How to recalculate the automatic weights for single bones in blender 2.8 I'm trying to weight paint correctly and quickly a 3D character in Blender 2.8. I have rigged it with auto-rig-pro and then I used the addon "Voxel and Surface Heat Diffuse Skinning" for the weight painting. It did a good job,except for the teeth. Infact when I open it,this is what happens :



Since I've switched to blender 2.8 recently,I still have to learn it. I would like to recalculate the automatic weights only for the bones which have a wrong weight. So,I pressed the W key,but I don't see the entry "Assign automatic from bones". Where is it ?
You will find it in the Weights menu. Upper left corner of the 3D view.
