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 tell Iris to generate a mipmap chain for a given shadowtex buffer. Each one 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.

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

Warning

These directives are currently bugged. Mipmap chains for shadowcolor buffers will not be generated. Mipmaps for shadowtex buffers work as intended.
