Please see the attached screenshot. I am following Grant’s Modular Dungeon tutorial and trying to merge the two sets of vertices as explained at about 6:50 in Lesson 2.2 (Creating a Barrel). However, merging removes 146 vertices, despite the merging distance being very small. I don’t see any change in the geometry, so I don’t understand where all these vertices are being removed from or why.
Any suggestions would be greatly appreciated.
