2. Let's look at motion blur first. There are three options to open, namely, off, composition setting and on. Off means that motion blur is not applied, while composition setting and on means that motion blur is turned on, as shown in the following figure:
3. Let's look at the shutter angle, which affects the blur intensity. It can be seen that the larger the value, the stronger the blur, as shown below:
4. Then look at the shutter phase, which refers to the opening angle of motion blur and the direction of motion blur. You have to set more effects yourself, and then look at the types, which are divided into linear and sub-frame sampling. Both of them are sampling methods of particle motion blur. The former is relatively simple, and it is determined by comprehensively considering various factors of particles, as shown in the following figure:
5. This level should be used together with the subframe sampling mentioned above. The larger the value, the greater the particle blur, as shown in the following figure:
6. Let's look at the progress of opacity. This means that the transparency of particles is reduced due to motion blur, and the transparency of particles is compensated, as shown in the following figure:
7. Let's look at neglect again. After opening, you can see whether there is a physical time factor (PTF), camera motion, camera motion & PTF, which does not need to eliminate the blur caused by particle motion in any way. Physical time factor (PTF) means that particles do not need to move when they are frozen, and camera motion means that camera motion does not need to produce the blur caused by camera. PTF means that the ambiguity caused by the above two methods is unnecessary.
8. Finally, look at the rendering mode. When you open it, you will see motion preview, full rendering, full rendering +DOF squared (AE) and full rendering +DOF smoothing. The above is the way of particle rendering, and you can set it according to your own needs.
