random spikes jutting out of mesh im working on a realistic human head i dont know why this is such a common problem for me when the mesh creates random spikes in the case they come out of both ears. i checked in edit mode and the geometry seems to be fine with no loose vertices or whatever. i know this is something to do with the multi res mod but when i do a search i find useless answers that dont help
I believe it's a problem on normals. Visualizing the Normals at the [Properties Region] -> [Mesh Displays] revealed some peculiar normals.

At the same time, recalculation didn't work properly showing that you have topologically wrong faces. (Actually I found some but it's too tedious to name them. Add comment if you cannot find any)

Hope it helps.
