Have a question about blender, this is still WIP but the model I use never had toe bones, just ends at the feet, so I'm manually adding toe bones and weight painting them to each toe. The bones are easy enough to add and parent...but I could really use some advice on how to weight paint these.

The problem being that the toes are so close together (like in the pic) that it's making it really difficult to weight paint each individually to their appropriate bone, because the other toe is right next to it and will accidentally get weight painted as well. I'm sure there's some option/toggle or something that can make this more manageable because right now it's impossible to weight paint them individually without also accidentally painting the toe next to it and fucking it up
