resolution property
Vector3
resolution
getter/setter pair
Probe count along each axis. The product is the probe count and drives the atlas size. Aim for roughly one probe every 2 to 3 world units.
Denser is not better. A dense grid localizes each probe's influence and starts to reveal the grid structure, so reach for shadowBias and visibility before raising this. Values are clamped so the atlas fits a portable texture dimension.
Implementation
Vector3 resolution = Vector3(16, 8, 16);
