With the release of Reality Composer Pro in Xcode 15.2 Beta, I can't wait to see what types of nodes we can use for our shaders. However, the documentation for Reality Composer Pro doesn't seem to be published yet (at least I couldn't find a list of all the shaders we can use). So I'm creating my own list based on what the "new node" button (currently wip) provides
Below is a list of all shader nodes available in Reality Composer Pro, with a brief description provided in the New Node dropdown.
2D program
Cellular Noise 2D: 2D cellular noise generator.
Noise 2D: 2D Perlin noise generator.
Ramp 4 Corners: A four-point linear-valued ramp (gradient) generator.
Horizontal Ramp: A ramp (gradient) generator of linear values from left to right.
Vertical Ramp: A linear value ramp (gradient) generator from top to bottom.
Split Horizontal: Splits the mask from left to right at the specified U value.
Vertical Split: Splits the mask from top to bottom, at the specified V value.
Worley Noise 2D: 2D Worley noise generator.
2D texture
Image: A texture that references a 2D image file.
Tiled Image: Samples data from an image, offsets and tiles it in UV space.
2D Transform: A node that applies an affine transformation to a 2d input.
UV Textures: A MaterialX version of the USD UV texture reader.
3D program
Cellular Noise 3D: 3D cellular noise generator.
