I have just recently learned about working linearly, and I'm just wondering how relevant this tool still is. I am using 2013 and 2014, and I guess the only issue with these versions is the colour swatches, since we now have the colour management input and output profiles for textures and stuff. So basically I am asking is this tool still useful in 2013/14 for gamma correcting maya's swatches?

edit: maybe it would have been good to read some of the posts before posting. sounds like you just updated it, but my question still stands, is it only useful for maya's swatches now?

For the most part. Depends on how you like to work. If you want to use Maya's color management then yes, you put it in 'color swatches only' mode and use it to automate the correction of all the swatches maya's color management won't correct.

Hope that helps.

Doh! You're right. It did not used to do this but I was mucking around in parts I hadn't touched in a while, bad idea usually. One simple little mistake broke it. lol.

Thanks for pointing it out! I'll check on the Vray issue as well.

Updated to v2.1.2

Fixed the bug Hamburger pointed out that would double correct gamma nodes.

I'll give it a crack and report back if anything else pops up. Good script. Thanks again.

Been using it for a few days and aside from that double correcting bug, everything seems great. Thanks for making this!

Not a problem. That should be fixed now. Didn't used to do that. Temporary bug I introduced changing the way a couple things worked.

Let me know if you notice anything else.

Not a problem. Glad it's helped you out!

Still need to check on the vray thing. I don't have it installed anymore. I'll have to go get the trial again. Is that still happening for you? Seems to work with the mia just fine.

Thumbs up

Hey man,

I just started to tackle the whole linear workflow bit in Maya 2014 and I ended up here after some research on making my life easier while gamma correcting everything.

So, first of all, thanks a lot! I tried it whilst half way through doing everything manually on my project, and I was doing exactly the same thing, which I guess is not surprising. I do have a couple of questions/ideas for you:

1) I see that the script doesn't apply the gamma correction node if values are == 1 && == 0. Does it have some kind of threshold(as in: ignore if value >= 0,995) or is it simply for full integers?

2) While doing it by hand, for the sake of full control I added a multiply divide node with this settings:
Mode = divide
Input 1 = 1,1,1
Input 2 = 2.2, 2.2, 2.2
Then I linked the output to each gamma node's gamma input. If you do this you can always revert to uncorrected gamma swatches by simply editing the multiplyDivide node.
If you added this, it would be really appreciated

Cheerio and thanks again!
