    [RENDERING] Point Lights crashing editor

    UE version: 4.21.2

    We are disabling "Support pointlight WholeSceneShadows" in the project settings, this causes the editor to crash whenever a point light is dragged into the scene with shadows enabled.

    Disabling shadows in point lights in a BP and dragging the BP in the scene does not seem to crash the editor.

    However when checking with Robo Recall mod editor this option is also disabled in the settings and dragging point lights in does not crash the editor just gives a warning which is expected.

    The same phenomenon occurs for me. I don't know why, but if you activate WholeSceneShadows in project settings, no Crash will occur.

      I looked at this briefly and it is something shader related as it isn't able to find a Shadow shader that has WholeSceneShadows turned off or something like that. Epic would need to investigate this one as I'm not too familiar with the graphics pipeline.

        I need to have it turned off because I don't need light shadows and it says that it saves precomputations, as mentioned above I noticed their Roborecall mod was running on UE 4.16 maybe its a bug introduced after this version.

        For now I am avoiding any drag and drop point lights I am creating them in BP's with all shadows turned off before putting the BP in the scene, it's working that way. But yes it will be great if Epic can have a look at it.
