Im really impressed that you just commented on my addon lol, i always loved sligwolf's vehicles and some of them were the inspiration of making extremely stable and high speed trains. I also found a potential fix if a slider, bogie or train does that clipping glitch, the way that i fixed it is by making the concave thick enough until that glitch wont happen, it also appears to happen with really specific angles of that concave, it "errors" and then the model loses collsion. This also happens with the Sprops wheels too, so probably remaking the slider physics and test it until it wont happen again was my way to "fix" it. Though it still really annoying and this bug should really get fixed, i hope its not an issue with the main source engine

Hey RodrigosMOD!

Thanks that you liked my stuff that it even inspired you to make your own addon!
Really nice and a pleasure to hear!

It's great to see that you also try to make better sliders.
But the problem what Grocel meant is, even with the normal gmod props, you aren't able to build a train that is stable enough to stay in the rail. Which must undeniable have to work.
Especially, if this issue swaps over to the main branch of gmod.

And even people like you and me can maybe not fix that with our sliders.
Even if our sliders are maybe the finest that gmod will see.

Btw, I was very impressed of your train in the video!

@RodrigosMOD: I like to hear that our efforts are an inspiration for your projects.

At the moment the main branch is fine. Only x86-64 is affected. Unfortunately it is rather unlikely that you will be able to prevent these kinds of glitches with better models. Not without some heavy drawbacks at least. Trust me, we also tried.

Please see all the infomation posted at this issue here:
https://github.com/Facepunch/garrysmod-issues/issues/5968

It has all the information we could gather. You may want to add you own findings too. If you want, you may also reproduce the issue with your models and post a video to that issue. This is important to show Rubat and others the whole implications of that glitch.

ohh thank you! Yeah these things are a huge problem when it comes to trains, i hope it gets fixed because knowing that one model will not work properly in one server but it does in others, its really bad. I saw this issue happening recently on a train build server where my slider clipped through the tracks exactly like the videos that you made, where the steam loco clipped and jumped extremely bad into the air. But in other servers that are on normal branch that doesn't happens, i also testing my sliders again in singleplayer with the 64x bit branch, but physics are still "stable", the clipping thing doesnt happens but props tends to jump extremely hard sometimes, something that doesnt happens on normal branch. Really weird thing and my only hope it gets fixed. Big oof

If x86-64 ever gets merged into main like that, it will kill train building altogether. It's probably going to kill other large physics building communities too. Like gearwheel stuff and Wiremod v6 engines etc.

Our latest addon is affected by that too:
