Buffer node¶
The Buffer node samples its input into a texture of a given resolution and outputs the result.
Buffers can be used either as inputs of complex nodes (to limit the combined shader’s complexity), or to create a cheap blur/pixelization effect (by using the LOD output). Note that many complex transforms that are provided in the nodes library already include buffers where necessary.

Inputs¶
The Buffer node has an input that will be stored into its buffer image.
Outputs¶
The Buffer node has 2 outputs:
the first output provides the image
the second output generates a given mipmap of the image
Parameters¶
The Buffer node has two parameters:
the texture resolution
the mipmap level of its second output
