unfortunately there is no plan to add client authoritative replication right now.
you could disable the replication component and try unreal’s own replication or you could modify the existing replication component. use projective velocity blending algorithm if you can(implemented in current replication component), here is a video about it :
Hey, thanks so much for getting back to me. I appreciate the advice and we’ll look at our options, cheers!
HI,
thank you for your plugin and amazing support. I’m trying to implement the feature, where the car ( Basis_BP) has a collision box as an additional component in front of the car at the distance depending on the speed of the car. I need this feature to signal another car to slow down if there’s a car coming from left or right side. So the problem is I can’t figure out how to set up the collision box so it will not collide with the car but will respond only to visibility channel. It seems like the tires ignore the setup, because I managed to set up to ignore collision of the car body but the tires are still collide with the collision box. Is there something I missed? I hope you understand what the issue I have here.
thank you!
an additional collider for collision queries? you are probably messing with the vehicles inertia that way, not to mention the other problems that can arise. why don’t you make sweep queries, we used such queries to detect incoming collisions in our game.
I will explain in a different way, if I may. No I’m not messing with inertia, the car blueprint is intact. Let’s say the car is approaching the crossroad, another car is approaching the same crossroad from the left side. When I use the line trace for detecting car in front it will be to late to slow down when one of the car is already at the crossroad and they will collide with each other, so I’m using the collision box which is in front of each car at some distance so another car could detect the car way before the collision and have time to slow down and get another car to pass. I wish I could attach the picture, can’t figure out how. I’m sorry for clumsy explanation…
A bit about the collision box, custom preset, query only( no physics collisions), trace responce - block visibility only, object responces - all ignore.
My understanding is if collision box have no physics collision set up tires should ignore the collision? But they are coliding 
i see, so your problem is that wheels still hit your query collider.
the default query trace channel for vehicles is “visibility” so you either use a different(custom) trace channel and update your world accordingly or set the other collider to avoid queries for visibility channel.
i didn’t try what you want to do exactly but even if you change query mobility type to static then the wheels shouldn’t hit your query collider.
Yes, I set up another trace channel and it did the trick!
Thank you!
This might be stupid but is this also the case with manual transmission ?
Cause while testing it was possible to let the car roll backward from a hill and accelerate and get the rear tire to spin correctly, so I assume that this is an intended treshold to limit tire spins, I would like to be able to modify it though.
Looking forward to buy that plugin and this is something I’m likely to mess with, though ultimately it wouldn’t be a deal breaker. I’m thinking if there is a way to maybe force reverse then 1st gear through blueprint and make my own treshold then re-enable automatic transmission once the first gear was forced to be seat… If this is possible then this is likely easily fixable by myself without modifying the source code 
i couldn’t exactly understand what you meant in the first paragraph but you can switch to manual transmission and make any gear changes and then switch back to auto transmission from blueprint.
While I am thinking of getting this plugin, I’ve been experiencing major issue with Epic’s vehicle and my terrain:
It drives fine on the face of the static mesh terrain, but as soon as it goes over the edge between adjacent triangles, it drives over an invisible surfaces and then “falls off” it, and flips violently.
I already used “pxvis collision 1” cmd to see if there is anything there and there was nothing. I tried complex collisions on the terrain mesh, I tried simple collisions (each triangle was represented with UCX hull) - same exact result with flipping vehicle.
That being said, I would not like to spend money on the plugin just to find it has same exact issues as stock Epic’s vehicle.
Do you happen to know what’s going on there and if something like that can manifest with FGear too ?
some people have encountered weird collision issues before but they were all meshes, we have a landscape in our game and we have never experienced any problems. that being said, i can’t say for sure that it won’t happen with fgear, if there is a collision glitch then it can possibly cause issues.
Well perfect then ! I was mentioning one of your old answer so it might have had been hard to understand what I was referring to. I was talking about being in reverse and pressing the throttle input, and it braking until arriving at a dead stop then putting in 1st gear, which is an expected behavior as it limits tire spin, but I was thinking of actually having intentionally tire spinning in that scenario. Hope it cleared it out a bit, thanks for your answer too.
EDIT: thinking about it, it makes sense too, best thing would probably be to let the car rev in neutral for a bit to build torque to get tire spin, otherwise it’ll just try to stall I guess, so it’s preferable anyway to custom make it to fine tune it how I want. Again thanks for your answer, gives confidence for me to purchase your plugin
There is another thing I was wondering though, I’ve seen in the doc there is an oversteer assist, and I was wondering how was that working. Does it automatically steer ? And if so, is it adjustable at which amount it does it ?
over/under steer assist is like esp, uses brakes to overcome instability, they don’t work very well though. there is also a steering assist, it automatically steers towards vehicles travel direction. all these assists have a range value between 0…1 so that you can adjust their amount.
Perfect ! Again thanks for your answer, I appreciate it.

I’m getting this crash?
it looks like your steer limit curve is null, did you provide it?
we check if it is null and create a default one normally but somehow yours seem to be deleted. does it happen immediately or after some time?
hi @anonymous_user_8b3c65dc did you solved your problem?
Yes, partially, it is a bit complicated, I’ve managed to migrate fgear to the project. Basically, you need to copy fgear sample folder to new folder, check if it works. Then you need to rename this project so it will have the same name as your target project (the blueprint project where you need to add fgear cars). For renaming I used the tool called . After renaming put .sln file Source folder and Content folder into your target blueprint folder. Add fgear plugin description in the .uproject file or activate it in the editor.
As a result I’ve got it work in the editor (fgear sample maps work in the editor) but after packaging (successful) the project is not launching, i.e. when I click on exe file it does something but the game is not loading. I don’t know what the problem, trying to figure it out. Maybe lazybitgames could help? I suspect it could be something in my blueprint is messed, but it works fine without plugin, when I delete previously migrated fgear files and folders. I would like to take a look at logs but I can’t find where are they?
Any help or suggestions appreciated.
Thanks!
Update:
Yep, after deleting the files and folders related to fgear the project works as it should. The blueprint project I’m working on is quite big and it seems that fgear is messing in some way. What be your suggestions regarding diagnostics/checks I can do? I would be very happy to implement fgear in the game and so far I’m stuck with the issue and feel a bit frustrated!
Hi @anonymous_user_8b3c65dc
I have tested today. I listed my steps here:
1-Install fgear plugin from epic launcher
2-Create a blueprint project with same version of the fgear plugin
3-Open your blueprint project and enable fgear plugin in plugin window
4-Restart editor
5-Copy “FGearAssets” folder to under content folder of the project
6-Open any example map in FGearAssets/Maps/ and play it.
Pls send me your log file after crash editor. Your Project\Saved\Crashes and Project\Saved\Logs. Also check your project version and fgear plugin version same or not.
