Unreal Engine Risk Assessment & Management 3

Question 1

What is the primary risk of relying heavily on Dynamic Shadows with a high shadow distance in a mobile Unreal Engine project?

Accepted Answer

High GPU cost can cause thermal throttling and frame drops on mobile devices

Answer

Dynamic shadows are computationally expensive, and excessive shadow draw distances significantly increase GPU workload, causing overheating and performance drops on mobile hardware.

Question 2

Which risk does an uncontrolled Derived Data Cache (DDC) size pose in a large Unreal Engine team environment?

Accepted Answer

A bloated shared DDC can exhaust network storage and slow down all team members' iteration times

Answer

A shared DDC that grows without bounds can consume network storage and degrade performance for the entire team when fetching or writing cached data.

Question 3

In a cinematic-quality Unreal Engine project using Sequencer, what is a key risk of not managing sub-sequence complexity?

Accepted Answer

Deeply nested or excessively large sequences can cause evaluation spikes and editor instability

Answer

Uncontrolled sub-sequence complexity leads to expensive evaluation passes each frame, causing hitches and potential editor crashes during playback or rendering.

Question 4

A team discovers that their Unreal Engine game crashes only on specific AMD GPU hardware. What is the most appropriate risk management response?

Accepted Answer

Isolate the crash using RHI validation layers and targeted hardware test rigs, then file a driver/engine bug

Answer

Using RHI validation to reproduce and isolate the crash on target hardware provides the data needed to properly diagnose whether the issue is a driver bug, engine bug, or shader error.

Question 5

What does 'scope creep' risk look like specifically in an Unreal Engine game development context?

Accepted Answer

Adding too many post-processing effects that were not in the original design document

Answer

Scope creep in UE development manifests as continuously adding features, visual effects, or systems beyond the original design, inflating budget and schedule risks.
