Train Simulator Engineer crashes 8.1 (Resolved)

I believe I have this resolved. I definitely have what Paul describes resolved.

I first tried creating an engine using the default values and then by selecting a default engine from the list. (both 4-6-2’s) The engine created from the default values had very small bogies under the main drivers. The selected engine looked normal. When I selected the animation button and clicked play, the animation was corrupt (both engines) and after a few seconds I received Runtime errors ‘440’ Automation error, ‘30010’ Invalid Column Value, and then ‘0’ at which time 3DC locked up and required opening the task manager and ending the process.

Looks like a bug in 3DC 8.1 animation.

I used my rotate 360 Z script.

I added 1 cube to a scene, the added another cube as a child.

I selected the first cube and ran the rotate 360 Z script.

On the animation toolbar timeline, all looks normal. 5 Keyframes on the first group and none on the child group.

However if you run the animation once, a seemingly random number of keyframes are generated for the child group.
This is probably what is happening with the rod animation.

The train sim engineer animation code has not changed in 7 years <!– s:) –><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="" title="Smile" /><!– s:) –>

Thanks Paul. I realized after I made the post that I should have been more explicit. Train Simulator Engineer did not crash 3DC, but the running the animation of the models created by it did.

I’ve played with the Train Simulator Engineer some more and have found that if the engine created is saved and I exit 3DC, restart and load the engine, the animation does not crash the program. The animation is still corrupt and by that I mean the main wheels rotate but the rods rotate 360 degrees with the wheels they’re attached to.

I’ve loaded 3 different models I animated in 7.1.2 and the animation is fine in 8.1
