3dsmax Question about Surface+Paths

D4V1DC

Okay,

To make things easier for all here is an image to briefly explain:


I got the Iris to follow the path constraint, now I need the iris object to follow the surface of the eye ball and I don't want It to clip through the eye ball object.

This is the video doing the wrong thing:


Ignore the odd glitch were It returns to the front every few frames the video is smooth across this is just an example of what I am trying to avoid/fix.

How do I do that?

Just tested a few thoughts on this. One way that looks nice is:
1. Create a NURBS ellipse path on the sphere (I did this by creating a spline ellipse, converting to NURBS, then moving the CVs manually so it aligns with the surface of the sphere, but there might be a better way - e.g. cutting the path into (a copy of) the sphere and creating a shape from those edges, then converting to NURBS)
2. Path constrain your iris to the NURBS ellipse, and turn on follow.
Hey Presto!

Thanks for the info that worked out well, I know this may have been easy for most but I don't dab to often into these things I just usually model. This is for a personal project I wanted to learn something new.

Thanks for your help.
