It’s All About Primitives
This Mozilla and Goo Christmas challenge was a large competition based around the use of simple shapes to build the worlds. To create a primitive, click on the Create menu at the top of the screen. The following 3d primitives are available:
All the primitives you need!
Click on the sphere icon to create one in the viewport. A sphere is a perfect start for our Santa Claus, we will use it to build his chest. With the sphere selected, in the left panel, click on the Geometry category, to view the Shape Options:
Use the sliders to increase or decrease the amount of samples in your sphere in both the X and Y direction. The more samples, the smoother the surface.
Should Santa Be Red or Green?
Below the Shape Options, if you click on the Materials category, you can see that Goo Create already created an empty material for you. In the Materials, color (diffuse) section, click on the colored square. A color picker will appear and you’ll be able to change the color of your entity.
Under the color slot you might have noticed a Drop Texture placeholder. If you want to add any texture to your entity just drag and drop an image file from your desktop or from your project library.
Limb by Limb
Once you’ve created your first primitive, practice some more by going through the following construction map using the other primitive shapes available:
All these limbs can be tiresome to manipulate, and that’s when grouping becomes very handy. You can create an empty entity object by clicking on the following icon in the Create panel. It’s a bit further down from the primitives!
In the project library, drag and drop all the primitives you created on the new entity. You’ll then get a complete Santa that can be moved around.
This jetpack needs some smoke!
Fire and smoke are actions handled through one of Create’s secret weapons: the state machine. Click on one entity that should be our smoke emitter (in this case a cylinder located at the bottom of Santa’s jetpack). Next, click the Add Component button at the top left of the screen. It is located to the right of the entity’s name. In the Add Component drop down menu, choose State Machine. Click the State Machine panel to see its options. In the default state (called simply State), click Add Action, then choose Smoke FX in the library.
Now simply press the play button at the bottom of the screen to see smoke coming out of your jetpack.
So.. Where Is the Snow?
If you select the root ‘Scene’ in the hierarchy on the right panel, Post Effects and Environment should appear inside the left panel. Expand the Environment panel, and you will see the snow effect we’ve added for the occasion. You may need to place a check mark in the box next to ‘Snow’ to access the effects properties.
Velocity and rate are quite self-explanatory. Height refers to the distance from the camera’s current position.
Now add some snow to your scene to create that special holiday feeling!
