I can work around this, but Id like not to have to do so every time this arises…
After a few operations on the inside surface, the outer rim shows subtle triangular patterns. This happens in the upper and lower outer quadrants of the wheel, exactly 90 degrees each, at a 45-degree angle.
I’ve repaired the damage through substitution with an early, untainted version, only to see the patterns re-emerge after resuming work. For now, the solution’ll be to make the substitution last, as this has proven to work.
It should be noted that the distortions aren’t structural, per say; None of these show up when toggling the “Show/Hide Geometry” button.
But I’d like to know if and how this can be avoided, specially since it might give me an insight into similar problems I keep encountering.
As usual, thanx…
