WebIssues with the current Principled BSDF. MultiGGX is a headache - slower, noisier, has bugs, hard to maintain. No "proper" metallic Fresnel, just basic F0 control. Sheen is outdated and designed to fix a problem that no longer exists. Tint options are limited - if we're giving non-physical control for artistic tweaks, might as well do it properly. Web第三节，基于物理着色（三）- Disney和UE4的实现则是在以上的基础上谈谈Disney Principled BRDF的设计思路，参数意义，以及一些漂亮的渲染结果。 第四节，基于物理着色（四）- 次表面散射则简单介绍了次表面散射材质的相关理论以及算法。 那么现在首先说说漫反射。

In this study, we assume that we can integrate over a 5-degree half-angle cone, and this helps provide some additional smoothing of the results in addition to the smoothing that occurs from averaging the different incident positions and incident … community bank chatham ny
