ABSTRACT BACKGROUND

In this tutorial we’re going to create an abstract background image in 3ds Max. It seems that bokeh backgrounds have been extremely popular during the last few years so we’re going to create one as well. There are many Photoshop tutorials available, but here I’m going to show you how to create bokeh background in 3ds Max. I think 3ds Max is perfect for creating abstract backgrounds because of it’s parametric nature. It’s really easy to change everything with parameters. I’m using 3ds Max 2011, but many older versions should work as well.

Step 1 Scanline Renderer

We’re going to render the bokeh effect with Scanline Renderer. If you are using mental ray renderer you have to change that ( Rendering > Render Setup… > Common tab > Assign Renderer > Production > Default Scanline Renderer ).

Step 2 Particle Cloud

Our abstract background will consist of two elements: particles and background. First, we’ll create the particles. I’m using Particle Cloud, but feel free to use Particle Flow if you want to. I think it’s just a little easier / faster to use Particle Cloud for our purpose here, because we don’t need any of those advanced features that Particle Flow has to offer. So let’s create a particle cloud in the front viewport ( Create panel > Geometry > Particle Systems > PCloud ). Select the particle cloud, go to the modify panel and apply the following settings:

• Basic Parameters
  • Display Icon
    • Rad/len: 670
    • Width: 1200
    • Height: 900
  • Viewport Display
    • Mesh
• Particle Generation
  • Particle Quantity
    • Use total: 500
  • Particle Timing ( We create all particles between frames -29 and 0 so that they are visible already at frame 0 )
    • Emit Start: -29
    • Emit Stop: 0
    • Display Until: 0
    • Life: 30
    • Variation: 0
  • Particle Size
    • Particle Size: 20
    • Variation: 100
    • Grow for: 0
    • Fade for: 0
  • Uniqueness
    • Seed: 704 ( Feel free to try different numbers here )
• Particle Type
  • Standard Particles: Facing ( flat four sided polygons that will always face the camera )

Create a target camera ( Create panel > Cameras > Target ) in the top viewport. Right-click on the Perspective view and press ‘c’ in the keyboard to change it to a camera view. Position the camera target in to the middle of the particle cloud and the camera itself like in picture below.

Render your scene to make sure you get something like the picture below. I rendered with 700 x 438 px dimensions.

Step 3 The Particle Material

Next we’re going to create the material for the particles. This is the most complicated part of this tutorial, but don’t worry, nothing really hard here. Open Material Editor ( Press ‘m’ in keyboard ) and create the material for the particles:

1. Select the Particle Cluod and assign the first standard material to it
2. Face Map: YES ( map in material will be automatically applied to each face of the object )
3. Diffuse: Light gray ( RGB 230, 230, 230) ( diffuse and ambient are locked by default so both will have this color )
4. Opacity: 0
5. Advanced Transparency: Type: Additive

Apply an opacity map:

1. Opacity Amount: 40 ( particle transparency )
2. Opacity Map: Gradient Ramp ( Material/Map Browser > Maps > Standard > Gradient Ramp )
3. Gradient Ramp Flags:Flag #1: Color: RGB 44, 44, 44 Position: 0Flag #2: Color: RGB 44, 44, 44 Position: 88Flag #3: Color: RGB 64, 64, 64 Position: 92
   Flag #4: Color: RGB 64, 64, 64 Position: 96
   Flag #5: Color: RGB 0, 0, 0 Position: 100
   ( Click on the color gradient to add a new flag. Right-click on a flag to modify or delete it. )
4. Gradient Type: Radial

Let’s utilize Particle Age map to add some variation to the opacity of individual particles:

1. In the Maps rollout, click on the ‘Gradient Ramp’ Map
2. Click on the ‘Gradient Ramp’ again. ( Material/Map browser appears )
3. Double-click on the ‘Particle Age’ map ( Maps > Standard > Particle Age )
4. Select ‘Keep old map as sub-map?’ and click ‘OK’. ( Now we have Particle Age as opacity map and Gradient Ramp as a sub-map of Particle Age )
5. Drag and drop the Gradient Ramp map from ‘Color #1 Map’ slot to ,Color #2 Map’ slot. Select ‘Copy’ when asked.
6. Drag and drop the Gradient Ramp map from ‘Color #1 Map’ slot to ,Color #3 Map’ slot. Select ‘Copy’ when asked.
7. Adjust the Gradient Ramp Flags in Color #2 slot:Flag #1: Color: RGB 66, 66, 66 Position: 0Flag #2: Color: RGB 66, 66, 66 Position: 88Flag #3: Color: RGB 96, 96, 96 Position: 92
   Flag #4: Color: RGB 96, 96, 96 Position: 96
   Flag #5: Color: RGB 0, 0, 0 Position: 100
   ( Click on the color gradient to add a new flag. Right-click on a flag to modify or delete it. )
8. Adjust the Gradient Ramp Flags in Color #3 slot:Flag #1: Color: RGB 99, 99, 99 Position: 0Flag #2: Color: RGB 99, 99, 99 Position: 88Flag #3: Color: RGB 144, 144, 144 Position: 92
   Flag #4: Color: RGB 144, 144, 144 Position: 96
   Flag #5: Color: RGB 0, 0, 0 Position: 100
   ( Click on the color gradient to add a new flag. Right-click on a flag to modify or delete it. )

Now infant particles are darker / more transparent than particles that have some age. The effect of the Particle age map is not drastic but in my opinion necessary to get some variation to the opacity and brightness of individual particles. Render your scene to make sure it looks similar to picture below.

Our abstract bokeh background doesn’t look like much yet.

Step 4 Abstract Background Material

The next step is to create the environment (background) map for our image. Open Material Editor ( Press ‘m’ in keyboard ) and create the environment map:

1. Select the second material slot
2. Click on ‘Get Material’ button and select Composite map from the Map list ( Material/Map Browser > Maps > Standard > Composite ). Make sure you select Composite map and not Composite material!
3. Click ‘Add a new layer’ to add a second layer to the composite map
4. Add Gradient Ramp map to the first layer of the Composite Map:Coordinates rolloutEnviron: SelectedMapping: Screen
   Angle: W: 90
   Gradient Ramp Parameters rollout
   Flag #1 Color: RGB 139, 84, 5 Position: 0
   Flag #2 Color: RGB 255, 229, 192 Position: 100
5. Add Noise map to the second layer of the Composite Map:Noise Parameters rollout Noise Type: FractalLevels: 10
   Size: 20
   Color #1: RGB 100, 100, 100
   Color #2: RGB 255, 255, 255
6. In the Composite Map, change the blending mode of the ‘Layer 2’ to ‘Color Burn’

Let’s apply the map to the environment:

1. Open environment settings ( Rendering > Environment… )
2. Drag and drop the environment map from the material editor slot to the Environment Map slot. Select ‘Instance’ when asked and click ‘OK’.

Render your scene to see how your abstract background looks.

As you see the environment background brings a lot of life and color to the image. Feel free to change the color in the background map.

Step 5 Depth of Field

As a last thing, we’re going to make the image more interesting by adding real depth of field effect to it. Select the camera and go to the Modify Panel to apply the depth of field effect:

• Parameters rollout
  • Multi-Pass Effect
    • Enable: YES ( Make sure ‘Depth of Field’ is selected in the drop down list )
• Depth of Field Parameters
  • Focal Depth
    • Use Target Distance: YES ( particles near the camera target will appear sharp )
  • Sampling
    • Display Passes: YES
    • Use Original Location: YES
    • Total Passes: 100 ( try lower values if it takes a long time to render )
    • Sample Radius: 30
    • Sample Bias: 0,5

Render your image to see the difference.

Finally, do some color correction in Photoshop if you like:

• Brightness: 40
