[HDRP] Auto exposure effects occur on entering/exiting in play mode with Sprite Shape controller

Package: Scriptable Render Pipeline HD


Auto exposure effects occur on entering/exiting in play mode with "Sprite Shape controller".

Steps to repro:
1. Create a new HDRP Project.
2. Windows > Package Manager > 2D SpriteShape > Install.
3. Gameobject > 2D Object > Sprite Shape.
4. Enter in Play mode.

Actual Result:
Auto exposure effects occur on entering/exiting in play mode.

Expected Result:
Auto exposure effects should not occur.

Reproducible in:
2020.2.0a10, 2020.1.0b8, 2019.3.0f3 with Package Version 9.0.0, 8.1.0, 8.0.1, 7.1.8.

Occurring on Windows 10 & Mac 10.15

  1. Resolution Note:

    This is unfortunately expected. 

    The issue lies from the fact that we perform pre-exposure based on the exposure computed previous frame. For the first frame we don't have such exposure and we set an exposure texture that is "neutral" but cannot be correct for what is actually on screen, hence the exposure system will adapt starting from that neutral value. 

    A content specific workaround for an application that I can suggest to the user is: if you are able to identify what the a fixed exposure could be on the first frame, start the application with fixed exposure with the value that is correct for your starting point (this is specific to your application). After the first frame you can switch back to automatic mode and the automatic exposure system will work with a good starting point.
