Blender 3D Incredible Models

By: Arijan Belec

Overview of this book

Blender is a massively popular and powerful 3D program, with versatile modeling abilities that make it a great way to enter the 3D modelling world. Blender 3D Incredible Models is an extensive guide for those new to hard-surface modeling with Blender, helping you understand the complete range of tools and features it offers and how to employ those efficiently to create realistic models. You’ll be led through progressively more challenging modeling projects— from an assault rifle and an army tank to a sci-fi spaceship model—giving you a glimpse of all the skills you’d need in Blender’s vast ecosystem of features and functionality, ranging from textures, rendering, and UV mapping to lighting, rigging, and beyond. Each engaging project builds upon the last until you’re equipped with everything you need to tackle your own modeling challenges, whatever they may be. By the end of this Blender book, you won’t just know how to create the models covered here, but you’ll be able to turn your own concepts and references into 3D Blender models too!

Rigging the wheels and sprockets

We will now map the rotation of the sphere to the rotation of the wheels. This will make the wheels rotate in relation to the empty sphere. In the following steps, we will add constraints to all the wheels and sprockets:

  1. Add a Transformation constraint to the sprocket, and map from Rotation to Rotation. Set X Max to in the Map From menu, and to 100° in the Map To menu.

Remember to set the same settings as before at the top of the constraint menu:

Figure 11.17 – Sprocket constraint

For every one degree that the empty sphere rotates, the sprocket will now rotate 100 degrees. The problem now is that the sprocket is not turning quickly enough in relation to the tracks, which causes the tracks to clip through the sprocket as they are rotating:

  1. Tweak the X Max value in the Map To menu until you find a value that works well.
