Color Correction

[rohit.gonsalves]

Hi,

I have a workflow over unigine.  I need to implement the color correction for my nodes which may take textures from Video, Media or graphics from HDD. and I see that there exists wonderful color correction parameters in Unigine Settings.

For basic implementation I am using this http://www.graficaobscura.com/matrix/

But I like to add White balance and I prefer all this implementation to behave exactly like Unigine color correction. I didn't find any post material or screen space shader for this.

Any clue?

Hello Rohit,

White balance is not exposed as a customizable feature.

If you need your own implementation, you'll have to write something over the top of the engine.

Thanks.

Dear Morbid,

I thought so. Even changing White Balance as color is little problematic and not intuitive for layman users.

So I have decided to extend the color correction with color temperature. I used color temperature LUT for the same and it works good over chroma keyed Video once taken inside Unigine. Attached is the Color temperature LUT I have used for the range 1000K to 40000K.

Thanks for reply.
