阴影

Eevee uses Shadow Mapping techniques to properly shadow the light coming directly from light objects.

A shadow map is a texture that stores the nearest occluder from the light position. Eevee also filters the shadow maps in order to smooth out the pixelated appearance.

矩形尺寸

Size of the shadow cubemaps used to shadow Point, Area and Spot lights. Higher shadow map size will give higher precision and sharper shadows.

级联大小

级联阴影贴图 使用的一个级联的大小。仅适用于日光。

高位深

此选项有助于减少由于阴影贴图内浮点不精确而导致的一些伪影。此选项有效地将阴影贴图的内存使用量加倍，并减慢其更新速度。

柔和阴影

Randomize the shadow maps origin to create soft shadows. It needs a lot of samples to get rid of the banding.

光照阈值

灯对照明有贡献的最小光照量。此阈值未考虑光的形状，因此可能不适用于每种情况。Blender提供 灯光裁剪 选项，您可以在其中设置截止距离。

The influence distance is also used as shadow far clip distance, which might affect how shadows looks. This influence distance does not affect sun lights that still have a far clip distance.

Note

和cycles里的大光源打光不同，eevee软阴影的生成不是基于物理光线跟踪计算的。

Tip

A 512 px cubemap has 6 × 512 × 512 pixels in it. Tweaking the Size parameters can have a big impact on memory consumption and performance.
