How would i put an image on two wedges to make it split in half

the title is confusing, i know. i thought i managed to make this work however it turns out the other half is not really aligned correctly.

here’s a video demonstrating the effect i’m going for: (placeholder image)

however jt works here because the eye is symmetrical. as soon as we use any other image it looks.. like this

(you can’t really see anything because light affects it, i should probably use a surface gui for this however i suck at using them and don’t know how to make them stop when the part stops, hence this post lol)

you can see 2 roblox logos meaning the 2nd half is just the first half but upside-down which is NOT what i want. if i rotate it maybe it’d work but that doesn’t fix the whole lighting issue, which i think would be fixed with surface guis, but again, i really don’t know how to use them.
