Setup:
I'm running Maxwell 3.1.0.2 with 3ds Max plugin 3.1.5 on Windows 7 64-bit Enterprise. I'm using 3ds Max Design 2015 (17.0 SP3) to setup my scenes.

Issue:
I have a number of scene files that share lighting and camera rigs. I imported the camera and lights from an existing template of mine, so their object and material names are all identical from one scene to the next. I calibrated my light settings using multilight and saved the values to an ".emixer" file.

The problem is that the order of the lights listed in Multilight differs from one scene to the next, probably because I manually imported those objects into each of my final scenes as opposed to making a template scene with the camera and lights 1st and then adding my photographic subjects into copies of that scene 2nd. I didn't think having the multilight channels in random orders would be a big deal as long as the channel names were the same, but now when I apply the ".emixer" file in an "MXI Batch Processing..." request, it tries to apply the ".emixer" settings to the multilight channels in the order they are listed in the "emixer" file, instead of by the name of the multilight channel. In other words, it takes the 1st multilight channel and gives it the emixer settings for the 1st light. Then it takes the 2nd multilight channel and gives it the emixer settings for the 2nd light, and so on. The problem happens when multilight channel 1 is called (for example) "Light A" and the 1st light listed in the ".emixer" file is called "Light B". Maxwell applies the settings for "Light B" to "Light "A". I always thought it did the lookup by name, but it's definitely not doing that this time.

I zipped up 2 conflicting MXI files with an ".emixer" file that works on one but not the other. Fair warning, the download is almost 1.2GB. It's also in a secure directory, so please PM me to get the credentials.

Are you using 3dsmax plugin? I've noticed that the order of the lights changes every time I open the file.
If I launch the render in the same session the order does not change, but if I close max, reopen, load the same scene and launch the render the order has changed.

Yeah, I'm using the plugin 3ds Max. It's version 3.1.5, which as of this post, should be the newest one. Even so, I would have expected Maxwell to read the multilight settings back by name instead of order. Based on that expectation, I hadn't really considered the plugin being a source for the issue.

That would definitely make sense though for how random the order of the lights keeps appearing from one scene to the next. Come to think it, I didn't notice any ML / emixer issues when doing test renders. It was only after I exported my scenes and then tried to batch network render them that it got kind of messy.
