Official tutorial redshift 04 rendering parameters

Progressive rendering is equivalent to IPR Interactive rendering

The rendering types that this method does not support temporarily are ：

1、SSS Subsurface scattering ;
2、 Photon mapping ;
3、Irradiance cache Radiation cache 、Irradiance point cloud Radiant point cloud
4、 Modify all parameters about the sampling quantity, such as ：Num samples 、 The depth of field 、 Caustics 、 Motion blur, etc

Filter definition Box<Triangle<Gauss<Mitchell<Lanczos, Simple understanding is sharpening ;

The clearer you want, the larger the size of the corresponding filter （ Other renderer dimensions generally refer to radius ,RS Is the diameter , So sometimes you need to turn on a larger value to get the desired effect ）, as follows ：

What is commonly used is ：Gauss：2-2.5-3 Mitchell：3-4-5

Overlay sampling , Convenient without setting one by one , You can control the lights in the scene , Reflection , Sample values such as refraction ;

Motion blur ： Use with the shutter of the camera ：

Environmental Science ： You can add HDR Environment or add solar physical light ;
Large aerosol ： It can make light fog effect and environment fog ; If you want to turn on the light fog effect, you need to give a little value to the volume fog under the light ;



Bokeh Simulate depth of field effect ;

Lens Distortion： Lens distortion , It is usually done later , Rendering is not often used ;
