Somehow it is possible to render a scene with multilight enabled and not saving the mxi file. It was sad for me after waiting 6 hours rendering, I was not able to edit the light channels...
This has no sense, since it will not be possible to edit an unexistent mxi file. It would be great if, as soon as you switch the multilights ON, an MXI file should be saved automatically, somewhere with a default name and location!

Not sure what you mean....an mxi doesn't get automatically saved either when rendering with ml off. You can however specify before rendering that an mxi should be saved. Or, you can save one after you stopped the rendering, in which case the ml sliders will be saved with the mxi, if you had ml on.

Well, what happened to me is the following:

I had a rendering finished with multilights.
I forgot to set maxwell to save the MXI file.
As soon as the render was finished I started to play with the sliders for each light, and suddenly everything went black.
There was no way to make it work again.
Then I realized that I had not saved the MXI file, but it was late.
I had nothing.

As far as I understand you cannot edit mulilights if the MXI file was not saved. That is the reason I thought that it should be saved automatically in case of enabling ML.
