thanx warcow for reaction. to export as wavefront was not the problem 4me, but is there any method in poser to make an object follow a path and i do not mean to make a figure walk along a walk path with poser integrated walk designer.
for example i have a railway with curves and parts going up and down and a locomotive should follow that railway automatically.
to place the locomotive step by step correctly on the railway up to 3000 frames and more would be a work for about 200 hours i guess.
by the way, if the 4 spline methods in poser work as they should.
