Shifting Start Position of Path Curve

[cosku]

Hi there,

How would I go about shifting the parameterization start-position of a path-curve?

It seems to always start from point #0, but shifting the point numbers doesn't help (see attached .hip),

and the curve doesn't have UVs either.

Thanks!

The easiest way would be: add a float to your expression, for example:

($FF/240)+0.22

I'm sure something could be done on the curve as well, but do you really need it there?

Hey Macha,

Thanks, but that I don't want to do.

I should've been more clear probably:

In reality I'm reading a speed graph through a .chan file in CHOPs, finding the area with an Area CHOP,

normalizing that to a 0-1 curve to use as distance, and feeding that to my "position" attribute.

Since I have this is place already, I'd like to just modify the path's start point.

(I can't shift the position graph in CHOPs, as the curve doesn't linearly smoothly fade out at 1 and fade in at 0,

and it jumps as a result when it goes past 1).

Thanks,

OK. Try a carve sop. Perhaps that works.

Ah! Yeah,

That did it.

Thanks Macha!
