Hi! I prepared game-ready modular asset pack to build as many variants of wooden carts as you need. I designed it with Unreal Engine in mind, but it'll work in Unity as well (or any other game engine).

It contains 43 basic pieces all sharing one UV space to build countless variations of wooden carts: 6 types of wood planks 5 types of wood logs 2 types of wood blocks 7 parts for bulding chassis 6 parts for building wheels + 2 full wheels 3 types of front parts 14 metal parts

5 types of already assigned meshes (it's one objects per mesh to keep things clean, so if you want to modify them you need to do this inside some kind of 3D software, all other things you can do in Unreal Engine) Smallest - 6k tris Small - 4,2k tris Medium - 12k tris Large - 12k tris Carriage - 15k tris

Modelling was done in Blender, texturing in Substance Painter.

Textures: Three sets of 4K textures (Normal maps (OpenGL) + Diffuse + roughness + metallic + AO) to use anywhere + packed UE textures as the unreal assets.

Materials: Only for Unreal Engine, 3 PBR materials with different texture sets all ready to go.

You can check how it's looking in Unreal Engine among preview images.

Blend file contains high-poly, low-poly and baking meshes.

You can check UV among the preview images.

Hope you like it! :) If there is anything wrong or not working tell me about it, and I will do everything to fix it as soon as possible.
