Graphical Rendering Issue

[Wolfyard]

Mainly seems to be happening with RailX, as when it's disabled, no problem of the kind occurs.

Produced on Neoforge 1.20.1, Create 6.0.8, RailX 0.1.2-build.0 on PrismLauncher

As seen in the above images, the track itself is rendering outside of the track block. This makes the train look like it's falling off.

It seems to be caused by Create itself, where BezierConnection.Runtime is assymetrical for their handles.
Please try enabling server.fixTrackBezierAsymmetry option of RailX, then run again. Note that it patches (although small portion of) Create BezierConnection code, so all curves like this would be affected, meaning curve shape or train position of previous world can change.

Wasn't able to produce on the same survival world, as that server currently isn't up, but a creative testing world of my own has the same problem. Same specs, Neoforge 1.20.1, Create 6.0.8, RailX 0.1.2-build.0 on PrismLauncher.

Bug still occurs with Fix Track Bezier Asymmetry enabled via the server config, notably after restarting the game. Unless I'm missing something and it's not readily available through the in-game config, this option doesn't seem to work.

Could you tell me exact placement of tracks? i.e. K14 -> K29, delta=[5,0,-14]
Also, does F3 debug overlay or signal overlay show same weird line?

I thought Fix track bezier asymmetry option that you turned on should've fixed that issue.

[Wolfyard]

Creative testing world again! Same specs as always.

I'm not sure if the station overlay was what you wanted, but it might be helpful?

[lhwdev]

Sorry, I meant something like K14 -> K29, delta=[5,0,-14] in exact numbers. Could you measure that for me, so that I try same placement on my computer and debug codes?
It is very hard to replicate these bugs by eye.

[Wolfyard]

If i got this right, it's K32 -> K48, delta= [118, 0, 49] This happens on the creative testing world, at least, and there are different ones I can give you if I get on the original server.

For context, here's an overhead view facing east. The tracks themselves go northwest.

[lhwdev]

I'm sorry for being late for this issue. Have you tried restart your singleplayer world after enabling Fix track bezier asymmetry option?

[lhwdev]

I think this turn is illegal? This shows 'curve too steep' for me.

[Wolfyard]

I mean the sleepers are fixed and don't do that weird spacing issue anymore. The hitbox isn't though. Note the train isn't on the track, as Create thought the curve was non-existent, and refused to drive on it. It also crashed my game when removing the curve, soooo, I don't think I'm supposed to use the split-graph track. It also crashed when placing normal train track where the split graph train track had been. ._.

[lhwdev]

it might be fixed by latest release, would you try that?
