Video Demo Doc ReplaceDriver

This template features a physic constraints based All Terrain Vehicle (ATV) made with static meshes and animated using timers inside the pawn Blueprint.

  • Track can be created automatically following a landscape spline or can be adjusted using a spline to be dragged along the path, Pit box lanes can be easily added to allow refueling
  • Starting gate Blueprint will monitor each pawn lap time and uses a 3d widget to display infos
  • The atv is fully customizable and meshes can be replaced with different ones just by changing the components inside the Blueprint
  • Racing AI not based on navmesh with a basic avoidance system and auto refill system when the fuel is lower than a value
  • The driver is not animated but it's simulating physics and a ragdoll system that can be triggered when needed
  • Easy to migrate
  • AI can be enabled or disabled when needed like a car auto-pilot
  • The front suspensions of the ATV simulates a simple double wish bone suspension with realistic results and the vehicle collision with environment is highly reliable.
  • Forces can be adjusted to provide a fully customizable driving experience based on your needs
  • Automatic refueling system using a fuel pump Blueprint and a pitlane track based on splines


Technical Details

Features:

  • BP_ATV pawn class that contains all the vehicle logic like rpm, brakes, sounds and the ai system
  • BP_Track actor class that contains all the system to create a track that can be used by the ai
  • BP_StartingGate actor class that is used as trigger box but also as 3D panel with best laps etc
  • BP_FuelPump that is used to auto refill the ATV when out of fuel and also to create a pit lane that can be used by the AI system
  • BP_Barrier actor class that is used to create road barriers with hierarchically instanced static meshes and splines
  • BP_Ragdoll that is the actor used for ragdoll

Number Of Static Meshes: 34 total from the ATV body that is 87k Triangles with 4 lods, wheels that are 16k triangles each one with 3 lods

Number of Blueprints: 8

Input: Gamepad, Keyboard, Mouse

Network Replicated: No

Supported Development Platforms: Win 64

Supported Target Build Platforms: Win 64

Important/Additional Notes:

  • The ATV is using Materials from the Automotive Materials because they work well with parts of the body. It also uses a 4k Texture for parts like the brake discs that otherwise will use too many tris and for the decals or other details on the ATV.
  • The ATV model included is using a high poly mesh with more than 100k polygons total that is reduced to 30% of the total with LODs but they can be heavy on certain machines.
  • The transmission chain is not animated (check doc). The vehicle doesn't have a rear differential by design (check doc).
