New Gamma Correction Tool!

#118

Yep - his method is good too! Nice, thanks a lot for even considering it.

Good stuff,

a radio button would be perfect, something like “brake connections”, sorry for the late answer, too busy as always :smiley:
thank you in advance

p.s.
for me the AO tool is just perfect, even without a fancy ui, it´s pretty useful :wink:

@Dagon: Right on. As soon as I can make room for some more script writing I will make that happen. Thanks for the feedback!

@nbreslow: I’ll upload the new version tonight. The crazy thing is I already implemented that behavior on my own local copy and just never uploaded it. I started having to do a bunch of sky shots with clouds and needed it to work with maya fluids. Sorry for the late posting…I’ve been slammed with other work and it slipped my mind!

No worries! Whenever you get a chance, totally understand. I have been going through the Gnomon Intro to Fluid Effects DVD in my spare time and really like some of the results I have gotten. I anticipate having to use Fluids more at work so your gamma tool is right on time. :slight_smile: Thanks again, will check back.

#122

Changes:

  1. Added support for maya fluids.
  2. Fixed mip_gamma_gain to be classified as a utility.

As always, run it on a test scene first to make sure no new bugs were introduced in the process. I tested it on my end…but better safe than sorry. :slight_smile:

Many thanks Justin! Just downloaded and working fine, going to test it further later today. Best gamma correction tool out there, you’re the man!

DELETED: not relevant and possibly waffle!

Reflectivity just a multiplier of reflective colour?

#125

justin, it seems the script will not do anything if i make changes to the default color swatches then run your script. so is it an error or i should have make any adjustment after i executed the script ?

#126

Hmmmm…are you saying that if you change the color of one of the color swatches from the default color to a different color, say blue, then the script will not work? Or are you saying that after you run the script you can no longer make changes to the default color swatch?

#127

Thanks so much for writing this amazing script! I’ve been promoting it for awhile now. :thumbsup:

#128

Not a problem. :slight_smile: Glad it’s been helping out. Hard to believe that 2 years later we still need to use a script like this in Maya. When I first wrote it, I thought it would be rendered obsolete almost immediately by Maya’s color management system. Well…I see just how wrong I was about that and I’m glad now that I decided to write it anyways.

#129

Don’t want this to get locked just yet since there’s still a use for it. Plus I may have one more update in a little while and want to be able to let people here know about it. :slight_smile:

#130

thumbs up for an update :buttrock:

#131

Great tool - use it all the time. Updates are appreciated, thank you for maintaining this for us!

1.) Added support for MILA shaders.

Started doing basic tests where i only used color swatches and got tired of gamma correcting them real quick. lol.

I don’t think I introduced any bugs but I did go mucking around a bit so it’s possible. Let me know if you find any and I’ll get it fixed.

Thanks!

  1. Fixed a bug I introduced in v2.1 that wouldn’t update file textures anymore.

Anyone who downloaded the last one please re-download or your file textures won’t update. Sorry about that, don’t know how I missed that one. Was too hasty with my confidence in my edits. That’ll learn me. :slight_smile:

#134

Sweet tool man!

Although I notice two things.

  1. It didn’t seem to add a gammaCorrect node between a ramp shader and a vrayMtl (that was referenced into the scene).

  2. If you press the Update all shaders twice, the whole scene gets double gamma corrected. Maybe there is a way to already detect that a gammaCorrect node has been addded so it skips over? I’m not sure.

At any rate, great tool and thanks for sharing.

Thanks! Glad it’s helped out.

Interesting…that should work. I’ll test it this weekend.

This should definitely not be happening. I put checks in there to prevent that. Has not been doing that on my end. If I can reproduce the problem I can find out what’s wrong. But it’s not doing that on my end thus far.

#136

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?

#137

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.
