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 |
|---|---|
| Bitmap Lookup | Looks up a bitmap from past in UV coordinates through OpenImageIO. |
| Blackbody | Modulates a color between two Kelvin temperatures. |
| Candy | Creates random circles with random colors and a turnable bump output. Useful for random dots or candy sprinkles. |
| Checker | Creates a simple checkerboard. |
Color Key
|
Simple color key shader for rough green/blue screen keying. Can do simple edge cutoffs in UV space and apply a garbage mask if needed. |
| Composite | Alpha-composites one color over another. |
| Digits | Emulates a 7-segment display of numbers. Useful for debugging and showing numbers in SME. |
| Falloff
|
Generates a value from white to black based on the angular falloff of the face normals. |
| Halftone Dots
|
Halftone dots that work well with toon shaders. |
| Lift/Gamma/Gain | Simple lift/gamma/gain color modifier. |
| Mandelbrot | Generates 4D mandelbrot/julia set. |
| 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. |
| Randomized Bitmaps | Randomly places (and alpha blends) a set of bitmaps on top of something else. |
| Rivets | Adds rivets along the edges of UV space in 1x1 squares. Squares can be bent for unevenness. |
| Simple Gradient
|
Generates gradient with six inputs. Code can be edited to add more inputs if required. |
| Simple Tiles
|
Generates various types of tiling. The Tiling Offset modifies the base parameter of the layout and can generate different effects. |
| Threads
|
Generates threads on a bolt. Apply as a bump or displacement to a cylinder. |
| Toon Width
|
Toon Edge Width is based on how close the surface normal when converted to screen space is to the given direction. |
| UberBitmap | Loads a bitmap via OpenImageIO. Includes UVW channels and transforms in a monolithic version. |
| Waveform (animated)
|
Generates various animated waveforms. The output wave is the raw value of the waveform, and an interpretation between the two colors. |
| WaveLength | Modulates a color between two wavelengths of light. |
| Weave
|
Generates a simple threaded weave. Useful for everything from cloth to carbon fiber. |
