    I'm trying to generate light maps with an area light (which is baked only), but I don't see any light output in generated lightmaps. I verified this by switching the viewport to "baked lightmap" mode. I do see some light output when using point lights in Baked mode. Are area lights not working in LWRP? I'm on 2019.2.0.a9

    I found that one way to get around it is to create a static emissive light in the shape of the plane. It's virtually the same.

    Also having this issue with 2019.1.2f1

    This is after manually baking. Doesn't matter if I'm using enlighten or progressive.

    This issue is going to be fixed in LWRP 5.14.0 for 2019.1 and 6.7.0 for 2019.2.

    The fix is available from LWRP 5.14.0 onwards for 2019.1 releases.

    Could you please update the editor to 2019.1.6 and then the LWRP version to 5.16.1 and see if this resolves the issue?

    Hello, I just found how to make area work with 2019.1.6f1 Updated the LWRP 5.16.1.

    Just create a Point light, baked, then switch to Area.

    Working in 2019.2.0f1 with LWRP 6.9.1.
    Switch your Area Light to Point, switch it from Realtime to Baked, switch it back to Area.

    Area light only works as Rectangle shape, not Disc, even when I've updated to LWRP 6.9.2. Could do with a disc shaped one please Unity!
