Hint

Hint

IOR

GGX 分布一起，用于控制透射光的粗糙度。

Strength of the emitted light. A value of 1.0 will ensure that the object in the image has the exact same color as the Emission Color, i.e. make it 'shadeless'.

Alpha

## 属性¶

Microfacet distribution to use.

GGX

Is an approximation to physically-based volume scattering. Gives less blurry results than Cubic and Gaussian functions.
