Please excuse my ignorance, but I've searched this issue all over the web and have yet to find a fix that works. I'm a beginner working through a character modeling tutorial on YouTube and am at the retopology step of the creation process. I'm really enjoying Blender and how powerful of a tool it is, but occasionally run into a few roadblocks.
The vertices you see on the right side of the character's pants are being mirrored on the x-axis using the mirror modifier. I'm snapping the faces of the low-poly retopology object I'm currently creating (tan color over the pants)to the high-poly pants object (olive color). The vertices all seem to line up properly in the mirrored side (left) until we reach the left-most vertices that stick out and don't snap to the pant faces. I've checked that all objects are centered, have their transformations applied, and even tried making a new object (which displayed the same behavior).
I'd really appreciate any insight and advice as to how I can get the mirrored vertices to snap to the high-poly pants object like the original vertices on the right. I'm sure it's some simple setting or mistake somewhere, but I can't for the life of me find it. Thanks in advance!
