Unreal Engine Physics Essentials

By: Devin Sherry, Vladimir Alyamkin, Katax Emperore

Overview of this book

This book gives readers practical insight into the mathematical and physics principles necessary to properly implement physics within Unreal Engine 4. Discover how to manipulate physics within Unreal Engine 4 by learning basic real-world mathematical and physics concepts that assist in the implementation of physics-based objects in your game world. Then, you'll be introduced to PhAT (Physics Asset Tool) within Unreal Engine 4 to learn more about developing game physics objects for your game world. Next, dive into Unreal Engine 4’s collision generation, physical materials, blueprints, constraints, and more to get hands-on experience with the tools provided by Epic to create real-world physics in Unreal Engine 4. Lastly, you will create a working Vehicle Blueprint that uses all the concepts covered in this book, as well as covering advanced physics-based topics.

Changing units of measurement in 3ds Max and Maya


For both character and environmental artists, it is very important to know how to change the units of measurement in the third-party 3D modeling so that when assets are exported from the art program and then imported to Unreal Engine 4, the scale is correct and as intended by the artist. Keeping in mind that Unreal Engine 4 uses the measurement conversion of 1 uu equaling 1 cm by default, we want to make sure that the units of measurement in our 3D art program uses the same conversion.

To change the units of measurement in 3ds Max (2013 version), select the Customize option and then Units Setup. Here, click on the System Unit Setup button and change the units of measurement as follows:

In Maya, we can change the units of measurement by clicking on Window from the toolbar. Now, select Settings/Preferences from the drop-down window and then Preferences. In the Preferences dialogue box, select Settings. Under Working Units, we can change the linear units to centimeter.
