本文主要是介绍arnold材质贴图高光闪烁噪点的减弱方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1、arnold官方帮助pdf文档中对高光噪点的解决方案如下：
Noise can also appear on the specular highlights of thin geometry that use a shader with a high specular_weight value. Increasing the number of
Camera (AA) samples can help reduce this effect to a point. However, even with high Camera (AA) samples, anti-aliasing artifacts can appear.
Increasing the specular_roughness value helps to reduce this type of noise. Increasing the size of the light and reducing its intensity can also help in
these situations.
Specular Roughness: 0.2 Specular Roughness: 0.5
2、全局渲染选项，启用自适应采样，adaptive sampling 为 5-6 ， 8为电影，一般6就足够了，默认采样可以保持 3 2 2 2 2 2的基本低配，由于自适应，可以动态智能采样，不但减少闪烁，还会增加渲染速度。对于渲染大图较好。
3、减少高光闪烁，还没启用，全局的采样限制框架。可以抑制特殊的全局和高光过曝。
南无阿弥陀佛
