Jump Gate texture - how to replace/adjust it?

[MarStrMind]

I am trying to figure out where exactly the game is hiding away the standard Jump Gate texture. You know, this green-ish whirl inside the circular structure. I may have found a suitable candidate, but first I wonder if anyone knows where that may be. I can edit DDS textures and bring them into the right format. I just need to know where it is

Many thanks all.
