I am still fairly new to Blender. Although I came from Lightwave there are still plenty of things I am figuring out.
This one seems like it should be pretty easy but I am not sure where to even start looking for my solution.
I am making a paint brush and I want the tip to be darker than the section near the metal ring holding the brush to the handle. I have used a color ramp to get my colors and a noise texture to spread the colors around. The texture coord node and mapping node let me stretch the colors along the brush to make streaks instead of splotches.
What I can't figure out is how do I get the dark color to appear near the tip more often and the light color to appear near the metal ring more often still giving a variety of colors but concentrated to the ends.
Any suggestions on what to try to do this?
Here is sort of what I am after. Not exact but gives the concept. See how the brush still has strands but the darker area is focused near the tip? I just want to weight the randomness to lean darker to the tip and lighter to the base.
THANK YOU FOR YOUR ADVICE!
UPDATE! Although the answer from Onyx wasn't quite enough, it set me on the path I needed to get mostly to where I wanted to be. I still have some tweaking but I have the basic concept now.
In short, I took two color ramp nodes and mixed them together. One had the noise I wanted and the other used the texture coord and mapping nodes to get the rotation. The two ramps are similar in color but not the same. There is a third color ramp off screen but it is only used for the bump map for the brush fibers and not relative to this rotating of the color mappings I was after.
Thanks for helping me on my way!
