See the image: You can use Loft and twist to change the orientation of the spline. Add as many points as you want and start tweeking. Also, if I remember corectly you can add the same shape in the loft path in desired location and then select this shapes and rotate them. :)
ahhh! wow lol. didnt know you could do that. ive only really used loft in maya and i guess its quite similar in max. i managed to find a way to do it though. i just detached certain parts of the spline and rotated them individually, then once i put it to editpoly i rotated the ends that met with soft selection. though i…
Maybe you can do path deform to the spline from a straight piece with the same basic topology? This means you'll use an edit poly for it, but it's more control than a rendered spline in this case I think? If you still can't work out the unwanted clipping and way it's sitting, maybe using the path deform means you can…
