Practice process

Hello, Hello everyone , I'm Xiao Kong . The special effects series has not been updated for a long time , Today I will show you a particle effect - Venom spray The effect of .
Let's look at the renderings first

From the picture , Let's do a little analysis .

1. The venom and liquid just sprayed
2. Small dispersed liquid produced over time
3. Mist produced by liquid
4. Dust is generated after landing

It is divided into four parts . good , Now that I know , Then let's start to realize .

Venom big liquid

As shown in the figure , Create a particle object , We will Start life cycle Change it to 0.2-0.4, The starting size is changed to 0.03-0.06, Focus on adding the medium gravity modifier , To achieve the effect of falling in the process of liquid particles spraying , The number of particles produced per unit time in the emission module is set to 20 above .
At this time, the effect is like this

Prevent too many moving pictures and don't put them .
Then we continue to modify , Check Life cycle speed modular , Set it to the following value （ Double constant random value ）：

So what do these mean ？
Represents the linear velocity of the particle on the target axis ,x Random on axis 1 To negative 1 Between ,y The axis is 1 to 2 Between ,z The axis is 4-6 Between .

A positive number means that the particle moves in the positive direction of the target axis , A negative number means moving in the negative direction of the target axis . So how to better understand ？ Let's take a constant , Keep changing the value , Let's see the moving picture , Pay attention to the mouse adjustment value and coordinate axis

Only a constant representation plus a dynamic graph must be understood .

So double constant , It is randomly generated in this interval , And then realize the real sense of randomness , No longer regular .
next , Let's add Life cycle size Templates , With the passage of time , The liquid is getting bigger , After all, who comes up is big , Not all have to develop ？

It's not over yet. , We set the rendering mode in the rendering module to the second , That is, stretch Billboard, Stretch the length .

But look at the effect , Not ah , The particles stretch , Don't worry , We change the material into our own , Replace the map in the material with a long strip .

Pictured , One, two, three, four can be set in sequence , Careful, you must find , Rendering mode The length ratio in I will be positive 4 Revised to -4, ha-ha , That's because my mapping direction is reversed , This is positive . It's very witty .
Last , Let's add another color to it .

The most basic big liquid effect doesn't come out .

Let's talk about the rest in the next article , By the way , need unitypackage I can just ask for your direct private message . Nothing , Nothing .
Be bold , We will have a story ！！！
