NoiseTex

uniform sampler2D noisetex;

This buffer stores a generated RGB white noise texture. The texture is always square, meaning its width and height are equal.

Writing

This buffer cannot be written to. It can, however, be replaced with a custom noise texture from an image file or raw buffer data.

Size

The resolution of this texture defaults to 256x256. This can be configured with the noiseTextureResolution constant.

Format / precision

This buffer uses the RGB8 format. This cannot be configured.

Clearing

This buffer clears to random white noise data, or (if overwritten) the custom texture.

Flipping

This buffer does not flip.

Custom noise texture

Similar to custom textures, the noisetex texture can be overwritten with an image file from the shader files. The following line can be placed in shaders.properties, where <path> is replaced with the file path of the image file relative to the shaders folder:

shaders.properties

texture.noise=<path>
