Spline twisting problem
show user profile  soontekk
Ever drawn a spline snapping to a 3d object's corners ?
It seems to rotate the vertices (possible ?) and when you set it to renderable, or extrude it or use sweep for instance, it twists the whole thing making it unusable.

I have been looking for ways the align the vertices so they act normally, no luck sofar.

Do you mean using vertex snap?

Just tried recreating it, drawing over a sphere.

My line rendered just OK.

Why not try selecting the edges you want and then Create Shape from Selection?

ill give that a go

make a random polymesh (irregular and maybe deform it a bit) and draw a spline over the vertices using vertex snap like you said

Don't have time to recreate it now, did you try resetting x-forms and make sure all the verts you were snapping to were welded? Sounds like an odd problem.

This is a general problem with splines in Max. I've run into it a lot over the years when using Path Deform and getting unpedictable twists and kinks. Never found a solution.

i know rite, especially considering max uses quats as the default orientation unit, all spline verts have one and it would be incredibly easy to just interpolate the 4th value but its just ignored. I suspect a programmer working on it back in the day went to buy a new pack of cigs and never came back.

Thx Lion, i didn't know i could create a shape from selected edges !! :o

Works better but still not correct angle
