found out that the alpha of an entitity with a value below 2.5 makes it invisible.
So you can't fadeIN clouds - they are shown first of all when they reached entity.alpha > 2.5
This is bad for finetuning of skies...
example:
// The Sky entity the_sky1 { type = <the_sky02.tga>; layer = 100; // display above view entities & PANELS with layer 1 view = camera; // same camera parameters as the default view }
...
the_sky1.x = sky1_temp.x; the_sky1.y = sky1_temp.y; the_sky1.z = sky1_temp.z; the_sky1.transparent = on; the_sky1.alpha = 0;// 2.6 = SCHWELLENWERT ab dem ENT sichtbar wird the_sky1.visible = on;
I have not noticed it, but isn't 2.6 a very low, almost invisible value? Anyway if this happens on your 3D card there's probably no workaround, except maybe for giving your sky an already-transparent alpha channel texture.
