What's new in 1.4

• Whole body swap (tab "Body") - another vehicle's whole body on yours, without its wheels, engine and chassis. Its lights work and it takes damage like on its own car. Tick which body parts come along, and hide your own body if you like. (For now it works poorly)

• Saved vehicles (tab "Saved") - save a finished vehicle by name and spawn it again later, on any map.

• Rear wheel steering (4WS), like the Ibishu Pessima ZX AWS (tab "Suspension") - by speed, like the Pessima (by the steering angle), always the opposite way or always the same way (crab walk), up to 45 degrees. Only the wheel with its disc turns, on a kingpin of its own - it works on solid axles too.

• A different wheel on every corner (tab "Suspension") - switch it on and the game's own Parts menu gets "- left" and "- right" next to "Front Wheels" and "Rear Wheels": a rim and tyre of its own for every wheel.

• Part pictures - rest the mouse on a part in the list and a small window shows its 3D model. Picking a vehicle makes the pictures of all its parts by itself, so next time they show at once.

• A cleaner part list - parts that would do nothing on a vehicle (bulbs, ECU tunes) are left out; parts with devices but no model are marked "data only" and say what they add.

• Lights grow with the part - a scaled-up lamp shines brighter, further and with a bigger flare.

• UI size slider (x0.8 - x2) - a bigger size has to be approved within 15 s, otherwise the old one comes back; the window always opens at x1.

• Auto undo - if the vehicle goes unstable within 20 s after a change, the change is undone and the vehicle is put back as it was.

• Suspension swap - the orange main button is now the real geometry swap; "LOGIC" (only the character, your geometry stays) is the button below it.

• Trucks - the T-Series front axle is recognised for a front suspension swap.

• Fixes - lamps that share their nodes (e.g. the pickup's Quad Round Lights) attach properly and roof lights no longer shake the physics; added parts with seats no longer blow the physics up; bulbs and sun visors of added parts sit on the right nodes.




What's new in 1.3.1

• 
  
  
  • 6 new languages: German, Spanish, Italian, Russian, Chinese (Simplified) and Japanese - besides English and Lithuanian. Pick one with the buttons at the bottom of the window ("Language / Kalba"); the choice is saved, and the card in ESC > Mods follows it.
  • Chinese and Japanese use the game's own Chinese / Japanese font, so their letters show properly in the window.

1.3

• Exhausts that work - an attached exhaust now smokes, pops (afterfire) and sounds from its own tips like your car's exhaust. Any number of them - two or three different exhausts at once work too.
• Size per axis (X / Y / Z) - besides one size for the whole part, width, length and height can each get their own factor: a wider bumper that is not taller. Model and physics both.
• Type exact values - every position, rotation and size slider now has a number field next to it.
• Copy - one more of the same part as a new preview, at the very same place, turn and size. Works for a preview (section 2) and for an installed part (section 3).
• Donor liveries - your car's livery only fits your car's own parts, so parts from another car and a front end swap can now wear one of their own car's liveries: "Livery (donor)" in section 2 and section 7, and a "Livery" button by an installed part in section 3.

Multiplayer (BeamMP)
Tested on a BeamMP server: put the zip in the server's Resources/Client folder and set MaxCars to 2 or more (a part preview is a vehicle of its own while you place it). Disable your own local copy of Part Attacher before joining.

Known issues

• Some small light parts (roof lights) can make the physics shake when attached.
• Exhaust effect mods (volumetric smoke / backfire) draw their own smoke and flames, and the volumetric smoke mod uses at most 4 pipe tips per car.

Install / update
Remove the old Part Attacher zip from your mods folder, put the new one in (BeamNG.drive/current/mods), enable it in the Mod Manager and restart the game once. Your saved cars keep their parts.

Bug reports: please attach settings/partAttacher/last_load.log from your BeamNG user folder (and beamng.log).

Part Attacher
Mod author: Kavencki - Giedrius P.

Put any part from any vehicle - official or modded - onto your car. The part becomes a real part of your vehicle's jbeam (not a separate vehicle): it has its own weight, physics and collisions, and it stays after a reset.

Features

• Any part on any vehicle - bumpers, bull bars, rock sliders, roof racks, lights, body kits... Pick the donor model, find the part in a slot tree like the game's Parts menu, place it with sliders and attach.
• Part pictures - rest the mouse on a part in the list and a small window shows its 3D model; picking a vehicle makes the pictures of all its parts by itself. Parts that would do nothing on a vehicle (bulbs, ECU tunes) are left out of the list.
• Virtual mount - a part with physics hangs on 8 frame points that are welded to your car's structure, never on your car's nodes directly, so attaching it can't tear your car apart. A bull bar works as a bull bar.
• Model only - just the model, no physics (decorations, radiators). Switch any installed part between model only and physics with one button.
• Auto position - a new part appears where your car's part of the same kind is. Mirror copy - the same part on the other side. Copy - one more of the same part at the very same place, turn and size.
• Size - make a part smaller or bigger, as a whole or per axis (X / Y / Z): a wider bumper that is not taller. Model and physics both - and a scaled-up lamp shines brighter and further.
• Exact values - every position, rotation and size slider has a number field next to it: type the value you want.
• Engine swap (logic) - any engine's power, torque, revs and sound on your engine's physics, so nothing breaks. The donor's tuning parts (ECU, internals, turbo, N2O) appear in the normal Parts menu.
• Gearbox swap - manual, automatic, DCT, CVT, sequential from any vehicle.
• Turbo / supercharger from any vehicle onto your engine - with sounds, settings in the Tuning menu.
• Radiator - any vehicle's cooling onto your engine. Snorkel - an attached snorkel really works: the engine takes its air through it.
• Exhausts that work - an attached exhaust smokes, pops (afterfire) and sounds from its tips like your car's own, for any number of them (two or three different exhausts at once too).
• Donor liveries - parts from another car, a front end and a body swap can wear one of their own car's liveries (your car's livery only fits your car's own parts).
• Suspension swap - a full geometry swap on its own virtual frame (the main button), or logic mode (donor spring / damper / sway bar character + ride height and stiffness sliders). Truck front axles (T-Series) too.
• Rear wheel steering (4WS) - like the Ibishu Pessima ZX AWS: by speed, by the steering angle, always opposite or crab walk, up to 45 degrees. Each rear wheel turns on a kingpin of its own, solid axles too.
• A different wheel on every corner - the game's own Parts menu gets "- left" and "- right" wheel slots: a rim and tyre of its own for every wheel.
• Second rear axle - add a second rear axle behind your own (6 wheels, 6x4 truck style); both rear axles are driven.
• Universal drivetrain - RWD / FWD / AWD with any gearbox, open / LSD / viscous / locked diffs, lockable front, rear and center diffs, switchable 2WD / 4WD, low range - all switched while driving.
• Safety electronics on any vehicle - ABS, traction control, stability control, 2-step launch control, line lock.
• Front end and whole body swap - another vehicle's whole front (bumper, fenders, hood, headlights, grille) or its whole body (without its wheels, engine and chassis) on yours, fitted to your car, bending and breaking like on its own car, lights working. Your own parts come off and come back when you remove it.
• Hitches that work - an attached fifth wheel, pintle hitch or tow hitch couples trailers like on its own vehicle; the fifth wheel plate still tilts and slides.
• Data-only parts - a truck's air compressor and similar parts go straight onto the car and connect to your engine.
• Saved vehicles - save a finished vehicle by name and spawn it again later. Everything is also saved with the game's own vehicle save and loads on any map.
• Multiplayer (BeamMP) - put the zip in the server's Resources/Client folder and set MaxCars to 2 or more; other players see your previews and your finished car.
• Crash protection while new parts settle, auto undo if a change makes the car unstable, a diagnostics log for bug reports, 8 languages (English, Lithuanian, German, Spanish, Italian, Russian, Chinese, Japanese) and a UI size slider.

How to use

1. Get into your vehicle and press Ctrl + Shift + Y (rebind in Options > Controls > Gameplay), or press ESC > Mods > Part Attacher > OPEN PART ATTACHER.
2. Part tab: pick the donor model and a part (or a swap folder at the top) and spawn the preview; move / rotate / resize it right there and press ATTACH.
3. Installed tab: move, remove, mirror, copy, change the livery of or switch what you added.
4. Drivetrain, Suspension and Electronics tabs: universal drivetrain, logic suspension, safety electronics.
5. Front end tab: pick a donor vehicle and press SPAWN FRONT END.

Full manual: README_EN.txt in the mod zip.


What's new in 1.2

• Front end swap (new Front end tab): the whole front of another vehicle in one go, auto-fitted to your car's front and width, with damage like on the donor.
• Multiplayer (BeamMP): other players' games now spawn your part previews correctly (they stayed lying on the ground before).

What's new in 1.1

• New window with tabs in the BeamNG style; the position of a new preview is on the same tab as the part list.
• Fifth wheels, pintle hitches and tow hitches from other vehicles work (trailers couple).
• Parts far from the body can hang on a swapped suspension's frame or on parts added before (a fifth wheel on a swapped semi axle).
• Air compressor and other data-only parts install directly and connect to the engine.
• Fixes: rubbery damage after swaps, brake discs moving on rotated suspension swaps, semi truck rear suspension exploding, Model list shows only drivable vehicles (trailers and props in folders).

Install
Put the zip in your mods folder (Documents or AppData: BeamNG.drive/current/mods) and enable it in the Mod Manager. Restart the game once.

Beta notes
Suspension geometry swaps between very different vehicles can still be unstable - use the suspension LOGIC mode for those. Some small light parts (roof lights) can make the physics shake when attached. Exhaust effect mods (volumetric smoke / backfire) draw their own smoke and flames; the volumetric smoke mod uses at most 4 pipe tips per car. If something explodes or hangs loose, please attach settings/partAttacher/last_load.log (in your BeamNG user folder) to your report.

Made for BeamNG.drive 0.40. Free.
