Bug Extremely bright RT reflections in 7.5.3

1. New HDRP 7.5.3 project with 2019.4.20f1.
2. Fix All for DXR.
3. SampleScene.unity
4. Creat a Sphere, assign a material with Metallic 1 and Smoothness 1.
5. Disalbe all Reflection Probes.
6. New Global Volume.
7. New Profile.
8. Add Override > Lighting > Screen Space Reflection > enable RT.
[Result]
The sphere is extremely bright.

9. Open the project in 2020.2.5f1 and update to HDRP 10.3.1.
[Result]
Good.

Thanks.

 

It's probably some exposure issue (we've had those on RT reflections many times in past).

But do you really need RT on 2019.4? I mean RT even on newest HDRPs is still experimental and it's definitely not great on the first version (2019.4). Unity hasn't worked on the raytracing updates for that version for a long time now.

If you really want to use raytracing, I'd recommend bleeding edge Unity version as that's where the RT improvements land.

 

With newer Unity, I simply lose Enlighten realtime GI, which has decent effect and cost.

 

Enlighten support has been added back but it's not yet in versions we get through Unity Hub: https://github.com/Unity-Technologies/Graphics/pull/3385

But this does mean it will be available in future 2021.2 alphas / betas.
