EDIT: Never mind. I decided to quit without saving and start again.
I’ve come accross a bizarre problem whilst modelling. I’d just merged two pieces of a model together in edit mode, and clicked ‘recalculate normals’ to correct the shading, then when I switched to object mode an enormous extrusion had appeared, which stretches almost indefinately. I thought it might be a simple weight painting problem, but the appendage isn’t visable in weight paint mode or edit mode I’ll attatch a screenshot to further illustrate the problem.
Thanks in advance for any replies!
