Decals-how to name them

Hi I am not so good to english, so I would like to ask you, how can I find decal textures(on google f.e.), which are created by rain under old windows or rusty metal parts: here s an image:

or can you post some links or images (very best with alpha) of that decals ???


Normally, stains like that gets done with image editing side. Just layer a stain over the wall image, process it, than stick that wall image on to a 3D face.

I better thinked of “how keywords” I should write to google to find that textures, coz the normal stain texture ( presented on full image) arent so realistic and there is a lot of work with them to get them to final texture like on upper image. has some good decals like the ones you are looking for.
