C'est à dire ?

Distant alpha doit toujours fonctionner avec transparency/opacity, sinon il ne fonctionnera jamais il me semble.

Citer :
New Prop: Renderer->"Distance Alpha"
------------------------------------

Distance based object alpha/transparency. This is used to make object transparency change, based on distance from
the viewer, to either become more or less transparent when the viewer moves away. The available parameters are:

"Near Alpha" - Alpha value to use when viewer is at a distance of "Near Distance" or closer.
"Far Alpha" - Alpha value to use when viewer is at a distance of "Far Distance" or further away.
"Near Distance" - Distance from object where alpha will be "Near Alpha", must not be larger than "Far Distance".
"Far Distance" - Distance from object where alpha will be "Far Alpha"
"Falloff Type" - Controls the curve that the alpha will fade based on distance:
"Linear" - Changes at a constant rate.
"Smoother at Near" - Levels out as viewer gets closer.
"Smoother at Far" - Levels out as viewer moves away.
"Anim Light" - Optional concrete object id of an object with the "Anim Light" property, where the brightness
of the animated light is used to control alpha. This is useful when a bitmap object is used
for light cone effects so that the light cone animates along with the light.
It can also be set to "-1" to let it use the object connected through a "DetailAttachement"
link as the anim light object. Especially useful when creating archetypes of anim light
objects that have linked light cone effects.

In order for this property to have any effect, the object also has to have the "Transparency (alpha)" property set.
The Distance Alpha alpha value is multiplied with the alpha from the Transparency property.

Tu as bien Render-->distant alpha
et --> Opacity/tranparency ? (même si c'est 1 pour aucune transparence, distant alpha ne fonctionne que si c'est propriété est présente).

Pour un SFX

Tu mets transparency/opacity: 1
distant alpha


Et la transparence est dans SFX avec alpha entre 0 et 255. Tu peux néanmoins utiliser transparency/opacity pour ajuster (même si en pratique ça ne sert à rien ou presque)
