How to Create Bubbles in KeyShot 8 Using the New Geometry Node

by | Nov 1, 2018 | 0 comments

 KeyShot 8 brings us a lot of exciting new features. One of these features is the new geometry node/shader capability. Geometry nodes directly transform your geometry in a non-destructive manner. Geometry nodes are able to add to, subtract from, or reshape the geometry and are often driven by textures. This allows you to create 3D textures on surfaces or control the entire shape of the geometry. 

 What is the Bubbles Geometry Node in KeyShot 8?

One of KeyShot 8’s geometry nodes is called Bubbles. In KeyShot, bubbles are sphere-shaped cavities of air trapped within a solid. Use the Bubbles node when you want to add random variation and distribution of air bubbles inside the material of your object. Make sure the material is transparent to some degree, otherwise the bubbles will not be visible. To make the bubbles appear in your geometry, connect the Bubbles node to the Geometry socket of the root Material node.

 Use Cases for the Bubbles Geometry Node

So, when would you want to add bubbles to a material inside KeyShot? Over the years, KeyShot has helped designers, engineers, and others share ideas through its rendering and animation capabilities.

KeyShot is all about simulating light and materials accurately. Sometimes, we need to render materials that contain small imperfections or cavities. Modeling these imperfections or air cavities is prohibitively tedious and time-consuming.

However, the Bubbles geometry node makes adding such such qualities to a solid quick and easy. Examples of when you might add bubbles to a material include:

  • Carbonated beverages
  • Gels
  • Resins
  • Foams
  • Turbulent water
  • Decorative glass

 How to Make Bubbles in KeyShot 8

By using a single geometry node in KeyShot, you can push and pull a few sliders to add any variety of bubbles to any solid.

 Here’s the step-by-step on how to do it:

  1. Assign a Solid Glass material to the volume you wish to add bubbles to (so you can see the bubbles inside).

  2. Double-click the Solid Glass material to edit its Material Properties.

  3. Click the Material Graph button to enter the Material Graph.

  4. Right-click in the Material Graph workspace and hover over Geometry and select Bubbles.

  5. Connect the Bubbles node to the Geometry socket of the Base Material node. Do this by clicking and dragging the white dot on the right side of the geometry node to the white dot labeled Geometry on the left side of the root node (denoted with thicker outline).

  6. Double-click the Bubbles node to open its properties. Click Execute Geometry Nodes.

  7. Bubbles will vary based on the size of the model and scene units. Adjust the bubbles settings as needed and click Execute Geometry Nodes button as needed to re-calculate the bubbles.

The next time you need to add bubbles to a model, follow the steps above and you’ll have bubbles in no time! For more detailed information, consult the KeyShot 8 online manual. For a visual demonstration, please view the Bubbles Quick Tip below.
