Wireframe on Blender not showing over whole object

So I sculpted this about a month ago and I’m trying to go back on it to texture it, then I see that the wireframe for some reason isn’t showing on the full object as seen below.

And when I go to wireframe mode, this shows up. I have no clue on why there’s no wireframe for the WHOLE object.

And yes there are a lot of verts on this object, I will reduce it before I upload to Roblox Studio. (I’ve already uploaded it non-textured)

Are you entirely sure this isn’t an assembly of different parts? In that case, it would be obvious why the wireframe only shows on one mesh detail, rather than the entirety. Otherwise it’s something else I might have overlooked.

I think I do recall separating parts of it, either way it’s all one object now. Weird thing is, whenever go on edge selection mode it looks like this:

And whenever I go on face selection mode it looks like this:

This is so weird.

That’s a lot of verticies, yikes. Try to cut down the amount of verticies without impacting the quality as much as possible and see if the problem persists or not.

Alternatively, look for the setting of Draw All Edges.

Neither of those work. I also tried to use the Triangulate modifier to see if that would help, but ofc it doesn’t. I’m about to just give up on it haha

It might be the complicated geometry that is technically ‘invalid’, I’m not entirely sure on that, but there’s just too many verticies and some of those may have edges sharing multiple faces than two.
