The OSL category of shaders (maps) includes several general shaders as well as several subcategories.
Tip: When exploring OSL shaders, remember you can find a short description at the top of the interface.
| Shader name | Description |
|---|---|
| 4-point Gradient | Generates gradient based on 4 locations such as TopLeft, BottomRight, etc. |
| Advanced Wood | The implementation of the Advanced Wood map as an OSL shader. The representation in the viewport matches the render. |
| Bitmap Lookup | Looks up a bitmap from UV coordinates through OpenImageIO. Useful to lookup and load UDIM, with ability to see all textures in viewport. |
| Bitmap Random Tiling | Looks up a bitmap from UV coordinates and modifies each repetition so tiling is not evident. The shader has a mode to properly transform normal maps. It outputs the modified UV so it can be hooked up to other Bitmap Lookup shaders so you can apply the identical randomness, in addition, it outputs the Random Index itself to drive downstream synchronized modifications. |
| Color Correction | Multi-stage color correction, including channel remapping, hue-range limiting, and three-tone color tinting. |
| Curves (color) | Transforms an input using an arbitrary curve, that can be used for gradients or as a color correcting tool. |
| Curves (float) | Transforms an incoming float value to an outgoing value defined by a curve. |
| Lift/Gamma/Gain | Simple lift/gamma/gain color modifier. |
| Noise | Generates advances noise. |
| Noise (3D) | Generates more advanced noise in 3D, for color, vector, or individual component outputs. |
| Noise (Gabor) | Generates Gabor noise and exposes its specific options. |
 Organic Noise
|
Modulates and filters OSL noises to produce organic looking noises. Garden variety of caustic, fleshy and abstract noises. |
| Randomized Bitmaps | Randomly places (and alpha blends) a set of bitmaps on top of something else. |
| Simple Gradient | Generates gradient with six inputs. Code can be edited to add more inputs if required. |
| Tri-tone | Color corrects an input color using highlights/midtones/shadows. |
| Tweak/Levels | Tweaks a color. |
| UberBitmap | Loads a bitmap via OpenImageIO. Includes UVW channels and transforms in a monolithic version. |
| UberNoise | Adds complex types of noise such as Perlin, Fractal, Cell, fBm, and Worley. |
| Wireframe | Creates a wireframe with a fixed width relative to rendered pixels, with a square every 1x1 unit square in UV space.
Tip: Use with a UVW Map and set to 'Face Map' to get a classic wireframe look.
