Update: This problem is connected with the center of mass of the vehicle. After filling the containers, the center of mass moves behind the center axis and this causes the inverted steering.

I can also attest to this. I have a vehicle where both front and back wheels turn to rotate the vehicle. When the containers fill up the center of gravity moves behind the rear wheels, and the steering behavior changes so that all wheels move in the same direction, causing the vehicle to strafe, not turn.

It would be much better if we could dictate the steering direction instead of the game deciding for us.

This Bug is still present.

Hello, All!

Thank you to Local Yokel for bringing this to our attention that it is still an issue. I have tried with a few different rovers but have been unable to reproduce the issue with the containers in different areas. Could you please supply a rover that this is happening for you on?

After that just follow: \Roaming\SpaceEngineers\Blueprints. Select the correct folder where your blueprint is saved (local or cloud), zip the file and attach it here.

I tested it with the rover blueprint attached to this post. It seems like the problem is dependent of the Center of mass. The middle wheel axis is inverted, when the Center of mass moves behind this axis.


Settings:

- Realistic Inventory Size

- Filled Engine, Medium Cargo Container and Connector with ice

Hello, Local Yokel!

Thank you for the blueprint. Just to double-check, you have the center wheels set to invert. Is this happening when they are set to invert or when that is unchecked? So far, I have only got the center wheels to invert by filling the medium cargo container once the invert is switched off. Could you post some reliable steps for me to reproduce the exact issue you're having. I see quite a few steps were in the original video and wondered if you need to exit out the vehicle each time. Is this also happening with the amount of ice you put in the blueprint? I assume it is but can't seem to trigger this unless the container is 100% full. Any further help would be excellent :)

Kind Regards

Steps to reproduce the bug:


1. Spawn the Blueprint

2. Get inside the vehicle.

3. Turn on the engine with button 9.

4. Turn left and right (while standing) and observe the middle wheel axis. It is turning in the same direction as the front wheels.

5. Get out of the vehicle.

6. Fill the O2/H2 Generator, Medium Cargo Container and the Connector with Ice.

7. Get inside the vehicle.

8. Turn left and right again. Now the middle axis is inverted and is steering in the opposite direction as the front wheels.


If you now get out of the vehicle and empty it, everything is normal like in the beginning.

Hello, Local Yokel!

Thank you so much, those steps were excellent :) I have successfully reproduced the issue and reported it internally. I really appreciate your help!

hello

dear devs!

please let the player decide whether both the propulsion, and the steering of a wheel suspension should be inverted, or not by hand, do not set these things by default as the player is placing the suspensions, or the player is making the center of mass to be at a different place by accident

only set default inversions on wheel suspension placement, do not update it, and on placement set the default inversions the way that it is reflected by both the "inverted propulsion", and the "inverted steering" checkboxes of the respective wheel suspensions' terminal configuration

Hello Steven,

Thank you for reaching out to us on the forum.

Could you please confirm if the issue you're experiencing is the same as the one reported in this thread?

I will check, but it seems to match

Hello Steven,

It’s been a while since we heard back from you.

Could you please let us know if the issue you’re experiencing is the same as the one described in the report we shared earlier, or if it’s something different? If it’s not the same, please share the information we requested in our previous reply.

Kind Regards,

If the center of mass is between two axles, steering tries to pivot around that. So if say ore is collecting at one end or the other the center of mass will move that way, and if it passes an axle that axle's steering will invert.


It's almost never what you want, I think steering angles should be set (by the player) so the wheels form an arc, so steering direction for interior steerable suspensions "should" be chosen to intersect as close to the intersection of the front and rear steering normals if that's clear.

Sry, been busy and forgot to reply. I think this is the issue and the reason it seemed to be random was because some of the items I loaded up weighed more than others and the center of mass was different in some cases. I will reconfigure my hot ars so I can toggle steering inversion as needed for now until it gets fixed

Hello Steven,

Thank you for confirming.

As mentioned earlier, we already have an internal ticket for this issue and it’s still being investigated on our side.

For now, we’ll merge this thread with the previously reported one, and we kindly ask you to keep an eye on that thread for any future updates or fixes.

Thank you for your understanding.

Kind Regards,
