MSTS .s files no longer loading in ObjectViewer

[soyachoin104]

At least since the March nightly builds (currently using the 23rd March build), MSTS .s files no longer load in openBVE. Attached is a screenshot of the error message. What could be the problem?

Thanks

I can't reproduce this.

Please can you link me to the object file that's no longer loading. (It's probably animation related)
There have been a lot of internal changes with regards to MSTS objects to support animations.

That's an interesting one.

MSTS expects the bogie matricies to be at BOGIE01 BOGIE02 etc.
This object is using an underscore to add additional comment data at the end, which I wasn't taking account of. This now works, but the object is definitely rather slow. (~5fps here, and this is with a 3060)

Loading a 47mb textual file isn't clever either.

Let me do some more work with this one and see if I can get things any faster.

I have noticed that models built for OpenRails are built a little differently to older MSTS specific models. I don't know if that has anything to do with the problem?

Possibly, I haven't really investigated the differences.

The build from today implements face squashing into the shape parser itself. This makes your model run in the simulation at a sensible speed :)
(It's still rather slow to load mind)
