Bug Built in URP shaders are casting shadows when shadow casting is turned off, even with transparency

    I've been switching around to different URP shaders trying to figure out which one actually works with no shadow casting. We have a baked light only scene, no realtime or dynamic lighting, however our transparent objects on this fbx always have this full shadows behind them even with shadowcasting turned off.

    Were using opengl renderer currently since we are building to android devices and gpu progressive lightmapper to build the lights.

    Technically this is not a shadow, but baked lighting, and "Contribute Global Illumination" is still on.
    Don't have time to check right now, but maybe that's it?

    Well yes, we still wanted it to receive shadows during baking, we just didn't want it contributing any shadows towards it.

    We found a work around by setting them completely alpha transparent during bake and then returning them to normal afterwards, they still received shadows and didn't cast any shadows onto any other surfaces.
