PBR-Midgard Expedition Vehicle 3D Model

I am proud to present the "Midgard Explorer" — a 3D model of an extraterrestrial exploration vehicle designed for brave explorers. The name is inspired by Midgard, the realm of humans in Norse mythology, symbolizing a bridge between Earth and distant planets. This 3D model embodies the aspiration to explore the unknown and connect our world with the far reaches of space.

Design Philosophy:

From the outset, I aimed to create a 3D model of an extraterrestrial exploration vehicle with robust survival capabilities. The "Midgard Explorer" is designed to meet various needs in extreme environments, ensuring superior off-road performance, life support systems, and self-sustaining energy solutions. Here are some key design features:

Superior Off-Road Capability: Equipped with a 6-wheel independent double wishbone suspension system and all-terrain tires, the "Midgard Explorer" can easily navigate through complex terrains, from rugged mountains to soft sand dunes.

Efficient Life Support System: The vehicle is designed with an oxygen conversion unit and plant cultivation chambers (the 3D model does not include plants; users can add them as needed), ensuring a comfortable, safe, and sustainable living environment for the crew.

Green Energy Solution: Fitted with solar panels and efficient energy storage units, the vehicle achieves self-sufficiency in energy, reducing dependence on external supplies.

Advanced Scientific Equipment: The vehicle is equipped with a range of advanced scientific instruments and devices, including ground-penetrating radar, life detectors, and high-definition cameras, to support comprehensive scientific missions.

Comprehensive Basic Living Facilities: In addition to its research functions, the "Midgard Explorer" includes essential living facilities such as a restroom, bunk beds, and food processing areas, ensuring that the crew can enjoy basic comforts during long-term missions.

Technical Details:

Texturing: The "Midgard Explorer" 3D model was modeled and UV-unwrapped using Blender 3.21, with material textures created in Substance Painter. To address issues with UDIM UV mapping, which caused texture embedding problems in FBX files and inconvenience for users, I used a traditional UV unwrapping method. The UVs are divided into parts such as the suspension, body shell, external equipment, and interior facilities. Most major parts have 8K textures, while smaller parts have 4K textures. Two sets of textures, clean and dirty, are provided and embedded into the FBX file for easy use in other 3D software.

Skeleton Rigging: The Blender file of the "Midgard Explorer" 3D model uses Blender's physics constraint system for rigging. A single controller is used to control the vehicle's movement, and the ground is given a "passive rigid body" physics constraint, allowing the vehicle to interact correctly with the terrain. Pits or "passive rigid body" objects on the ground will automatically provide physical feedback to the vehicle (see the video in the details for specific effects). Multiple doors, seats, and the restroom door can be controlled individually using separate controllers, making it very simple to animate.

For Unreal Engine: I am currently developing a version of the "Midgard Explorer" specifically for Unreal Engine. The vehicle will be rigged with bones and procedural controllers in Unreal Engine, allowing a first-person character to move inside the vehicle. The character can control the vehicle from the driver's seat, similar to a typical racing game, using WSAD keys for movement and the space bar for braking. The vehicle will also feature a full suspension system. Once the Unreal Engine version is complete, it will be added to this product, and there may be a slight price adjustment. However, I can assure you that the additional value will justify the price change.

Included Files:

1.No Rigging "Midgard Explorer" 3D model .blend file

2.Physics Bone Rigged "Midgard Explorer" 3D model .blend file

3.Clean and Dirty "Midgard Explorer" FBX files

4.Texture package, including two sets of textures for clean and dirty versions

Notes:

1. Rendering may encounter out-of-memory errors. Solution: Since all textures are packed into the .blend file, unpack the external data to a local folder on your computer (Method: File - External Data - Unpack All).

2. The model was created in Blender, and the textures were made in Substance Painter.

3. When making animation, you only need to add key frames on the controller, and the vehicle will move according to the animation of the controller. Remember to understand the calculation results of the baked goods in the "rigid world environment" when rendering, and set the simulation time to the overall animation time.
