I cant get my slk editor to work.

I looked in the Faq. at the top before saying this. i tried to change the lightning splat data thing. see i extracted splat data and i opened w/ the slk. editor in w3m map utilities. I edited it so that chain lightning was red and not blue. I saved it and put it into my map and it didnt work. i used file path splats\lightning.slk Well i then went to try it again and the slk. editor didnt save it. i saved it like 3 times on dif. deals the same thing. How come the slk editor wont save my changed things.

Well, that it doesn't work in game doesn't have to mean that the SLK editor didn't save your changes.

LightningData.slk is strange anyway. Many values in there are overridden or influenced by other files.
For changing the color of lightnings I'm quite sure that the color values in LightningData.slk don't do anything. You have to replace the texture for that lightning spell by a red version of it.
