It's an Photoshop Action that will convert every bright part (shine) of a image into adjustable green.
If you use this it will save you a lot of time when doing your control maps.
How it Works
Actions are made in the following in order:
- Convert Bright to a Green-tone;
- Adjust the Levels in order to invert the Neutral parts;
- Decrease Saturation to make it all Grey;
- Apply a Green Mask over the Desatured Shine;
- Adjust the amount of Green overall;
At the end, I put by default to show the Level dialog where you can rebalance the green levels, I recommend to not let it as it is.
Depending on the amount of bright of the texture, it would use a lot of green (Around ~240), and if you let it so, the control will have a strong effect on the result.
Unless that's your point, of course!
As it will attempt to convert white to green, I did my best to avoid Magenta-tones. So there is no "left-overs".
Magenta is the opposite color of Green, a bad conversion would result in some Magenta hidden between the Green.
So, if you remove the Green levels it would left you with some Magenta.
And, in terms of texturing is a bad thing, since engines look at Magenta-tone as it is part of Red-tone.
Each texture will require a certain rebalance on the default result.
So, don't forget to make your own defaults for the texture you are going to use it on.
How to Install
Just open the action file .ATN with Adobe Photoshop and it will install itself.
You, then, can use the shortcut F12, or open the Actions tab and play the action group.
You can also define a default for the green level by double clicking the level line of the action, make your changes, and click Ok.
And if you tick the dialog icon, the dialog will not show as you play the action.
