Mirror Modifier not working as planned

[Kobps]

Hello, I was working on creating the knight and the mirror modifier doesn’t seem to complete the object all the way through. How can i fix that? Thank you

Hi,

In which course and lecture are you?

This is in the mirror modifier lecture on modeling the knight, here is a full screenshot:

I’ve just moved your thread to the correct subforum.

I think you need to use the y-ax instead of the x-ax (your using an old blender version)
Also, your object scale could be strange (merge limit). And you have the magnet EDGE option ON.

First of all you need the Y axis but that alone may not be all the issue. Have you applied rotations and scales? Object mode Ctrl A rotations and scales.

As mentioned by FedPete, you are using a very early version of 2.8, while I do not think it any problem with this issue, it might be better to move to at least the 2.83 LTS
