Get vertex position after flex

[Anonymous]

Hi,

Simple problem, no idea how to solve it 😉

A line shape has a simple flex modifier applied.
When I try to get a specific vertex (6) position with getKnotPoint $Line01 1 6, it always returns the vertex position without having the flex modifier applied.
I probably need to run the getKnotPoint on a edit_spline modifier after the flex modifier?

Any idea?

Thanks,
Davy

See if this thread helps any.

No, not really, I think mine is really Flex related.
Flex updates the line but when using getKnotPoint, it doesn't go all the way up to Flex so it results in the line vertex position without any Flex applied =(

Don't ask me what happened there - completely the wrong thread...

I've edited the post above to have the correct link - apologies about that.

Nope, that's about vertices from geometry while mine is from a spline.

I don't understand why it won't get the correct vertex position after flex is applied. Looks like flex does not affect the reall position from all vertices?

I don't understand it either, but that is why (in the other thread) the solution is to take a snapshot - which does happen at the top of the stack and therefore includes all the changes made by the modifiers.

Ahhh - I knew I'd seen this question before - area.autodesk.com/forum/Autodesk-3ds-Max/maxscript/solved-obtaining-coordinates-of-a-spline-vertex-affected-by-flex/

Sweet, works like a charm...

Thanks a lot,
