Alina Ledeneva shared a deep dive about why a gameplay camera and SceneCaptureComponent2D can produce different framing, explaining the workflows in UE5 and giving two solutions.

80lv's platform is a resource for game developers and 3D artists, offering insights into game development techniques, industry trends, and visual effects (VFX). Through articles, interviews, and case studies, 80lv offers insights into 3D modeling, texturing, animation, and rendering. Developers and artists can learn about game engines, shader programming, and advanced rendering techniques to create immersive and visually stunning games and animations.

SceneCaptureComponent2D and gameplay cameras in UE5 can produce mismatched framing when aspect ratios change because they use different projection rules. The gameplay camera defaults to Maintain Y Axis (preserving vertical FOV), while SceneCapture effectively uses Maintain X Axis (preserving horizontal FOV). This article explains the projection pipeline for both systems, breaks down the frustum math behind FOV recalculation, and provides two solutions: a Blueprint approach that recalculates FOV values, and a C++ implementation using CustomProjectionMatrix to create a custom SceneCaptureComponent2D that supports all Maintain Axis modes.
