# Look for triple sharp ### comments - this is what I changed since the last step.

STEP 3

That was a good start. But, it's too blue, too low, and too big. Let's adjust.

clr = ImageMap(":Runtime:Textures:Poser 6 Textures:James_Face_Color.jpg")

apply to diffuse color of surface, also set soft specular

s = Surface(clr, 1, 1, .2, .5)

Less blue, more green, here.

bruiseclr = Color(.5, .3, .6)

Move cy up a bit

cx = .4
cy = .5

Going to use a simple circular pattern to blend in the bruise.

x = U - cx
y = V - cy

In r, I'm putting the distance from the cx cy position.

r = sqrt(x * x + y * y)

We'll put the range of the bruise in this variable, br.

.1 was too big

br = .06

Now I'll create the blender input using the Scale function.

A certain distance (br) from the center, the bruise is completely gone - this distance

goes in the second argument so that Scale produces 0 when r = br.

We'll make the bruise come full on at half the br distance, so br/2 goes in the third

argument - this tells the Scale when to produce a 1.

bruiseblender = Scale(r, br, br / 2)

#Finally I simpley blend the original Diffuse_Color (from above) with the bruise color
#using the bruiseblender I just calculated.

s.Diffuse_Color = Blend(s.Diffuse_Color, bruiseclr, bruiseblender)
