To define the look of our fur we'll want to play around with some more of the Fur Description Note attributes. I'll select the fur and go to the Fur Description node. And let's look at Curling, Scraggle, and Clumping. You'll notice that Base Curl and Tip Curl both have a value of 0.5. And with a value of 0.5 there's no curling. If we increase the Base Curls to value of one, then what you will see is that the base or root of the fur is bent, but the tip is straight.
Likewise If we increase the Tip Curl up to one, we will see that now the base is straight but the tip is curled. And if these values are less than 0.5, what will happen is the curl will go in the opposite direction. So, 0.5 is no curling. One is curling in one direction, and zero is curling in the other direction. And we can combine these, and we can get s curves and do all sorts of stuff. The amount of curvature is going to be determined by the number of segments down here.
Currently, we've got the default of ten segments. If I reduce the segments down, we will start to see it look a lot more blocky. And this might be a good thing to do for performance enhancement. If you've got fur that's in a shot where it's pretty far away from the camera and we can't really see individual fur hairs very well, then we might reduce the number of segments in order to get a faster render. Turn that back up to ten. Okay, I'll turn the Base Curl and Tip Curl back to 0.5 to neutralize that.
Next we'll look at Scraggle. And Scraggle is basically chaos, turbulence and noise. And as I increase that Scraggle amount you'll see we get very chaotic fur. The amount of Scraggle also interacts with the Scraggle Frequency and Scraggle Correlation. Scraggle frequency is the size of the noise. If I reduced the frequency we get a lower frequency noise or larger wavelength noise. And if I increase the frequency, we get more chaotic noise. Scraggle Correlation has to do with how fur hairs near one another will sort of assume the same scraggle shape.
And if I increase this Scraggle Correlation, what'll happen is nearby fur hairs will kind of assume similar scraggle shapes. It's a Scraggle Correlation. Alright, I'll turn the Scraggle back off again. And finally, let's look at Clumping. Clumping is the tendency of the tips of the fur hairs to stick to one another. And as I increase the clumping, at first we won't see much here because it doesn't really have a good frequency. If I increase that Clumping up a lot, it just kind of looks weird.
But if I reduce the Clumping Frequency, what we'll do is we'll have fewer and fewer clumps. So if I bring that frequency down to a lower value of, let's say, about ten or so, then the clumps will start to become more clear here. And additionally, we can play around with the Clump Shape which is going to control how those clumps stick together. With a negative value the clumps sort of come to a point here. We get these, sort of, concave shaped structures here.
With a positive clump shape the opposite happens, they kind of create these convex forms. Okay, so that's how we can adjust the look of the fur using Curling, Scraggle and Clumping.
