Hmmm, Strangely I don't think i've made a single axle template. It's definitely possible, just no template exists yet. I'll see about getting one in for the next release. When you say a "regular single axle trailer" do you mean like a passenger vehicle box trailer?

@@GDCorner Yes, that's exactly what I was thinking - a regular single axle box trailer, typically used for passenger vehicles. Thank you for considering adding a template for it in the next release!

If it's already setup as a chaos vehicle you should be able to just skip to the training section and train it. If it's not appearing in any drop-downs, can you please email a few screenshots of the vehicle blueprint to support@gdcorner.com?

@@GDCorner I can do you one better on that one. In this case I'm using the AUDI from the Vehicle Configurator project. Would you like to look at that, or would you rather me just send you the screens?

@@MADMOVIESINC Heya, that vehicle needs to be converted to a Chaos Vehicle. You can follow a guide such as Marcos in the link below. If you are still having issues please email me at support@gdcorner.com th-cam.com/video/GcsVkmlpVTw/w-d-xo.html

Sorry, I'm not sure I understand? What do you mean by ground detection? Chaos vehicles have gravity and collision detection integrated. Are you able to send a screenshot or video of what you mean to support@gdcorner.com?

The importer will merge meshes and allow you to utilize nanite and so on allowing for efficient assets if that's what you mean. As for the AI, it's good for cutscenes and cinematics but I wouldn't consider it a Game AI as it doesn't have features like collision avoidance and rubber banding/catch-up that you'd want in a game AI.

Heya, my guess would be that your blender add-on and your unreal plugin are different versions. There was a format change in the export. In the latest versions. What version of rush hour are you using in unreal? You can try version 1.4.2 of the blender add-on which might fix it. But feel free to send the exported json and your unreal log from <project dir>/saved/logs to support@gdcorner.com and I'll have a closer look

Heya, sounds like either the ground collision, or the vehicles physics asset isn't right. To check the physics asset see 8:53 in this video. If the wheel bodies in the physics asset look good then checkout the Player Collision visibility mode by clicking the Lit menu in the top left of the viewport and clicking Player Collision. This should allow you to visualise the collision of the scene. If it's still not working please email me at support@gdcorner.com and we'll get to the bottom of it.

Hey, yes it does. The latest versions of the plugins should list what version they are tested with on the download page. If you are still having issues please send any error messages through to support@gdcorner.com

Hi, to make the car faster will be a matter of tuning the Vehicle Movement Component. You'll probably need to change the gear ratios and the max torque. For more information look up Chaos Vehicle tweaking guides

Heya, thanks for reaching out. So what's happening? Is the vehicle going off the path? Which vehicle are you using and what driving profile are you using?

@@GDCorner all I see is a Forrest. There is no road on the project file

Hmm. It was definitely in the version I downloaded in June 2023 from the Marketplace. You might have to reach out to MAWI to see if it's been updated since.

Heya, Bikes, or 2 wheel vehicles in general are untested at this stage. Rush Hour sends driving inputs to Chaos Vehicles, but 2 wheeled vehicles have a balance factor that Rush Hour doesn't take into account.

Hey, bikes aren't supported by the importer, and are untested for any custom chaos vehicles. There's a balance element for bikes that rush hour doesn't factor in. As for detailed suspension, chaos vehicles handles the suspension movement, but if you are referring to the visual elements of things like springs and things compressing, this is a per vehicle setup and isn't factored into the importer. It requires custom work in the animation blueprint and probably custom rigging too.

Hey, sorry for the long response. My suggestion for this is generally to adjust your path, get the vehicle movement right, then record with take recorder. After it's in sequencer you can then attach your character via sequencer using normal sequencer animation tools. Hope that helps.

Thanks for the feedback. It helps prioritise new features. At this stage blender is the supported toolkit as it's available to everyone, where as max, maya, c4d etc are only a subset. In the future with enough demand there may be additional addons created for other software.

Heya! I just setup a new project with that vehicle to check. There's a small bit of logic in the MZDRX7 blueprint that overrides the input controls. You need to bypass one node. Open BP_MRX_RACER, Open Event Tick. You can See Event Tick -> Sequence -> Then 0 -> Vehicle Inputs -> Camera Input. You need to drag from Then 0 straight to Camera input and bypass Vehicle Inputs and it will work. Hope this helps!

@@GDCorner It worked thank you

Hey I have a question. I just got my degree on Software Development and security but I'm loving Unreal Engine and want to dive into C++ do you recommend any courses or training to dive into thanks

@@rtz2985 Hey, great to hear your are looking for a deeper dive. I can't personally recommend any as I've been working with it for a while and just learn as I go these days. I've heard great things about Tom Loomans Unreal C++ course, but if you are looking for a wider/more generic c++ course I'm not too sure.

@@GDCorner Thank you for the recommendation. One last question, I posted it on the questions tab on the product so an answer either here or there would be great. I have two poliece cars and I'm trying to do a police chase but the sirens won't animate with the trigger. They do work under the regular playgame but not during the rush hour animation. Anything I can do to make it work? Thank you

Sorry you've had a bad experience. The AI driver should be quite accurate, as long as you've trained the vehicle. If you are having troubles feel free to reach out via support@gdcorner.com, or my discord. The nature of simulation does mean that you do need to do a bit of trial and error. This method is especially useful for physics interactions with other physics bodies which the control rig method can't respond the same way. Things like trailers and collisions. It also produces natural bodyroll without needing to keyframe every bit of body movement.

@@GDCorner ok let c how accurate it can b

These should usually go on the body.

Yeah, once I started playing with it I couldn't resist adding that trigger and impulse!

Heya, sounds like maybe there was something missed in the physics asset. Can you send a screenshot of it to support@gdcorner.com?

solved it - I had to apply all transforms to get rid of some negatives scales!

Heya, that's typically seen if you are using blender 4.0 which isn't supported at the moment. please try with Blender 3.6. if you keep getting the error please send me the error to support@gdcorner.com

@@GDCorner yes I went down to blender 3.5 and I sent u the email with the photo of the materials. Thank u. I need this to work so bad. This is an amazing plug in. Thank u for this contribution to the community.

No probs. We'll get ya going. Haven't received an email yet, will keep an eye out for it.

Heya, just following up. Still haven't got an email. Can you verify what email you sent it to or check for a rejection email?

@@GDCorner sent just now

Hi, you can make a closed loop by selecting the Rush Hour Path in your scene outliner, then in the details panel search for "Closed Loop" under "Spline" and enable that.

@@GDCorner Yes did that but the car stops at the last point created in the spline even the spline is a closed spline.

Hmmm. Did you also change the last waypoint action to "continue"?

Hi, unfortunately full on drifting isn't supported as that is very dependent on exact car physics configuration. I demonstrate how to do car powerslides in the feature walkthrough video for 1.4 though.

Hey thanks for the feedback. Interesting point. I believe rush hour is capable of these more basic and slow movements, but I don't really show them in videos as they aren't exciting. It's a great point though that needs to be demonstrated. I'll make sure to include some more basic driving maneuvers in the next video.

Heya. Yeah, downloading models can be hit or miss finding one that is ready to go. Often you need to do a bit of clean up. You can split the meshes in Blender which doesn't take too long and will make it much easier to work with some downloaded models. These videos shows how to split by loose parts or material, and you can also select parts of the mesh and split by selection. th-cam.com/video/GhaIzn8ts14/w-d-xo.html th-cam.com/video/ePEqn1mz8Ec/w-d-xo.html

@@GDCorner thank you for this!

Hi, Unfortunately scaling chaos vehicles isn't the easiest thing to do. The easiest approach is probably just to rescale in blender and re-import. If this is a vehicle that wasn't imported with the importer, I think you'll need to resize the Skeletal Mesh asset, and then each individual static mesh if you have them. You probably can't just do this within the Blueprint.

Hello, apologies, i missed this message. Looks like you are using Blender 3.1. The currently supported versions are 3.3 and 3.6. I mainly target the current Long Term Support releases.

Yep, the name is very important! Thanks for the feedback. I'll take not of it when I update the tutorial next.

Heya, yeah occasionally Unreal creates physics bodies for the brake calipers which causes this. Sometimes it happens on some wheels but not others. Either way, the fix is pretty quick, you just need to delete those physics bodies. More details here: www.gdcorner.com/documentation/rushhour/80-troubleshooting-vehicle-importer.html#the-brake-calipers-are-poking-through-the-wheels-and-rotating Hope that helps!

Heya! The Blender addon doesn't yet support Blender 4.0. Please try again with Blender 3.6.

@@GDCorner thank you sir

Heya. The blender addon will create a new hierarchy that almost matches the collections in the blender scene, but not quite. If you need a more specific hierarchy then you can either: A) export/import as normal with the rush hour workflow, and then selectively replace assets with your own, B) Create and setup a regular chaos vehicle. Hope that helps!

Thank you!!@@GDCorner

Nope. Align to ground should be there. Are you using the beta or the one on the store? I believe it may have moved up or down a bit in the beta. Please reach out on support@gdcorner.com if you are still having issues. It's a bit easier for sharing screenshots

I just placed it all by hand. Didn't take too long. Just placed larger fires in the background and smaller fire systems closer to the road to create a layered effect. Alt+left click and then dragging the move gizmo should duplicate it which makes it really quick to work through.

@@GDCorner wow man, I’m shocked. For me it was so time consuming due to high differences in terrain and snap to flor tool do not work for particles.

Heya. The prep tool and importer only handles driving etc. Destruction and deformation has to be manually setup and configured.

Thank you! Noted on the driver. I'm not much of a character animator, but will see for the future.

Heya, Yes, you would use Take Recorder for recording to a sequence.

You can record the vehicles to sequencer which will give you key frames you can adjust, but it won't be as easy as control rig. I have a control rig method under development that I'll be releasing at a future date. Stay tuned!

@@GDCorner Thats great to hear thank you,. If I want to use a diffrent drivable bleuprint vehicle, does it need to trained first or can it just be replaced?

Yeah vehicles need to go through the training process so the AI gets tuned for the particular handling of that vehicle. Training will also need to be re-run if you significantly alter the vehicles physical properties.

🙏🙏 Thanks @@GDCorner
