I'd like to introduce Light Master V0.1a. The idea of Light Master is to focus on simplifying the workflow of lighting in Maya by having useful tools and settings all in one place. Currently the tool's main task is soloing lights. Soloing lights is essential when lighting but, unfortunately it can be a tedious and troublesome task. With this tool it is now a one click solution to specify one or more light(s) to hide or show.
At this point there's not too much to explain so here's the script. Just extract the MEL file into your script folder. Then type without the quotes `source LightMaster.mel` into maya's command line.
If you have any questions, issues, comments or ideas for future features please let me know.
