[LWRP] Texture gets unassigned on updating Lightweight RP package

Package: SRP Lightweight Template


The texture gets unassigned on updating Lightweight RP package.

Steps to reproduce:
1. Create a new project with Lightweight RP template.
2. Go to Window > Package manager > Lightweight RP.
3. Update package version from 5.2.3 to any higher version (ex. 6.5.3)

1. By default, package version is set to 5.2.3 which is marked as 2019.2. verified.
2. Editor crashes on updating Lightweight RP package in 2019.3.0a1, so unable to reproduce it in 2019.3.
3. Video is attached for the reference. (LWRP.rar file)

Actual result:
The texture gets unassigned on updating Lightweight RP package.

Expected result:
The texture is assigned and rendering as expected even when the package is updated.

Reproducible in: 2019.2.0a13, 2019.2.0a1

Not reproducible in: 2019.1.0f2, 2018.3.0f2

Environment: Mac and Windows.

  1. Resolution Note (fix version 6.7.0):

    This was caused by the upgrader not being kicked off automatically in some cases. We fixed the upgrader to kick off always in 6.7.0 version. For the ones that can't upgrade to 6.7.0 the solution is simple. Just reimport all materials and the upgrader willl run.

    This was caused because the upgrader was not kicking off in some cases. A fix in the upgrader will be available soon. Meanwhile, in order to make it work you just need to reimport all materials.

    For anyone needing it, here is my workaround:

    ***Backup first***

    From working 2018.3 project

    open windows command prompt (with admin privileges)
    ROBOCOPY "source\Assets" "tempdestination\Assets" *.mat /S /IS /IT

    load up destination project in 2019.1 (or your new version of LWRP)
    Wait for unity to process everything and have it come up with all materials grey

    back to windows cmd:
    CD /D "destination\Assets"
    DEL /S /Q *.mat

    check back on unity, all materials should be gone and everything turns pink.
    back to windows cmd:
    xcopy ""tempdestination\Assets" "destination\Assets" /k/r/e/i/s/c/h/f/o/x/y

    check back on unity, it should process everything and you are ok.

    (make sure you have a backup project in case this messes up)
