SetTexCoord - Creating a Weak Aura icon that is a wedge

Hi Friends,
I have attempted this on my own but unfortunately I am at a loss. I am attempting to create a Weak Aura for my Outlaw Rogue which is comprised of 6 wedges creating a circle where each of the wedges is one (part of) of the buffs that can be gained from Roll the Bones.

Most of the Weak Aura stuff I am able to do but I am having issues with modifying each Weak Aura to be displayed as a wedge. I believe that using the SetTexCoord API would be required for this, but I do not know how.

Any help that could be provided would be greatly appreciated.

Cheers.

I could very easily be wrong as I’ve only worked with this once, but I’m not sure that can be cut diagonally, which would be needed for a wedge.

What I would do is just make my own texture that’s a wedge and have it display that.

I don’t know WA but if it supports MaskTextures you might find something useful here:

or maybe with SetMask (I’m not sure if the pre-defined mask requirement still applies)
