Shadow Mipmaps

Shadowtex

const bool generateShadowMipmap = true;

const bool shadowtexMipmap = true;

const bool shadowtex0Mipmap = true;

const bool shadowtex1Mipmap = true;

Location: any glsl file

These directives tells Iris to generate a mipmap chain for a shadowtex buffer. This directive only needs to be defined once in the shader pack, and can be defined in (mostly) any shader file. The mipmap will be generated after the shadow pass but before shadowcomp.

generateShadowMipmap will generate mipmaps for both shadowtex0 and shadowtex1, whereas shadowtexMipmap will generate mipmaps for only shadowtex0.

ShadowColor

const bool generateShadowColorMipmap = true;

const bool shadowcolor0Mipmap = true;

const bool shadowColor0Mipmap = true;

const bool shadowcolor1Mipmap = true;

const bool shadowColor1Mipmap = true;

Location: any glsl file

These directives tells Iris to generate a mipmap chain for a shadowcolor buffer. This directive only needs to be defined once in the shader pack, and can be defined in (mostly) any shader file. The mipmap will be generated after the shadow pass but before shadowcomp.

generateShadowColorMipmap will generate mipmaps for both shadowcolor0 and shadowcolor1.

WARNING:

this feature is currently bugged in Iris, no mipmaps for shadowcolor buffers will be generated, however mipmaps for shadowtex buffers work fine.
