i just saw this new node in cycles brightness
how can this be used ?
an example would be nice here
and can this be used with image textyure and proc texture
thanks
It’s simply a set of color operations where you can either tint the image or texture to a different color, brighten/darken the colors, or increase/decrease the saturation of the colors.
It works the same way as HSV mode in the color wheel, hue moves the selection circle around the wheel, saturation moves it towards or away from the wheel’s center, and the values moves another selection circle up and down the greyscale picker towards white or black.
Oh, I thought you were talking about the HSL node, what you have is the brightness/contrast node. To make it real useful, you should have an image texture or a procedural texture connected to the color input rather than just having a solid color.
With that, the brightness parameter will move all the RGB values towards 1, so if it’s high enough, your texture will be solid white.
The contrast parameter will change the contrast in the colors, in that it will tighten or loosen the range between the brightest and darkest colors, it does this by darkening the darker end of the RGB scale and lightening the lighter end.
With enough contrast, the bright colors get washed out and the dark colors are completely black with little in between, whereas with an ultra-low contrast, it would be fairly close to what you would see if you took all the RGB values of all pixels and averaged them.
at the time of this older thread
i mean i was looking for this node!
and now we have it
and it does control brightness and contrast which is great and much easier to do now
but we need another node to better control the alpha value for proc texture !
cycles is moving on better and better !
thanks
