A collection of procedural textures for a Victorian house created in Substance Designer. The amount of wear and chipped paint are editable parameters within Substance Designer.

For the shingles, figuring out a way off adding varied water staining along the bottom of each tile was a challenge, since the shingles aren't arranged in clean rows. I ended up layering a noise mask over the base pattern and crushing out the darker half of the shingle with a histogram scan, leaving a nice pattern of wear along the bottom half.

In a similar vein isolating just the outer edges of the rounded tile siding was also an interesting challenge. I warped the outline of the tiles to get the chipping paint effect, then offset a clean version of the outline to mask all but a thin line along the edge. To really sell the slightly worn look I added a few extra scratches on the inner paint to simulate splintered wood.

I used a slightly different process to isolate the paint wear along the bottom edge of the siding (the most realistic place for paint chipping to occur). To get this effect I used a bevel node to highlight just the outer edges of each plank, then used a histogram scan to crush out all but a narrow strip and a directional blur to remove any vertical lines.
