FStorm Color Management

[gvman]

First of all: FStorm is great. I love it.

But I'm very confused with the Color Management of FStorm. My workflow tipically is the next: make a plane and a Sky object (Environment) with one solid white color. If the color is the same in the material editor (or color selector) and in the render view then I made everything well.



I came from C4D and I'm new in Max. Whatever I did in FStorm only the HDR lighting improved. Here is little comparison between Cinema 4D and Arnold and FStorm. Everything should look like the same but it didn't. It is a simple scene without tonemapping or anything else.

I uploaded the whole 3dsmax scene file. You can download from here: https://www.dropbox.com/s/vjf1wnfas3...torm_scene.zip

I appreciate all the help. I really want to use this great renderer. Thanks.

Think your gamma is set to 1.0 in C4D, and 2.2 in Max.

For me, colors looks correct. See pic.

[gvman]

No, it's 2.2 in C4D too. I used the same colors in Arnold and FStorm but the results is different. And I don't know why. Currently I'm out of ideas.

I made an image sample. I know it's because 2.2 Gamma of Max. But how can I choose exactly RGB (150, 150, 150) or anything else?

I wrote you a script with which you can see Color Matching based on the Gamma you want. Enjoy.

In your case to get 150,150,150 in 2.2 set color to 79,79,79 :

Fantastic little script Sylk!

And now it looks like your Arnold pic

Thank you for your time and for your kindness. It's fantastic. Thank you again Sylk!

[Sylk]

It was a pleasure

[mitviz]

so what was the real issue?

[Sylk]

No real issue, it's a normal working. With a Gamma to 2.2 a color looks washed out to screen compared gamma 1.0. Need to compensate the color code to show the same apparent color than gamma 1.0

If you are lazy just save a 4x4px pic with the color and use a bitmap. Gamma gets corrected by default.

i usually do things this way to reuse in different scenes of a color pallet cropped from photohsop or something
