Quote - Les, I forgot to thank you for this tip. Does the modified geometry have to be in effect whenever the walk sequence is used, or only when it is created/constructed? Would it be possible to use a morph instead of a geometry switch?

I think it needs to be used whenever Antonia is used in the walk designer. There may be some other way round the problem, but if so I can't think what it is. Unfortunately you can't use a morph for this, as the walk designer does not "see" the morphed shape. A better alternative to my crude solution might be to add an extra polygon with transparent material.

I should probably not have sounded so certain about what I said concerning how the foot bend works in the walk designer. It's more of a theory than a proven fact, but it's the only way I can account for what I have observed, and extending the foot does seem to solve the problem. So that's strong evidence that the theory is correct.
