[Virtual Texturing][HDRP] VT cache settings cannot be edited in HDRP asset



1a. Open new 3D template
1b. Add HDRP in package manager (10.0.0-preview.27)
1c. select Fix All and Create One on HDRP wizard popups
2. select the current renderpipelineasset by double clicking current HDRP asset in Project Settings > Graphics
3. in inspector, check the cache settings of the asset at the bottom (expected to be greyed out since VT is off)
4. toggle Virtual Texturing support = on in project settings > player settings > other settings
5. restart (or save and restart)
6. check HDRP asset

Expected: VT on = HDRP asset VT cache settings are editable, VT off = HDRP asset VT cache settings are greyed out
Actual: VT on = HDRP asset cache settings are greyed out, can't edit

Repro: 2020.2.0a20 + HDRP 10.0.0-preview.27
No repro: 2020.2.0a15 + HDRP 10.0.0-preview.1, HDRP 8.2.0

- MacOS only
- In 2020.2.0a19 may see slightly different actual result: VT off = error when selected HDRP asset and broken UI in VT cache settings in inspector

Workaround: add or remove a "scripting define symbol" in Edit > Project Settings... > Player > Other Settings > Scripting define symbols, then click "Apply" - this will trigger a reload and ensure the correct state for Virtual Texturing support. You can use any text for the "scripting define symbol" just to trigger the refresh.

  1. Resolution Note (fix version 2021.1):

    Verified fixed in 2021.1.0a7 with HDRP 10.2.0

  2. Resolution Note (fix version 2020.2):

    Fixed in 2020.2.0b13

    Virtual Texturing Cache Size settings no longer appears greyed out after enabling Virtual Texturing support and allowing editor restart
