I don't understand why, but I started to weight paint my model and up pops a little hole in the shoulder of the horse. Please someone help.
It might help to post a screenshot of it in weightpaint mode so we can actually see what you did.
Or just upload the .blend file.
I tried seeing if using add would fix the problem in WP but it still proceeds and now I have a spot on the shoulder where the hole is..it also shows up in the weight paint. I just opened blender so the mix brush is showing.
ccgipaint It looks like that Vertex or those few vertices are either in a group that got auto-weighted to a bone or the rig
or
you assigned those vertices to a bone by weight-painting them.
Turn down the Weight from 1 to 0 in the toolbar on the left and paint over that area until it's blue. That should remove your dent.
