Unity3D - Make texture edges not stretch

I've been searching around for this one for a bit, and unfortunately I can't seem to find any good, consistent results. So, in the Unity UI system, buttons can stretch without becoming pixelated or distorted. This is because the texture is split up into 9 parts - the corners, middle, and sides.

enter image description here

This works because the button's middle and sides are stretched, but not the corners. Then, the button appears not pixelated, at any dimension.

So, the question is as follows: How can I do the same thing for a transparent, unlit texture in 3D space? I have a speech bubble texture on a flat plane that I know how to re-scale to fit the text in the speech bubble.

I've set the texture type to Multiple Sprite, and divided it up into 9 parts. However, I cannot seem to find where I can set the texture to act like the UI button does, and I'm not sure that this is even possible in this way in 3D space.

Viewing the speech bubble object Viewing the speech bubble sprite

Is there a way, or should I just make the different parts of the texture different objects, and move them together? That would seem very inefficient and ugly compared to this.

To accomplish what you are asking, you would need to create tiles for this speech bubble and then write a script that procedurally builds a speech bubble based on the plane's scale value. You could also try just changing the texture's Filter Mode to Point.

However I really don't think you should be using textures for this anyway. Why not just use a Unity Canvas and set the Render Mode to World Space? Then you can just set your text box to be a sprite, not a texture, and set its filter mode to Point (See below). This would also make it a lot easier for when you want there to be text in the speech bubble later on.
