No leave the zombiedoctor_d2.tga alone just put where the effect is the following bit
effectbankcubeentcubeent.fx
Make sure there is a space after the = sign before you copy and paste the above
And then add the following line as in the code
transparency = 2
That way you will have a more realistic ghost character, and you could do the same with any other character as long as you have got Full shaders on
Just make sure its the same as code
I only put this part of the script to show which bits to change
I just felt abit bored so I played around with the scripts. I find it a good way to learn more about scripting. You never what you might come up with.
