Challenge your understanding of packaging and deployment processes for Unreal-based projects targeting both mobile devices and PC platforms. This quiz covers platform-specific settings, common troubleshooting techniques, and optimization considerations essential for successful builds and smooth releases.
Which setting must be enabled to ensure that textures are compressed for mobile deployment, such as when preparing a project for Android or iOS?
Explanation: Texture Compression is essential for mobile deployment because it reduces the size of textures and optimizes them for the hardware on mobile devices. 'Texture Streamming' is a similar-sounding term but relates to how textures are loaded, not how they are compressed. 'Textura Compressian' is a misspelling and not a valid option. 'Texture Compiling' is not a recognized packaging setting for texture optimization.
When deploying a project for release on PC, which build configuration should you select to optimize for performance and exclude debugging tools?
Explanation: The Shipping build configuration is designed for released products, as it maximizes performance and omits debug tools. 'Development' and 'Debugging' include testing features and debugging code, which should not be present in final releases. 'Editor' is intended for use within the development environment and is not a deployment option.
A developer notices their PC build runs smoothly, but the same project crashes on mobile devices while loading shaders. What is the most likely cause of this problem?
Explanation: Mobile platforms often require different or simplified shader models compared to PCs, and using unsupported shaders can cause crashes during deployment. Low audio sample rate may degrade sound but won't typically crash the app. Having too many static meshes might lower performance, but shader compatibility is a more direct cause of failure. High-resolution mouse input is not relevant to mobile devices.
Which directory within your packaged project contains the application executable required to launch your PC game?
Explanation: The Binaries directory contains the executable files needed to launch the application on PC. 'Content' holds the project's assets, such as textures and meshes, but not executable files. 'Assets' is not a standard directory in this context. 'Plugins' contains optional extensions, not the main application files.
To effectively reduce the APK file size for an Android deployment, which option should be prioritized without reducing essential game quality?
Explanation: Removing unused assets is the most effective way to decrease the APK file size, as it ensures only necessary data is included. Increasing screen resolution or duplicating material instances can make the build larger and impact performance. Enabling verbose logging does not reduce file size and, if anything, may add to the data output.
