DataShader

Setup Macros

At the top of the vertex() function, declare SETUP_DATA_VERTEX.

At the top of the fragment() function, declare SETUP_DATA_FRAGMENT.

Layer Variables

A DataShader can output up to 16 vec4 and 16 float values up the chain, using LAYER_OUT_TEX_* and LAYER_OUT_MASK_* variables. It can also read data from layers below using LAYER_BELOW_TEX_* and LAYER_BELOW_MASK_* variables.

Output Variables

Data variables written to the chain. Read by layers above with the matching LAYER_BELOW_* variable.

Input Variables

Data variables can read values from layers below.
