--3ds Max-- Bubbles

Very simple way to create them without having hundreds of small animated spheres in your scene

1. First, create a sphere in the center of the scene with the following parameters:

X, Y, Z: 0, 0, 0
Radius: 100
Segments: 64 Now, add a spotlight to the scene with the following world
X, Y, Z: 400, - 200, 400

Spot Target:
X, Y, Z: 0, 0, 0

Then, set its color to pure white.

2. Now, open the Material Editor. Activate the SLOT #1. Lock Ambient and Diffuse together and set the color to pure white. Set the shading to metal, and change the following parameters:
Shininess: 70
Shininess Strength: 30

Self-Illumination: 0
Opacity: 50

3. Now, apply the material to the sphere. Render in the front view with the Force 2-Sided option set ON. Save the rendering.
Start Photoshop, Photostyler, or anything else to crop the picture to make it square. Save it. Here is what you should have:

4. Now, it's time to create the particle system. all the values used in this
tutorial for the spray are subjective. You must adjust these values to fit your scene requirements.
Create a spray using the parameters as in this picture:

5. Now, open the Material Editor. Set the Shading to Phong, Filter to light grey (R: 180, G: 180, B:180) and use the following values:
Shininess: 0
Shininess Strength: 0
Self-Illumination: 100
Opacity: 100

6. Then, go to the Maps section. Load the bubble map you croped and saved as a Diffuse Map. Then, duplicate it to the Opacity Map. Go back to the Diffuse Map settings. Under Output, change the RGB Level to 2 (optional).
Your map is ready !

7. Select the spray and assign the map you've just created to it. Render with the Force 2-Sided option set ON.
