Unity 2018.3 b7 - remaping materials during multimaterial FBX file import results in crash

    Hello, after upgrading to 2018.3.b7(Win10, LWRP) I have discovered the following strange behavior/bug:
    When importing fbx file containing more materials (tested with 3) and trying to remap the materials shown in Import Settings to those already existing in Materials folder:
    - First material remaps ok
    - When second material from Materials folder is dropped into the appropriate material slot in Inspector/Material Import Settings, Import mode deliberately changes - the toggle "Import Materials" gets unselected
    - When trying to toggle "Import Materials" on again, either nothing happens or - mostly - crash follows.
    All materials are "default" LWRP, just various colors to make visual difference.

    Exact procedure described in attached picture.
    The b3, which I used before upgrading to b7, worked quite ok in this regard.

    I wander if anybody has (had?:) ) run into similar problem? The bug makes any serious work with b7 almost impossible. Your experience/comment would be welcomed

    Regards
    IvanK

    Can confirm similar issues with fbx imports.

    Yeah, this happens to me as well.
    One material remap is OK, trying to add a second one results in a crash.

    In the meantime, until a fix is available, editing the model's meta file directly seems to work if you need to access the settings somehow.

    Same problem.
    Can also confirm that we can only remap a maximum of 1 material.
    I uploaded my project as a bug report, but then I found this thread.
    Beta 8.

    Did anybody submitted a bug-report for this problem? If so, please post the bug-report ID for Unity staff to pick up.

    If no bug-report was submitted, I guess Unity Technologies isn't spending much time on issues they don't have a report and project to reproduce the issue and test their fix against.

    Mine is 1096609.
    I would like to follow up, but this website "Fogbugz" requires a paid account to log in?
    Im not even sure Unity is using this website anymore, I have an open case from 2014 why arent they closing it?

    As far as I know, Fogbugz is their 'internal' bug tracking site – you can't browse through the bug reports of others unless they give you the direct link. If Unity decides it's an issue worth investigating, a public report is (usually) created and you're sent the Issue Tracker link.

    I just had a bug report about which I didn't hear since summer closed without an e-mail notification; so they do go back to close cases. But 2014 is a long time ago and from this ancient article it seems like they were unable to respond to even a fraction of the reports back then, let alone go back and close them.

    Hello, It seems that our bugs are similar, every change that is "multiple" results in a crash for me.
    Case 1097929 and case 1097932

    You can workaround by editing the meta file with a text editor
