The other day i wanted to start implementing trees, so i did but i wanted to make the trees fade out if they were far away, and when i want to do grass i want to make them fade out into nothing so it seems abit more realistic (and that the person doesnt realise so much that the grass is only being displayed where they are).

When i do dbGhostObjectOn for objects created in TreeLife (havnt tested in plantlife but i guess itll be the same), it does nothing, the object stays at 100% opacity and you can see clearly now the rain has gone.

Is there any alternative that i can use to fade objects created in these applications?

Thanks in advance

use dbAlphaMappingOn ( or dbSetAlphaMappingOn ), if i remember well, it has a parameter to control object's alpha, make far objects have low alpha, the following pseudo code would help:

if ( object closer than x )
{
if ( object farther than y )
set object alpha, you can use x-y and map it to 0-100 (the function range)
}
else
hide object

x is the far plane (where you want your objects to "disappear" after it)
y is the near plane (where you want objects closer than it to have full alpha

Oh nice thanks, ill give it a shot and edit here how it goes.
Thanks.


I dont think it works how i need it to.
i set the mapping to 50, all trees were invisible.
i put it to 90, all trees were completely visible and solid
i put it to 80, all trees invisible again.

Took out dbSetObjectTransparency (499,4);, to see if it caused the problem, but now it wouldnt change visibility at all.

Finally changed it to dbSetObjectTransparency (499,2); (with other variants) It does do transparency but it leaves a distinct white outline around the leaves and trunk of the tree.

Is there any way i can fix this?

[edit]i made it dbSetObjectTransparency (499,10); it still leaves a white outline but its livable, thanks dude.
