3ds max RGB color values are different from PS

[Anonymous]

Why 3ds max RGB color values are not matching with Photoshop RGB color value.

Kindly help me why its showing like this.

EX: 3ds RGB 197,31,63 gives pale pink color 
PS gives Red tone color but the RGB values are same.

uncheck ENABLE GAMMA AND LUT on your preferences

Which renderer are you using?

incredibly bad advice!  LEAVE THE ENABLE GAMMA CORRECTION LUT ENABLED!

then realize that, going the other way - from photoshop to 3ds max - you have to convert the color R G or B values.

you can reverse it too.

the forumula for correcting gamma for R G or B values is this: 255*((old/255)^2.2)

so "old" is the number from photoshop.

you can see in my screen shot that

199 converts to 147.78 (in 3ds max type in 148)

155 converts to 85.28 (in 3ds max type in 85)

122 converts to 50.36 (in 3ds max type in 50)

you just round up or down

i created a excel spreadsheet (open office calc will do it too and it's free)  see attached screen shot.

this is how i set a color in photoshop or match a color from photoshop to 3ds max.

also know that when you render in max, save the image as a 16bit Tiff file or 8 bit jpg file - but when you open it in photoshop, have photoshop assign sRGB color profile to it - because that's what most render engine approximate unless you specify something beyond that.  - note this does not necessarily apply to HDR images saved from 3ds max.

i've included another screen shot that shows you what to do with photoshop color settings - so that it prompts you to take action when you open an image that has no embedded profile (aka a render from 3ds max) or when there is a profile mis-match.  generally you want PS to have a working space of sRGB unless you're into photographs or something else that specifically works in another color space like aRGB.

in PS - you can use relative colormetric or perceptual for Conversion Options Intent.  I happen to have mine set to perceptual for now.

Thank you Ronel

Thank you so much for providing a detailed information. It's saved my lot of time and effort.

you are welcome!

in the case of vray 5.0  CPU rendering and GPU rendering here are two screen shots to find color management settings in the render settings.  and one showing the vray frame buffer color representation of the image.  all set to sRGB.

hi,

May I know where to type the number? Thanks!

[Mr.Mxyzptlk]

Thanks this is a great post. For those of us that are not versed in excel would you mind sharing your spreadsheet?

[domo.spaji]

Here's much more useful tip:

To sample/pick color anywhere in screen press and keep pressed LMB when leaving Max windows.

[Mr.Mxyzptlk]

What does holding the LMB down supposed to do exactly?

[domo.spaji]

Well, you can pick the color outside Max even without that but for continuous sampling and for averaging sampled colors (with press and holding Shift) outside Max windows we have to press and hold LMB before dragging elsewhere in the screen.

Or simply to keep Max in focus all the time.

hi i do not think this is the place where you are supposed to type in the number. It is done right in the material editor 🙂
