First of all, let's talk about what an alpha is.…Alphas are used in all kinds of computer graphics software and it's simply a…grayscale image, a picture that uses a range of values from black to white.…What makes a grayscale image an alpha instead of just an ordinary picture is how it's used.…Different softwares can interpret these light and dark values as data rather…than as simply a picture.…An alpha could be used to define what parts of an image should be transparent;…white could be opaque and black could be see-through and every shade of gray…could be varying levels of opacity. Or an alpha could be used to define what…parts of a model should be shiny and which ones should be dull.…
As far as ZBrush goes, alphas are used to define what parts of a brushstroke…should get the full effect and which parts should remain unaffected.…So let's just test this out.…I am going to open up the DemoRhino, and let's change its color to something…lighter so it's easier to see.…I also want to make it more dense,…
