SD Toolbox 19

A free Substance 3D Designer node library (.sbs) of 15 grayscale utility nodes for procedural texturing: flood fill shortcuts, shape cutting, mask generators (curvature, slope, edge wear, dirt, leaks), and blend and transform helpers. Built in 2019, published in 2026 as an archive: cleaned up and documented, not maintained.

It uses only the stock library, with no bitmaps. Every node has a library icon, a description and documented parameters.

Tools: 15 Substance Designer nodes

	Tool	Does
	Flood Fill
	QuickFlood	Flood fill in one node: Size, Gradient and 2 Random maps, gaps filled
	Dilate	Grows each shape's value into the black gaps around it
	Mask: Size	Keeps the largest or smallest shapes
	Mask: Random	Keeps a random share of the shapes
	Shape
	Cut Simple	Cuts every shape along a random line
	Sharp Warp	Chips straight edges into sharp breaks
	Fillet	Rounds the shapes' corners
	Tips	Isolates the inner and/or outer tips of the shapes
	Masks and Patterns
	Mask: Lazy	10 masks from a height map: curvature, slopes, wear, dirt, leaks, sun bleach
	Compose	Keeps a pattern only inside large enough shapes
	Custom Cells	Turns a shape pattern into bevelled cells
	Blend and Utility
	Combine	Add / subtract through a mask
	Multiply	Multiply through a mask
	Transform	Transform 2D with tile X / Y / both toggles
	Lazy Curves	9 preset contrast curves

Most flood-fill tools start with a Clear Input step (a Histogram Scan, Position / Contrast) that turns a soft mask into clean shapes. Every parameter and output has a description in Designer.
