Hello everybody,

in some shape codes (uncompressed s-files) I have seen at the end in the second to last line the entry "animation (0)". Does anyone have an idea which 3D modeling program could generate such line, although the shape basically does not contain an animation?

Maybe gmax or blender or 3Dcrafter etc ?

Greetings
Jonas

Hi Jonas,

I looked through a bunch of my work with 3DC - steam locomotives, tenders, freight cars, passenger cars, and static scenery objects. None have the term "animation (0) " anywhere in the shape file - - - steam locomotives are the only ones that use the term "animation" but that sets the speed based on the keyframes of the animation as the second line below illustrates. It's also located in the middle of the file.

There is a program that adds such lines, but I don't remember which one

I have a shape file created with blender 2.79 that has that line, and I also have shapes created with blender 2.82 that do not.

The MSTSexporter for Blender 2.8+ Release V4.3 checks to see if there is an `animations(0)` result and won't write it to the file. It will create/export animations entries only if the animations count is greater than zero. If you have a version of the exporter of 4.0 or older, it still will write `animations(0)` as far as I can tell.


A comment from the file:
# ShapeViewer crashes if you have animations( 0 )

Thanks for the replies guys so far!

So it seems to be the exporter 4.0 or older from Blender.
