Scene Capture Cube renders distortion in standalone preview
I'm trying to implement a reflection floor using the Vehicle C++ example. The Scene Capture Cube is mirrored underneath the camera and parented to the car like so:
When playing the game in preview mode the reflection works fine
But when I try it out in the Standalone Game preview parts of the reflection are distorted
Did I miss something or is this a bug?
The selected answer is wrong. While true that Reflection captures have different distortion characteristics, that doesn't affect SceneCaptureCubes nor would it explain different behavior between the editor vs. standalone.
I spent an hour debugging this and it's a known separate bug: UE4 won't realloc rendertargets > your window resolution. So if your scenecapturecube texture size > your game window resolution, you'll see artifacts. This constraint doesn't happen in the editor.

Hey ultitech_David -
This is a known limitation to Box Reflection Actors. Both the Sphere and Box Reflection Actors have limitations in what they can and cannot do. In most cases you will want to use a Sphere Reflection Actor as they produce a better (less artifact and stretched) cubmaps. For the type of reflection that you are looking for I want to point you to our reflection documentation as straight flat reflections will always have certain limitations and quality loses, https://docs.unrealengine.com/latest/INT/Engine/Rendering/LightingAndShadows/ReflectionEnvironment/index.html
