HELP! Camera flythru in a tube

[Chris Smith]

I would stick to what you did originally however, animate the camera using layers of nulls.

So:

Create a path spline, create your profile circle and use a sweep nurbs to create your tube. Duplicate the original spline and offset it so it’s centered up inside your tube.

Create a null and name it something like “dolly” so it gives you the notion that it is just something the camera will sit on. Now add an align to spline tag to the null and keyframe the position parameter over time. So the null should move through the tube.

Now you can simply put a camera in the null group, the camera will have it’s own rotational/position controls independant of it’s jouney through the pipe.
But what I do is add a second null in the first null group and put a vibrate tag on it and set the vibrate settings to make the camera jiggle. Then I group the camera under this vibrate null.

The point being is to isolate each layer of movement to it’s own null. So you have the dolly null, the vibrate null, then the camera itself. I even isolate the camera under one more null so that I have a third null that is camera look at or set it to target something, then I still have the camera’s controls left alone to do something with if needed.

I have a setup that most likely will help. Please check out SteadyCAM79 (last item on the page)

I have always just created a duplicate spline to the one my camera is on, and had a target null travel along the duplicate just in front of the camera….the camera always points at the target null just in front of it……which is of course traveling throught the tunnel…You can advance the starting point of the duplicate so that itis always one point in front of the camera..however if the points are spare, this will cause obvious problems….I find it easier to just stagger the animation keyframes just slightly between the two splines….

Hi,

I would just like to say that the tcaststudios SteadyCAM is an incredibly good plug in – a great way to set up shots very quickly but at the same time with a an array of adjustment options. I largely use C4D as a 3D storyboarding sketch tool and teaching tool – for which SteadyCAM now provides me with a wonderfully easy and powerful camera control. I heartily recommend it.

With thanks
