I am in the process of UV unwrapping a rather complex model that I have spent the last few weeks working on. However, at one point this evening whilst trying to make some progress on my project, I found myself unable to select individual vertices by right clicking them. I am still able to select individual faces by selecting the face select tool and right clicking on them, but for some reason I cannot do the same with vertices.
I am aware that one other person had a similar problem with blender 2.7 which turned out to be caused by the "UV sculpt" tool, but no such tool exists in version 2.46, which I am currently using.
This issue only affects the object itself and does not affect any other objects in the scene. I thought that I might be able to Rube-Goldberg-fix the problem by joining the affected object with a non-affected one and vice versa, but this only led to the problem "infecting" the other joined objects regardless of the joining order selected. I have also tried importing the mesh object into a new file, but the problem seems to follow it when I do.
I am now at a stage where I can either scrap the whole model and start over, or find some way of fixing it. Since the model represents quite some time investment from me, I would loathe to have to start over and so come to you, cap in hand, pleading for help with this project-ruining issue.
Thank you all in advance for your assistance.
