[TM2/SM/QM] Color grading usage (Mediatracker)

[Macgta]

Figured this would be the right place to post this; Couldn't find anything about it in patch notes, Just noticed it today. Is there any documentation on how this works? In the block preferences it asks to specify an image, Which is presumably an RGB lookup table of some sort. I've tried using different examples/types of lookup tables and nothing appears to have changed (I've also tried some 16x16 and 32x32 images of just red and green to see if it effects anything). Is this feature even implemented in Mediatracker yet? I've noticed a few other effects that seem to do nothing as well.

Thanks for any help provided.

Bump ?

[Fix]

Some Color Grading samples will be provided in next update.
Basically it is:
-take a screenshot of the game,
-paste it in photoshop (or you favorite tool).
-paste as new layer the image Identity_16x16x16.png.

Then apply color/brightness/contrast/saturation/etc... global changes on the screenshot AND the identity layer.
Then save the modified identity image as a 24bits "NameOfYourColorGradingPreset".png in your Media\ColorGradings\ folder. (In photoshop it can be a "copy flattened" /paste in anotehr image /save as *png, or "crop around the identity layer"/flatten/save)
Launch maniaplanet, and in the colorgrading track choose your new preset.png.
voilà, you can fade in out from default to your preset.
