Dynamic tracks with positive angles renders wrong.

In msts:

Fix is easy, just use -radius for positive angle http://i.imgur.com/cnPtHmo.png

If you don't have route with positive angles in dyntracks, here is one: koniec.org/ccc_dyntracks.zip

Pls. open a bug report for this.

goku,
as I understand you have programming skills, you could have a look at DynamicTracks.cs and see if you can provide a patch.

[Lutz_s]

Maybe I missed something, but how do you define dynamic tracks with positive angles? The MSTS editor doesn't provide the ability to do this. So one could argue if it's really a bug.

That explains why it's not come up before and I can relax about this issue for 1.0. Thanks. :lol:

I think that absence of positive angles in dynamic tracks is just a bug in RE. MSTS creates track sections for both negative and positive angles and if you change angle value in .w file and sectionidx in route tsection.dat everything works fine in game and RE.
In my editor it'll be core feature for track placing.

Hi Goku,

Help me understand; By "positive" or "negative" angles do you mean track curve to left or right as viewed along Z axis from the shape pivot?

best,
vince

[Goku]

Yes. With negative agnle track curve to left and with positive track curve to right.

I thought that MSTS dynamic track only curved one way. To get an opposite curve you make a second piece and flip it?.

That's the normal way. Goku has implemented the dynamic tracks in his route editor with both directions. MSTS knew only left curves.

[eric from trainsim]

It's interesting to me that it took 10+ years for someone to try that, instead of just flipping the pieces...

Ah. That is why the error popped up. . I never did like the MSTS dynamic curve tool. I think I will give the new one a try.

[Goku]

I see this bug is still not fixed.

But now I see that not only shape rendering is broken, but track paths too. And I don't know how is it even possible? Why train does not just follow TDB and tsection path?

Example route that shows this bug:

http://koniec.org/cc...ntrack_test.zip

Two dyntracks are only rendering wrongly but third dyntrack "20m strt, A .500 100r curve, 20m strt" does something weird things with trains.*

Everything works ok in MSTS Game and MSTS RE.

* It turns out that weird train circles was TSRE bug wisible only in OpenRails.
Was:
TrackSection ( SectionCurve ( 0 ) 40038 30 15 )
Should be:
TrackSection ( SectionCurve ( 0 ) 40038 30 0 )

In MSTS and TSRE it was not visible, because these apps choose between line/curve by SectionCurve ( LINE/CURVE ), not second value.

The problem is probably in the Decompose method in runactivity\viewer3D\DynamicTrack.cs. Not sure I'll find it out, it's full of matrixes there :sweatingbullets:
