I've been learning blender for a couple of days now and I have a problem that I couldn't solve. I'm following this tutorial btw: https://www.youtube.com/watch?v=XkiWBSSuxLw&ab_channel=Imphenzia. I selected the body and then shift selected the armature then CTRL + P and "Armature Deform with Automatic Weights" as he did in the video, but when I move the armature, the mesh doesn't follow it. It stands still. Here are some screenshots below.
Your parentage actually failed. What you need to do is:
- Delete all the vertex groups (in the Object Data panel > Vertex Groups list, down arrow button on the right > Delete All Groups)
- Some normals are inverted, select your object and in Edit mode, select all and press ShiftN in order to recalculate the normals.
- You have overlapping vertices, select your object and in Edit mode, select all and press M > Merge by Distance
Parent again, it should work
