[REQUEST] specular map, overall gain/offset control
I need to be able to adjust the overall brightness of the specular maps, as of now I have to edit them in an outside program like photoshop. The current sliders are good for defining the shape of the specularity, but I would request an additional control to adjust the overall lightness/darkness of the final images.

Thank you for the suggestion.
It shouldn't be hard to implement an additional slider for that. I only need to know what exactly you mean by the overall lightness. A gamma slider?

I have implemented a new slider for the specularity brightness that will be included in build 0.5.
At the moment, it is very simple (simply adds/subtracts a fixed value to the overall brightness).
When referring to Photoshop's level adjustments. There are 5 values that can be adjusted: min, max and gamma of the input image, and min/max of the output image.
Now, with only one slider, there are two ways to implement the variable brightness, and I need to know which one would be better:

- simple add/subtract to the overall brightness with clipping at black and white values
- gamma adjustment (changing the curve and moving the values within the whole range without clipping)
