Modify nodes
Transform, filter, remap, and combine heightfield values.
15 nodes
Adjust
Brightness, contrast and gamma in one pass. The everyday shaping node — reach for this before wiring a Curve.
Autolevel
Rescales the value range to fill [0, 1]. The standard cleanup after a chain that has drifted off scale.
Blur
Softens a heightfield with a graph-space box blur.
Clamp
Holds values inside a range, optionally rescaling what survives back out to [0, 1].
Curve Remap
Remaps values through an editable monotone curve.
Distance
Builds a sloping heightfield from distance to a shape boundary. Useful for landmasses, ridges, clearings, and other masks.
Flip
Mirrors or transposes a field.
Invert
Flips values: out = 1 - in.
Math
Applies one arithmetic operation against a constant. The escape hatch for shaping a field without a dedicated node.
Median
Replaces each point with the median of its neighbourhood. Removes speckle and stray spikes without rounding off edges the way a blur does.
Range
Selects a band of values as a soft mask: 1 inside the range, falling off to 0 outside it. The mask node most Blend setups want.
Sharpen
Unsharp mask: adds back the detail a blur at this radius would remove. Recovers crispness lost to erosion or heavy smoothing.
Threshold
Outputs 1 where in >= threshold, else 0. Useful as a Blend mask.
Transform
Pans, scales and rotates a field in graph space. Areas pulled in from outside the map repeat, so a tiling generator stays seamless.
Warp
Displaces a field along a noise field, so straight features meander and repetitive noise stops reading as noise. The single biggest realism win available to a generator chain.
