I’ve added a picture to better describe what I’m trying to say, cos I don’t think I’m using the right terminology (which would explain why I’ve been unable to find any other examples or tutorials on this!)
If you look at the vert front of the nose, you can see there’s a few streaks of black ‘soot’ or something behind it, in streaks. And a lot of the panels on this have a (very faint) grey streaking effect too, from abrasion or from dust or whatever. And most ships / cars / etc would have this kind of thing, especially around exhausts.
My plan, so far, is to just add this on as a final layer using a graphics tablet and a brush. Cos it seemed like the easiest and most accurate way to do it. (And this is just an example, I pretty much mean this is my plan for any fine detailing like that, that isn’t a whole-face kind of texture).
However before I invest in a decent tablet and this kind of workflow, I thought I should ask if there’s actually a better / faster / easier workflow to do these kind of fading-out directional streak/leak effect. Using Mixer, ideally, as this is what I’m likely to be using going forward (along with blender of course, so blender options that are compatible are also fine).
