I just use that plug-in for the first time and as usual with plug-ins, frustration rises from not being in control.
I have several cylinders in a comp and the idea would be to have a camera jumping from one to the other. SO there is depth in the movement.
I put my 7 cylinders comps in 3D, create a nul object and a camera (linked to the object)... but then when I move the nul object on the Z axis... all cylinders move (even though they are not parents) in a random mess.
Could anyone let me know how I can achieve that effect of havong a camera navigating between these cylinders?
I just tried it and it worked fine for me. Be sure you are applying the cylinder effect to the layers in the comp that has the camera to maintain the 3D perspective of the cylinders. If you apply the effect inside of a nested pre-comp the cylinders will look kind of flat. Also, don't move the cylinders by moving the layer. Use the position and rotation properties in the effect to manipulate the cylinders. Otherwise you will get unpredictable results.
If your still having trouble then could you post a screen shot of your timeline so we can see what's going on?
