Introduction
In Fig. An example of a flame generated by the module Aura.
I greet you in this lesson. Here you can learn how to build a fire in the environment of three-dimensional modeling program 3 d studio max. As you might imagine, in a medium 3 d studio max there are many ways to create a living flame, we offer you a way to create a fire through a special module - Aura of Chaos Group. As you know, embedded software can simplify the creation of something, but you need two things: First - a program (module), the second - the ability to work with this program.
On the example of a burning candle we will tell you how to get the flame alive with the help of this module. But that's not all, of what can be achieved by this module. Along with the fire at once, and you can create a smoke effect. And if further explore all the features, it will also create and explosion effects, and almost everything that relates to a flame.
The module is built in 3 d studio max as an atmospheric effect, and creates a fire, using an object as the source of the flame (at least, is one way to generate the flames).
Preparing the scene
In order to avoid creating a fire hanging in the air, I made a candle with a candle. You too can make it, there's no big deal. The candle is made from a cylinder, just need the top at one end of a little push, then rounded, and the candlestick made of the circuit using the modifier Lathe, wick - the usual Line, only visualized.
In Fig. A model of a candle, prepared for the job.
Pay attention to the fact that, where a candle wick, I placed an additional sphere, this sphere and will be the source of the flames that will be used by the module.
In Fig. 2 Preparation of the object to render the flames.
In the first picture of this sphere does not, because once we give it as a source, we will hide it. When rendering the flames will be used, and when rendering - no.
Starting the AURA
We basically have everything you need to connect the module itself. Let us turn to the tab Rendering - Environment, a window Environment and effects, there in the Atmosphere tab, click the add button and select the Aura for 3 D Studio Max as shown
In Fig. Adding an Aura to the scene.
Once you add the effect of a window control module AURA.
Create and configure a flame
In order to create a fire, we need to dig to the settings for the benefit of all that hard to do everything right in order of need to go through all the tabs from the one in which we now are - tab Objects.
In Fig. Select a viewport.
The first step is to add an object (in our case it was the same area), click on the button Select from Viewport, marked in the figure above, and then either simply click on the field, or press the H button and select an object by name from the list. After that, the name is written in the upper window pane Aura, as shown.
In Fig. 2 Select the object.
Now we must add that as a type of fire will be created on our site.
In Fig. 3 Select the type of flame.
Below the bottom window is a button Add initializer, marked in the figure above. Click on it, then come out the same window that will ask for the support of the object type - the figure below
In Fig. 4 Select the standard method based on the object geometry.
Please select, Default Object Initializer. Here we have chosen a standard way based on the geometry of the object, the other way associated with the texture. So, if everything is correct window should look something like this:
In Fig. 5 window, after the necessary adjustments.
As you've probably noticed, the following were some of our initialization settings such as a flame, such as in the picture:
In Fig. 6 Setting the initialization of the flame.
This is the default setting of the flame, we still need to change a setting to change the Source Type Non - solid at the Solid - injector. As the figure below.
In Fig. 7 Configuring needed to create the flame throughout the volume of hidden areas.
Thus, we have the fire will be created throughout the volume of hidden areas, not just on the border.
Init tab duplicates the configuration initialization pure fire, because it jumped, let's go to the tab Grid.
In Fig. 8 parameters changing perceptions of the flame.
Here we do nothing will change. Parameter Desired number of cells be dependent size and number of flames. It depends also render the term of the flame.
The tongue of flame have finite size, ie restrictions as to the upper and the lower side. Thus, changing this setting you can achieve different perception of the flame. The higher the number, the more flames and the smaller their size, as issuance of the flame is based on a geometric object - we have a sphere.
The next tab Solver - we have not needed it is possible to calculate the flame itself, but first go to the tab Cache, it is because when calculating Aura adds to the media files to render, in the Cache tab must specify the place.
In Fig. 9 The parameters for selecting files miscalculation.
Here, click the button Select project, we propose to select the folder, I suggest you create some kind of special for this folder, there will be a lot of files, then click the button Use path.
In Fig. 10 Selecting the folder for the miscalculation.
Select project in front of the button will be the path to the folder where the files are now stored on the mistakes, I have this folder K: \ kursovik \ 1
So, now we can go to the tab and start Solver by flames.
In this tab there are options that control the creation and rendering of particles, which will render the fire.
The upper part is called Simulate, here you are running mistakes to create a flame.
In Fig. 11 Parameters rendering animation.
buttons trigger errors, and data in the windows show a frame in which to start and where to complete miscalculation miscalculation.
All other settings at the moment we are not going to touch these settings, we need now only include the rendering of fire, Flames in the segment must also be checked next to Enable Flames.
In Fig. 12 Setting up the dynamics of the flame.
In addition, in the window are the parameters of the flame, which would have obtained after the calculation for our example, these settings are quite suitable.
Also, you may have noticed lower segment of the Smoke of a similar place for a tick next to Enable Smoke, this segment is responsible for enabling calculation of the parameters of smoke and fumes. While we will not include it.
If you now click on one of the three buttons in the upper segment, then start rendering the particles, which render the flames. Perspective view will look something like Figure 13, if you have a polygonal map, or as in the figure below 14, if you choose to display only a mesh of polygons.
In Fig. 13 Step rendering particles (polygonal map).
In Fig. 14 Step render the particles (the grid).
therefore, the red triangles - the particles that formed the flames, and if you try to count the picture now - you will not get anything now, the flame will not be visible. We return to the Control Panel module AURA.
Calculating the flame
Let us turn to the tab Render.
In Fig. A tab Render.
to display the particles are obtained when calculating the flame - it is necessary to add how it will look like the very flame. To do this, click Add Shader, a window appears, choose where Flame Shader: Color curve.
In Fig. 2 Select the visualization of the color curve.
thus, the fire will be rendered according to our particles, based on the color curve.
The panel has changed. There are additional segments, where you can customize the display of fire.
In Fig. General view of the three settings.
Calculate the picture now. At this stage, the resulting image is like a flame will appear, but it still will be black and white.
In Fig. 4 The first rendering of the flame.
In order to color the flame was right, it is necessary to change the curve color.
Pay attention to the segment of the Flame Shader: Color parameters. On the grid shows the direct and oblique gradient strip under it.This segment is responsible for setting and changing the color of the flame.
In Fig. 5 Curve of color.
In order to fire was more or less similar to the present, it is necessary to change the curve. Changes to the curve control points. To add a point on the curve - you need to click on the curve of the left mouse button while holding down CTRL. There is one small caveat: in order to cancel the effect of the curves in the window - it is necessary to right click on the window and select UNDO, And you can load / save the resulting curves.
In Fig. 6 Options pop-up window.
We have here a flame, changing curves.
In Fig. 7 The result of setting the color curve.
In order to get a flame, you can arrange for drawing their curves as we have.
In Fig. 8 Variations of color curves.
If you play a little crooked, you can get different combinations.
In Fig. 9 show examples of flame-colored vinyl for debugging.
There is also a very useful parameter, which is changing, we change the brightness of the color of the flame. Located in the segment parameter Flame Shader: General parameters, it is called Brightness. We have put this option to a value of 2.5. This is no accident.
In Fig. 10 changes in brightness setting.
Figures - Brightness value on the left is 1, the right - is 2.5
In Fig. 11 settings of brightness.
All other parameters remained unchanged.
Creating a smoke
Now you have a candle flame, but to add a little realism, add another and the effect of smoke. To create it do not need anything extra, the module is already built Aura creating smoke, you just turn it on.
Locate the module in the Control Panel tab Aura solver, it has a segment of smoke
In Fig. Adding a smoke.
in this segment need to tick the box marked Enable smoke, other options are not fashionable touch.
Now we need to re-run the simulation of fire, and together with the red particles, fire managers will appear black, are responsible for the smoke. Or, if you have enabled the mapping of polygons - particles of light will be red, and smoke particles - white.
In Fig. 2 Display the rendering phase of the smoke.
Now that the smoke when rendering should display the same as in the case of the fire by adding that, as it will appear. To do this in the Control Panel module Aura Render tab in the Default Render the segment to press the button and select the Add Shader Smoke Shader.
In Fig. 3 Setting the smoke to display when rendering.
Nothing more needs to be done, if it is to count the picture, you can see the smoke over the fire, the color of smoke is also given by the curves, as well as the color of the flame in a separate window curves. If you calculate the image with different color of the environment - the smoke will be noticeable in many ways.
In Fig. Outcome 4.
