Wow thanks for taking the time to do that! Maybe I didn’t explain well enough what I mean on the axis, BUT thats really useful for the camera when I get to that!
Instead of the Z I meant the character can take the X and Y on the spline, so the character can move along a curved road for instance with the camera maintaining its relationship to the character as it would round a corner. My current set up for the character is very similar to the camera in your example.
Would you not foresee problems when it comes to blending a characters movement along multiple splines, or blending between running on a spline and then pushing an object?
