Well…I guess that’s something else to look for.
Yeah I must have accidentally set that. It’s not a function I normally use, or even know what it does exactly…. except produce poke-through.
You set smoothing…and that is part of the smoothing.
Basically it’s the same function as ‘bevelling’/filleting/creasing an edge in a modelling program…it preserves the edge ‘hardness’ (makes the edge sharp as opposed to soft and flowing).
