| Hello,
|
| I just wanted to throw some ground fog in my scene and therefor read the
| docs about this again. Is it possible that they mix fog_offset and fog_alt
| in some points?
|
| They say, that the fog below fog_offset is constant and fades away with
| fog_alt. But little later there is this sentence:
| "At an altitude of Fog_Offset+Fog_Alt the fog has a density of 25%. The
| density of the
* fog at height less than or equal to Fog_Alt is 1.0 and for height y less
than *
| Fog_Alt is calculated by 1/(1 + (y - Fog_Offset) /
| Fog_Alt) ^2).
| But the fog should be constant below Fog_Offset, not below Fog_Alt?!?! Do I
| miss something (it's already late ...), or is something mixed up?
I believe the excerpt part might be wrong and was meant to say fog_offset
instead, so yes, I will agree with you.
