g none of the lights is turned on (none of them selected, Use selected Lights is choosen and total darkness is in the scene), but IPR and the final renderer too keeps rendering it with full light setup.. so how to do to render once only with "this lamp" then only with "that lamp" then "both together"..

It would be very tedious to set the light intensities to 0 each time I would like to switch a light off.

Thanks!
