Does anyone know how to change the alpha of a WED map enity like a cube or somthing?

You have to write a script. But you can make it customizable in WED easily.

Code:

---

define my_alpha,skill1;

// uses my_alpha
action alpha_entity
{
    my.transparent = on;
    my.alpha = my.my_alpha;
}

---

Then just input the desired alpha value in the skill1 parameter.

Hope that helps. God bless.

you could do this
action alpha_entity
{
my.transparent = on;//transparent flag
my.alpha = 25;//change this to your liking
}
i think...either that or just use the transparent flag if you havent done so already.
