    In this one area of my map I have the auto-generated grass sprites very dark - basically black.[​IMG]
    not exactly sure why this happened. The area is pretty lit by the skybox above it. I had a theory that since there were 0 other lights in the scene, that somehow contributed. I was incorrect.

    It's only in that area though. In a different area they are normal[​IMG]
    same texture used, different places in the map, enclosed by different brushes and skybox brushes.

    It seems the problem was caused by the area receiving extremely dark lighting from the skybox.

    Although the area was bright for me, HDR lighting brightness was set to 1, and compiled with hdr.
    For some odd reason, my game didn't see the hdr skybox lighting, and saw it with the other skybox brightness of 250.

    Thus the sprites were dark but the area was bright.

    the sprites from the second pic were lit with light entities, thus had normal brightness.
