Maya File - Everything is Green, Missing Objects

hueyang

I have been working on a concept gun for the past couple of days and have been saving often. However, when I reopened my most recent file, I everything became green and I ended up losing a ton of work. This is the first time that this has happened to me and I have no idea where to go from here. Any help would be super appreciated..

here is a link to my file:

green is the indicator for missing shader...
this could happen if you dont load the render engine plugin... or if maya is loosing the connection just fo fun...

reassigning the shader should help... sometimes you need to assign the labert1 shader first and than the right one...
or resetting the viewport --> ogs -reset

My objects are totally missing from the outliner as well. When i go to Display > show all, they dont show either...
i reapplied the shader, and that fixes the green, but no luck on the missing objects.

When things like this happen, you'll want to check the script editor for errors. In your case some UVs got corrupted, which gave this error: "Invalid use of Maya object "ind"". Maya still doesn't recover from this error, so the rest of the scene gets borked on load.

Having a .ma file made this an easy fix, you can open this in notepad++ or whatever and search for "-nan(ind)" and replace all instances with 0.0. I happen to know that it's -nan(ind) from experience, but enough searching would have gotten you to these lines eventually. Nan is short for Not A Number, meaning maya tried to write a number out of range.

Usually we see this when someone has a very long construction history, but you're working cleanly here- so just some random hiccup. I didn't check everything after fixing, but the problem started with alternator_base. I'd take care to clean that piece well, and do an Optimize Scene Size, there are a number of probably garbage "rebuildSurface" nodes, a couple of them are somehow attached to that part.

@Dharma as @throttlekitty already said, just open your .ma file with any text editor and replace all "-nan(ind)" with 0. I tried this on your file and it worked.

One of the workarounds i use when objects turn green usually when i Undo boolean operations or/and when it seems like the shader is assigned (check in Attribute Editor and Hypershade) and reassign does nothing. I go in Hypersahde, graph material on green object and then just disconnect from its SG node then reconect it back into SG.
