Light Probes
************
While not strictly correct, all lighting that is not coming straight out
from a light object is considered as indirect lighting in EEVEE.
That means distant :term:`HDRI` lighting (or World) is considered as indirect lighting.
In EEVEE, indirect lighting is separated into two component: Diffuse and Specular.
Both have different needs and representation. For efficiency,
the diffuse indirect lighting data is precomputed on demand into a static lighting cache.
As of now the diffuse light cache is static and needs to be computed before rendering.
It cannot be updated per frame (unless via scripting).
This limitation is being worked on and will be removed in future versions.

Pool Size
Size of the irradiance pool, a bigger pool size allows for more irradiance grid in the scene,
but might not fit into GPU memory and decreases performance.
