Exposure Is More Extreme In High-End Mobile Preview Modes

Exposure Is More Extreme In High-End Mobile Preview Modes

Questions & Answers
Description

In high-end mobile preview modes the exposure will return much more exaggerated results. This is related to the new default tone mapper settings since changing r.TonemapperFilm to 0 solves the issue.

Steps to Reproduce
  1. Open a blank project
  2. Change the exposure to "fixed at log +1 = Brightness 2x"
  3. Change the preview rending level to iOS Metal Preview

RESULT
The scene gets noticeably brighter

EXPECTED
The exposure remains somewhat consistent between rendering previews.
