Sorry Ulco, I misunderstood reply 109 obviously.
QuoteI'm afraid it wouldn't work for a building where one part (say all walls) exceeds the UV area. That whole section would have to be within the UV space, or you get tiling of the dirt painted in that UV space as well. Dirt won't be on the right spot, except maybe in the UV area.
That's actually the point of this method. Having unwrapped parts exceeding the 0-1 space is what is
causing the tiling, as we know. So this method takes care of the tiling in TG exclusively while the
unwrapped map does not exceed the 0-1 space and is, thus, paintable.
Gradual dirt might be a problem, haven't tried all options. Although masking the surface layer -
what I did here - works with grey values iirc, doesn't it?. (my map here hasn't any, just b/w)
The only other way I know of is doing it in ZB - applying a tiling tex, converting to polypainting,
re-mapping and then drawing your dirt map - as mentioned elsewhere before.
Bobby - feel free to do so.
