3ds max vs Maya color swatch
show user profile  9krausec
Does anyone know why Maya's color swatch generates such drastically different results than 3ds max's color swatch? I cannot seem to figure this out.

3ds max RGB / HSV colors are worlds apart from Mayas. Thanks for any insight. This has always bugged me. Thanks.

just a thought, one of them may be in linear space.

I've not done any comparisons, but that would be my first guess. I think Max has the more extensive color space adjustments, so maybe look there to make them equal (if possible?)

screenshots or it didnt happen! :D

I think Error404 is onto something there, ive noticed since max's forced 2.2 input/output the value bar is crunched in 3dsmax since 2014. I cbf id try figure out how to reverse it as I prefer a 'linear' value range - instead of a 2.2 sRGB workflow... which is currently what is labelled 'linear workflow'... (my ass - que the hate mail in 3,2,1...) In Corona you have to use the 2.2 srgb workflow.

Image 2 - "Linear Workflow" with the LUT turned OFF



These days just to cover myself I use actual jpg swatches - as I know the value is correct with a balanced lighting scene - I mentioned this earlier in my blog post about colour matching and linear workflow... u can look it up if you are interested.

Id be very interested to see what your on screen color dialogues look like

I'll post up my on screen dialogs tomorrow. Sort of odd that 3ds and Maya operate on a different color space like this. Makes things a bit harder when operations aren't consistent between two primary software packages like this.

I'll take a peak at your blog too. Thank you both.

in maya, if you're in linear workflow, you need to add "gamma correct" node to all your color slots, and from there adjust your color, otherwise you'd get wrong colors

P.S. and then you need to add the value of .455 to each color channel in "gamma correct" node.
P.S2 Vray might have its own way of setting up the the color slots to read in linear workflow

Color map linear multiply
Adaptation only
Affect swatches on
Vray gamma correction on all 8bit file nodes not already corrected
Gamma node .455, .455, .455 to generate all swatch color

Got everything running great I just was curious why the difference between Maya and Max. I'll do some more research and I have yet to review the blog mentioned in this thread.

There must be a better way, I can see Maya's colour swatch is displaying colours in linear 1.0 space. This is why you need a gamma node, this seems like a horrible way of doing things.

Hmm, you will probably think this is crazy but try it see if it works (if you want)...

Leave all the settings as default, put in the colour value like normal without a gamma node, in vray settings switch linear workflow on...

The only reason I say this is it looks like maya has the LUT off by default, you can work in linear 1.0 space and do your colours like normal, switching on linear workflow will do a .455 flip conversion at render - keeping everything linear with enabling the sRGB button in vray should display it as the exr will when its output.

Let me know how that goes if you dare :D

Tick the Linear work flow option? Are you mad? You must be bat shit crazy! Haha. I'll give it a go.

This is how I setup Maya Vray for LWF now-

Posted back in 2014 so it might be out of date, but that's how I normally go about it.

I'll give your suggestion a go today and read that damn blog finally.

Cheers.
