This is the second video with the correct result

Correct result

Incorrect ResultHi Fredo,
AS stated before, the animator is a good program but I have BIG issues.
I am also willing to pay for the full version but only if I am sure it is working.
I have started several works and every time I close the work and Sketchup file; opening the file again the models have changed positions and movements are starting and heading in the wrong direction. E.g. I made the APPARITION of the pipework above ground in a construction site and TRANSLATION of the same pipework placing it below gound. Next time I open the file and activate Animator the sequence places the pipework in the correct position and translation it well below underground (disappearing below the same distance I selected in the beginning). Some other scenes disappear completely.
I have tried several approaches, changes of parameters, etc in Animator and wasted a lot of time trying to correct it. I can't find a solution to it even if, as said, I started from zero.
Fortunately I made a test video with the sought result and a test (1) video with the wrong results (2) see attached
I am using MacBook Pro, Big Sur IOS 11.4. SketchUp Pro 2020 and your latest (I presume) Animator 3.5a - 28 May 21 version

Im sorry I have to be so blunt but I need help solving this issue.
I appreciate your time and help.
Thank you
Rob
