3ds Max烟雾效果——浓烟雾

大家好! 在这里,我有一个创建浓烟雾效果的教程,可以用于像油或爆炸烟雾,火山喷发,森林火灾等等。 你可能已经在互联网或电视,或有时在你的现实生活中看到这种烟雾,但它并不是每次都发生。

Hello everyone! Here I've got a tutorial for creating a thick smoke effect, which can be used for such things as oil or explosion smoke, a volcanic eruption, a forest fire, and so on. You may have seen this kind of smoke on the internet or on television, or sometimes in your real life, but it doesn't happen every time.

There are number of software packages and plugins with which you can create fire and smoke effects, such as FumeFX and Phoenix FD for 3ds Max and Maya, Houdini, Cinema 4D and so on, but many big VFX and animation studios use FumeFX in their pipeline as it's well-established, trustworthy and most importantly user-friendly. There are different techniques you can use to make this effect in FumeFX, such as Simple Source, Object Source and Particle Source, but we are going to use Object Source.

有许多软件包和插件,您可以使用它们创建火和烟的效果,如用于3ds Max和Maya,Houdini,Cinema 4D等的FumeFX和Phoenix FD,但是许多大VFX和动画工作室在他们的管道中使用FumeFX因为它已经建立,值得信赖,最重要的是人性化。有一些不同的技术可以用来在FumeFX中产生这种效果,例如Simple Source,Object Source和Particle Source,但是我们要使用Object Source。

 

Before you start working on this kind of effect, it helps to have good knowledge of fire and smoke properties, such as Turbulence, Velocity and Buoyancy. There are different types of smoke, from thin smoke for incense and cigarettes, to thick oil smoke or explosion smoke, and each one has different properties.

在开始处理这种效果之前,它有助于了解火灾和烟雾属性,例如湍流,速度和浮力。有不同类型的烟,从薄香烟和香烟,到厚油烟或爆炸烟,每个都有不同的性质。

 

I can't teach you each and every parameter of this plugin and software, as they're very vast and need a lot of time to go through, but this particular tutorial will cover as much as required to create this thick smoke effect. This is very interesting subject, because you can't define one certain process to create this effect. As much as you will use your creativity and tools available, you will find different types of effects every time. So it very much depends on your own understanding of how to use the tools and techniques.

我不能教你这个插件和软件的每一个参数,因为它们非常庞大,需要很多时间,但这个特定的教程将涵盖创建这种浓烟雾效果所需的多少。这是非常有趣的话题,因为你不能定义一个特定的过程来创建这个效果。尽可能使用你的创造力和工具,你会发现不同类型的效果。所以它非常取决于你自己对如何使用工具和技术的理解。

Step 01: Create an object
步骤01:创建一个对象

Open 3ds Max. Before we start working on our scene, remember that we are going to use the Object Source technique in FumeFX. This means we are going to use an object to emit smoke, so for that purpose we'll start by creating an object. We'll use a Plane.

打开3ds Max。 在我们开始工作之前,请记住我们将在FumeFX中使用对象源技术。 这意味着我们将使用一个对象来发射烟雾,所以为了这个目的,我们将从创建一个对象开始。 我们将使用平面。

Go to the Create panel and select Geometry > Standard Primitives > Plane. Now change the parameters to the following: Length: 40, Width: 40, Length Segments: 50, and Width Segments: 50. Set the Position to X: 90, Y: 00 and Z: 15.

转到创建面板,选择几何>标准基元>平面。 现在将参数更改为以下参数:长度:40,宽度:40,长度段:50,宽度段:50.将位置设置为X:90,Y:00和Z:15。

Step 02: Modify the object

After creating the Plane, it's time to modify it by adding a Noise Modifier. Select the Plane, go to the Modify panel and select Noise Modifier. Now make the following changes: Scale: 3.0, Strength X: 12.5, Y: 12.5 and Z: 25. Now go to the Animation section and turn on Animate Noise, then set the Frequency to 3.0. Now you can see the Plane with animated noise applied, and you're ready to use it as fire and smoke emitter.

步骤02:修改对象

创建平面后,是时候通过添加一个噪声修改器来修改它。 选择平面,转到修改面板,选择噪声修正器。 现在进行以下更改:缩放:3.0,强度X:12.5,Y:12.5和Z:25.现在转到动画部分,打开Animate Noise,然后将Frequency设置为3.0。 现在你可以看到平面的动画噪声应用,你准备使用它作为火和烟雾发射器。

Step 03: Create a FumeFX Object Source

After finishing the modeling and modification of our object, it's time to proceed to the FumeFX plugin. So first of all we will create the FumeFX Object Source where we will add our Object. To create a FumeFX Object Source, go to Create Panel > Helpers > FumeFX > Object Src. Click on this button and drag it into the viewport. Now go to the Modify panel to make some changes in the Parameters. Change the Object Src Type to Solid. Set the Smoke to 25.0, then go to the Velocity section and set Object's to 5.0 and Extra to 15.0. Keep the other parameters as they are.

步骤03:创建FumeFX对象源

完成我们的对象的建模和修改后,是时候进入FumeFX插件。 所以首先我们将创建FumeFX对象源,我们将添加我们的对象。 要创建FumeFX对象源,请转到创建面板>帮助程序> FumeFX>对象Src。 单击此按钮并将其拖动到视口中。 现在转到“修改”面板,对参数进行一些更改。 将对象类型更改为实体。 将Smoke设置为25.0,然后转到Velocity部分,将Object设置为5.0和Extra为15.0。 保持其他参数不变。

Step 04: Create a FumeFX Container

We are going to use FumeFX as it's very simple to use, but still has many options and parameters. We'll cover as much as is required for this particular tutorial.

So let's start with the FumeFX Container. Go to the Create panel and select Geometry > FumeFX > FumeFX. Click on the FumeFX button and drag it into the viewport, then go to the Modify panel and set the Size and Spacing as follows. Width: 400, Length: 400, Height: 600 and Spacing: 1.2.

Now set the Position of FumeFX to the following: X: 00, Y: 00, Z: 00.

步骤04:创建FumeFX容器

我们将使用FumeFX,因为它使用很简单,但仍然有很多选项和参数。 我们将覆盖这个特定教程所需的。

所以让我们从FumeFX容器开始。 转到创建面板,选择几何> FumeFX> FumeFX。 单击FumeFX按钮并将其拖动到视口中,然后转到“修改”面板,并按如下所示设置大小和间距。 宽度:400,长度:400,高度:600和间距:1.2。

现在将FumeFX的位置设置为以下:X:00,Y:00,Z:00。

Step 05: Create a Wind Force

To push the fire and smoke in a certain direction, we'll use Wind. To create this, go to the Create panel and select Space Warps > Forces > Wind. Click on it and drag it into the viewport, then change the Strength to 2.0.

Now set the Position of FumeFX to X: 250, Y: 00, Z: 150. Set the Rotation X: 0.0, Y: -90, Z: 0.0.

步骤05:创建风力

为了推动火和烟在一定方向,我们将使用风。 要创建它,请转到创建面板,选择空间扭曲>力>风。 单击它并将其拖动到视口中,然后将“强度”更改为2.0。

现在将FumeFX的位置设置为X:250,Y:00,Z:150.设置旋转X:0.0,Y:-90,Z:0.0。

Step 06: Modify the FumeFX Container

After setting up the FumeFX Container, it's time to modify the parameters. So select the Container and go to the Modify panel. Now click on the 'Open FumeFX' UI button and a new window will appear. As you can see, there are six sections in this FumeFX interface and we will modify them one by one. So let's start with the Obj/Src section. In this section you just have to add the FumeFX Object Source which we generated earlier. So go to the Obj/Src section and click on the Pick Object button, then select the FumeFX Object Source and Wind Force.

步骤06:修改FumeFX容器

设置FumeFX容器后,即可修改参数。 因此,选择容器并转到“修改”面板。 现在点击“打开FumeFX”UI按钮,将出现一个新窗口。 如你所见,在这个FumeFX接口中有六个部分,我们将逐一修改它们。 所以让我们从Obj / Src部分开始。 在这一节中,你只需要添加我们之前生成的FumeFX对象源。 因此,转到Obj / Src部分,单击选择对象按钮,然后选择FumeFX对象源和风力。

Step 07: FumeFX - General Parameters

After finishing the setup of the Obj/Src section, let's set up the General Parameters section. We have already the set General Parameters to Spacing: 1.2, Width: 400, Length: 400 and Height: 600. Now we'll move ahead to the Output Range, set the Start Frame: 0, End Frame: 200, then go to Paths, where we set the FXD Files (Cache Files) path. So click on the button which is next to the Default Path and set the path as per your Folder Structure. Now move ahead to the Playback Range and set the Play From as 0 and Play To as 200. So these are some simple modifications in the General Section.

步骤07:FumeFX-一般参数

完成Obj / Src部分的设置后,让我们设置常规参数部分。 我们已经设置了间距的常规参数:1.2,宽度:400,长度:400和高度:600。现在我们继续前进到输出范围,设置开始帧:0,结束帧:200,然后转到 路径,我们在其中设置FXD文件(缓存文件)路径。 因此,单击默认路径旁边的按钮,并根据您的文件夹结构设置路径。 现在向前移动到播放范围,并将播放从0和播放到200.因此这些是在一般部分的一些简单的修改。

Step 08: FumeFX - Simulation Parameters

After finishing the setup of General Parameters, let's modify the Simulation Parameters. Go to the Simulation tab and apply the following settings. Change the Vorticity to 1.0 and the X Turbulence to 0.5. Now go to Turbulence Noise and set the Scale to 2.0, Frames to 1.0, and Details to 5.0.

Now go to Fuel and increase the Expansion to 2.0, keeping the other parameters as they are. Then go to Smoke and set the 'Dissipation Min. Dens.' to 5.0 and Dissipation Strength to 5.0 to dissipate the smoke fast. Keep the other parameters as they are and hit the Simulation button. It will take around 3-4 hours to finish.

步骤08:FumeFX-模拟参数

完成一般参数设置后,让我们修改模拟参数。 转到模拟选项卡并应用以下设置。 将涡度变为1.0,X湍流变为0.5。 现在去湍流噪声和设置缩放2.0,帧到1.0,细节到5.0。

现在去Fuel并将Expansion增加到2.0,保持其他参数不变。 然后去Smoke并设置'Dissipation Min。 Dens。 到5.0和耗散强度到5.0,以快速消散烟雾。 保持其他参数,并按下模拟按钮。 这将需要约3-4小时完成。

Step 09: FumeFX - Rendering Parameters

After finishing the simulation, just make sure that everything is as per your requirements. Now it's time to set the colors of the fire and smoke. So go to Rendering section and select the Fire tab. Right-click on Color and change it to Key Mode, then change the Gradient Color as shown in the image. Now move on to the Smoke Parameters. Set the smoke color to gray and reduce the Opacity to 0.5, then turn on the Cast Shadows and Receive Shadows options (so when we add the light, we should see the smoke's shadow).

步骤09:FumeFX - 渲染参数

完成模拟后,只要确保一切都符合您的要求。 现在是时候设置火和烟的颜色。 因此,转到渲染部分,选择Fire选项卡。 右键单击颜色并将其更改为键盘模式,然后更改渐变颜色,如图所示。 现在转到烟雾参数。 将烟的颜色设置为灰色,并将不透明度降低到0.5,然后打开投射阴影和接收阴影选项(因此,当我们添加光时,我们应该看到烟的阴影)。

Step 10: FumeFX - Illumination Parameters

After finishing the Color settings, it's time to add light to the scene. We'll create two lights: one Target Spot and one Omni Light. To do that, go to the Create panel and select Lights > Standard > Target Spot. Click on the Target Spot light and create it in viewport. Now set the light position to X: -1850, Y: -1035, Z: 1950, and its Target Position to X: 20.0, Y: -15.0, Z: 200.0. Create the Omni Light with same procedure and change its Position to X: 825, Y: -600, Z: 550.

Now select the lights and go to Modify panel, then turn on the Shadow and set it to Ray Traced Shadows. Now go to Shadow Parameters and turn on Atmosphere Shadows. After finishing these settings, return to FumeFX Container. Go to the Illumination section and add these lights into the Light section by clicking the Pick Light button. Now turn on Multiple Scattering, set its Max Depth to 8 and Falloff to 8.0, and leave the other parameters as they are.

步骤10:FumeFX-照明参数

完成颜色设置后,是时候给场景添加光。 我们将创建两个灯:一个目标点和一个全向灯。 为此,请转到创建面板,然后选择灯光>标准>目标点。 单击目标点亮并在视口中创建它。 现在将光位置设置为X:-1850,Y:-1035,Z:1950,其目标位置设置为X:20.0,Y:-15.0,Z:200.0。 使用相同的步骤创建Omni Light,并将其位置更改为X:825,Y:-600,Z:550。

现在选择灯光并转到“修改”面板,然后打开阴影并将其设置为“光线跟踪阴影”。 现在转到阴影参数,打开大气阴影。 完成这些设置后,返回FumeFX Container。 转到照明部分,并通过单击选择灯按钮将这些灯添加到灯部分。 现在打开多重散射,将其最大深度设置为8,将衰减设置为8.0,并保留其他参数。

Step 11: Rendering

After finishing the light setup, it's time for rendering. Go to Render Setup by pressing F10 and set your desired Output Range, Output Resolution and Output Path. Go to the Render Elements tab and click on the Add button, bringing up a new window. Select the FumeFX Fire and FumeFX Smoke elements and click OK. Now just hit the Render button. It will take around 4-5 hours to finish rendering.

步骤11:渲染

完成灯光设置后,它的时间来渲染。 按F10进入渲染设置,设置所需的输出范围,输出分辨率和输出路径。 转到渲染元素选项卡,单击添加按钮,打开一个新窗口。 选择FumeFX Fire和FumeFX Smoke元素,然后单击确定。 现在只需点击渲染按钮。 完成渲染需要4-5个小时。

Step 12: Post-production

After finishing the rendering, import both the fire and smoke renders into After Effects, or any other compositing software which is convenient for you. I'm using After Effects, so import both elements and drag them into the timeline. Select the fire element, then right-click and change its Blending Mode to Add. You can include Glow effects and make some changes in the Parameters. Select the smoke element and make whatever changes you like to the color or brightness settings. Now render the final output and you'll get your finished thick smoke!

步骤12:后期制作

完成渲染后,将Fire和Smoke渲染导入After Effects或任何其他对您方便的合成软件。 我使用After Effects,所以导入两个元素,并将它们拖动到时间轴。 选择fire元素,然后右键单击并将其混合模式更改为添加。 您可以包括辉光效果,并在参数中进行一些更改。 选择烟雾元素,并对颜色或亮度设置进行任何您喜欢的更改。 现在渲染最终的输出,你会得到你的完成浓烟!
