HDRP baked spotlights: restrictions? bugs?
OK, I have made a scene (HDRP) with a set of spotlights in a grid. They are all identical: static, mode:mixed, volumetric off, shadow map on. When I bake the lighting, I get random results.
The good ones show a large "spot" on the terrain. When I toggle the enable checkbox in the Inspector, the spot goes on and off. Scripts can control the intensity.
The bad ones have a small spot. Toggling the checkbox has no effect. Scripts can't control intensity either.
Attached is the baked lightmap view and the shaded view. Any clues much appreciated. Using 2019.2.0f.1.
(I tried area lights too. They are a little different, but no better. And the light spread is too wide; that is why I wanted spot lights.)
P.S. If I change mode from "mixed" to "realtime", they seem to work. But it seems to sort of defeat the purpose.
