Hi Mauricio,
to make the spline points the same distance just
1- go to “MoGraph” then choose “Mospline”
2-in “object” change the mode to “spline”
3- in “spline” change the generation mode to “Even”
4-put your spline in “source spline” (drag and drop)
5-click on Mospline and make it editable (ctrl *c)
like in the screenshot below
hope that will help
thanks
