200 Grunge, Damage & Decal Alpha Maps + Decal Tools

200 alpha masks at 512 x 512: grunge, dirt, scratches, cracks, rust, stains, leaks, splatter, edge wear and impact damage. THESE ARE MASKS, NOT TEXTURES The greyscale value is the alpha. White means affect this pixel fully, black means leave it alone. You bring the colour and the material; these decide where it lands. Feed them into a decal projector, a detail layer, a blend mask, a vertex-paint splat, a UI overlay, or the alpha input of any shader that takes one. TILING VERSUS DECAL 156 of the maps are seamless: they repeat in both directions with no visible seam, and ship with Wrap Repeat and mip maps on, because they are meant to be seen at distance. The other 44 are one-shot decals - an impact, a leak, a scorch, a frame of edge wear - and ship clamped and unmipped so their edges stay exactly where you put them. The documentation says which is which, map by map, with its measured coverage. EIGHT FAMILIES Grunge and dirt (34), Scratches and abrasion (28), Cracks and fractures (24), Rust and corrosion (22), Stains, leaks and drips (24), Splatter and spray (24), Edge wear and frames (22), Impact and damage (22). WHAT YOU GET - 200 masks, 512 x 512, 8-bit greyscale - A contact sheet per family, so you can pick one by eye instead of opening two hundred files - A showcase scene that pans across those sheets - Documentation with every map, its family, its coverage and whether it tiles BUILT WITH CODE, NOT PHOTOGRAPHED Every mask is generated: noise fields, fracture systems, erosion and drip simulations, written for this pack. Nothing is photographed, traced or image-generated, which is also why the tiling maps tile exactly rather than nearly.
