    Hi,

    I am unable to use MSAA with transparent objects in HDRP in unity 2019.1.3f1.
    When I enable MSAA within forward, transparent objects disappear.

    Steps to reproduce:
    1. Create HDRP project
    2. Add object with Lit shader set to transparent and set its alpha in albedo
    3. Change lit shader mode in hd render pipeline asset to forward only
    4. Set Multisample Anti-aliasing Quality to MSAA 8x
    5. Enable MSAA within forward in hd render pipeline asset

    After 5-th step, transparent object disappears.

    Is it possible to use MSAA in HDRP with transparency?
    I used it with success in non-HDRP project.

    I have similar issues in URP project in 2021 LTS version. Not sure have to do something with my platform type (Mobile VR platform) toh ;(
    Are you able to resolve this?

    In my case, I have world space UI with transparent borders and couple of unlit materials which are of transparent render mode, which does not render in final build once MSAA is set to anything above none option. (PS: I can see the UI and transparent materials in editor toh).
