Changing RGB values in shake?

[Ajax]

Hi All,

Is there a way to change RGB values within the color tab settings? I set the color range to 0-255 then try to manually change the settings and nothing happens. I’m trying to maintain accurate colors from one app to another. Cheers, for any assistance! 😳

Hi,
which tab do you mean? Are you trying to change the color of your material, or do you want to change the apps’ settings in general?

I am trying to change lets say (a color node), however I want to keep the same RGB values as I do in lets say (photoshop). So I want to use 0-255 colors and transfer the numeric values to shake. I hope that makes sense, and thanks for the reply.

Hi again,
… now I get what you are trying to do. You want to keep working with values from 0-255 instead of 0-1 or so. Maybe creating a set of “local variables” might help. Unfortunately I am not that great in these things (yet) to help you out with the perfect formula ( if there is one..) Try asking at highend2d.com’s shake-forum,too.
– and tell us how you did it in the end.

This has been the response so far, and I think I figured it out once I expanded the color values tab and saw the seperate RGB values:

If you need to enter RGB values in a 0-255 basis, you can simply write your desired value and divide it by 255.

For example:
You need to input 180 for Red channel, 100 for green and 200 for blue.
Just enter these values in the RGB boxes…
R: 180/255
G: 100/255
B: 200/255

Hope that helps.

Thank you for your help! 🙂

I guess, that is it. but wouldnt it be 256? For 8 bit?

I tried it with a 50 gray color in a PS RGB image…

…Not sure, I think its just easier to just expand the Color node settings and then under the “L” tab expand it as well and you will see the seperate channels to manipulate.

well, I meant 50% gray color in my earlier post. 50% gray makes a value of 128 in Photoshop. In shake dividing 128/256 makes a perfekt 0.5.
Also there are 256 possible values from 0-255.
I’d give it a try.
