Textures, Reticles, Animations

[Ermac]

1) Where can I find the reticles for other weapons / covenant weapons? I opened the regular reticles texture and only found the AR, Pistol, Warthog, and No Ammo ones.

edit / Actually ignore #1, I figured it out right after I posted, My Bad. / edit

2) Is it possible to animate a reticle? Any hints / suggestions? Would I have to edit the texture, or is that done through shader's?

Thanks
