I know there are a lot of Poser Material room experts out there. I would appreciate some help.

I'm trying to get a node set-up that has streaks of varying color (my current interest is shades of gray) that run in either vertical or horizontal lines. I have a lot of applications for this, but an obvious one is to add this to a vertical hair color image map to add some variance in the shades of color in the existing bitmap. I'd like to vary the width of the streaks and do this somewhat randomly.

I can kind of show you want I'm talking about by looking at the attached image. I've used the tile node to make vertical streaks. I then add this (multiply actually) to the existing hair image to yield streaks. The trouble is I can't randomly vary the streaks in terms of width or color so the pattern repeats. I think if there was a random number generator node, that might work.

I hope this is clear....

 

Thanks
