Parameter reference

Hou-DisplacementX (COP)

Generator

Parameter	What it does
Seed	Decides where every shape lands. The same Seed with the same settings always gives the same map, at any resolution. Default 1; 0 to 1000.
New Seed	Picks a random Seed - the Generate button of the web version.
Iterations	How many shapes to draw. Each iteration draws one randomly picked shape type, so more iterations give a busier map. Cook time grows with Iterations times the pixel count. Default 100; 10 to 2000.
Background	The grey the canvas starts from, before any shape is drawn. Default 0.125; 0 to 1.
Resolution	Output size in pixels. Ignored when a layer is wired into the Size Reference input - the node then matches that layer instead. Default 2048 x 2048; 16 to 8192.
Resolution Menu	Picks a common square size for Resolution. You can still type any size into the fields.
Seamless	Wraps shapes that cross an edge around to the opposite edge, so the map tiles. Lines always span the whole image and are not affected. Default off.
Invert	Flips the height map: raised becomes recessed. Default off.
Randomize All	Rolls new random settings for everything, like the web version's Randomize all. Does not change Seed or Resolution.

Shapes

Rectangles, Grid, Columns, Rows and Lines each have their own folder with a header checkbox (Enable Rectangles, Enable Grid, and so on) and a Randomize button (Randomize Rectangles, Randomize Grid, and so on) that rerolls that shape's own settings without touching Seed. A shape type left off still takes its share of the iterations, so the others do not get denser.

Parameter	What it does
Brightness	Each shape gets a grey value picked between Min and Max. 0 is black, 1 is white; in height terms, low reads as recessed and high as raised. Default 0 to 1.
Opacity	Each shape gets an opacity picked between Min and Max. Lower values let the layers underneath show through. Rectangles default 0.5 to 1; the others default 0.8 to 1. Range 0 to 1.
Scale	Multiplies the size of every shape of that type. 1 matches the web version's 100%. Default 1; 0.2 to 2.
Amount (Grid, Columns, Rows only)	How many cells each shape draws, picked between Min and Max, separately per direction. Default 2 to 5; 1 to 10.
Gap (Grid, Columns, Rows only)	Space between cells, as a multiple of the cell size. 1 leaves a gap as wide as a cell. Default 1; 0.1 to 10.
Width (Lines only)	Line thickness, as a fraction of the image size, picked between Min and Max. The web version's 5-10 is 0.002-0.004 here. Default 0.002 to 0.004; 0.0001 to 0.05.

Sprites

Parameter	What it does
Enable Sprites	Stamps sci-fi panel sprites from the packs below. Off by default, as in the web version.
Classic	Includes the Classic pack. With several packs on, each sprite is picked from all of them at once. Default on.
Big Data	Includes the Big Data pack. Default off.
Aggromaxx	Includes the Aggromaxx pack. Default off.
Crap Pack	Includes the Crap Pack. Default off.
Rotate	Turns each sprite by a random multiple of 90 degrees. As in the web version, the turn is about the image centre, so it moves the sprite as well as turning it. Default on.
Randomize Sprites	Picks random packs and a random Rotate setting.

Blend Modes

Sixteen toggles - Color Burn, Color Dodge, Darken, Difference, Exclusion, Hard Light, Lighten, Lighter (Add), Luminosity, Multiply, Overlay, Screen, Soft Light, Source Atop, Normal, XOR - each allowing that blend mode. Every shape picks one of the ticked modes at random; with none ticked, every shape uses Normal. Normal is the only one on by default. Randomize Blend Modes ticks a random set.

Outputs

Parameter	What it does
Normal Strength	How steep the normal output reads the height map. Higher values give harder, more pronounced edges. Default 1; 0 to 10.
Color Gradient	Maps the height map to colour for the basecolor output: the left end colours black, the right end colours white.

Hou-DisplacementX Heightfield (SOP)

Output

Parameter	What it does
Output	What the node outputs. Heightfield: with nothing wired, the height layer as a heightfield (height and mask volumes); with geometry wired, that geometry displaced. All Layers: adds the normal, basecolor and id layers as volumes, or, when displacing, writes Cd and displacementx_id onto the points.
Show Color	Shows the Color Gradient in the viewport. On a heightfield it assigns a HeightField Visualize material mapping the gradient over 0 to Height Scale; on displaced geometry it writes Cd onto the points. Off by default - the material replaces any material already on the heightfield.

Heightfield

Parameter	What it does
Size	The heightfield's width in scene units. The other side follows the aspect of Resolution. 1000 matches the HeightField SOP's default, so erosion and other scale-dependent tools behave as they do on a fresh heightfield. Voxel spacing is Size divided by Resolution. Not used when geometry is wired. Default 1000; 1 to 5000.
Height Scale	How tall a full-white pixel stands, in scene units. The height layer runs from 0 to 1, so this is the height of the tallest panel. Not used when geometry is wired. Default 50; 0 to 500.

Displace Input

Parameter	What it does
Tile Size	How big one repeat of the map is on the object, in scene units. Smaller tiles the map more often. While geometry is wired, Seamless is always on, so the repeats meet without a seam. Default 2; 0.001 to 20.
Tile Offset	Slides the projection over the object, in scene units. Default 0, 0, 0; 0 to 10.
Blend Sharpness	How crisply the three projections (along X, Y and Z) hand over to each other where the surface turns. Low values blend them over a wide band; high values make short, sharp transitions. Default 4; 1 to 16.
Displace Amount	How far a full-white pixel pushes the surface out along its normal, in scene units. Displacement only moves the points that are there, so the geometry needs to be dense - Subdivide or Remesh it first. Default 0.1; 0 to 1.
Midpoint	The grey that stays on the surface. 0 pushes everything outward; 0.5 pushes light areas out and dark areas in. Default 0; 0 to 1.

Every Generator, Shapes, Sprites, Blend Modes and Outputs control listed above for the COP node is also present on the Heightfield node, under the same label, and works the same way.

Version signals

Every jvtools node carries these at the bottom of its parameter list:

Parameter	What it does
Current Version	The product version of the asset you have installed.
(update notice)	Appears when a newer version is available on the store.
