Problem with editing *.nif

Hello,

i hope you can help me.

1. The Goal:
I planned on adding new building, which would use the same appearance of an other building but with slightly altered colors of its glow.


2. What i have done:
First i implemented the building in the *.xml files. I then went ahead and unpacked the art files via the PakBuild, loaded up the *.nif of the buiding and -for testing purposes- did not alter a thing. I saved the file under a new name (the old file was unaffected) and used the PakBuild to compress the art folder. I then made sure that the new building would use the new copy of the old building.





3. What went wrong:
The Building was displayed ingame as a purple ball




4. Further Question:
How can i edit the colors? I just wanted to make the glow of the building seen above more red, instead of white / blue. How does those triangles work (as seen below?)





my very thanks

Update:

i found out why it would appear as big pink blob: the textures where not carried in the new folder if i save it in the same folder it works.
however there are still some problems:

the color of the building changes over time (animation):
when i edit the colors of the corona and the flames it only changes them in the beginning


of the animation and i don't know where i can modify the color change gradient (i.e. in what color it morphs into)

update 2:
I created new textures with a new alpha channel but those had no effect on the glowing orb itself. (although the new effect looks good)
From playing with various options in the nifskope block details i know that 11NiMaterialColorController and 12NiMaterialColorController somehow determine the glow of the orb, yet i still can't figure out how exactly and i have not found any tutorials regarding this on the internet.

i finally got it to work, yay!
although i may tweak the effect a bit more

looks interesting
