Detailed Express steam train with baked wheel/linkage animation, PBR textures and URP, HDRP and Built-in prefab/demo setups. Tested in Unity 6.3 LTS.Tested in Unity 6.3 LTS (6000.3.25f1), Linear. URP 17.3.0 default; optional HDRP 17.3.0 and Built-in overrides in Assets/SteamTrain/RenderPipelinePackages. Accept dependency prompts and import the override matching your active pipeline. Overrides replace materials/demo; see README for setup. Open TrainDemo and press Play for the stationary wheel cycle.Build close-up railway scenes with the Express v003 steam locomotive and tender. This edition retains the Grand Canyon / No. 29 markings shown in the owner's gallery. It includes a Unity prefab, animated source FBX, external texture maps and three pipeline-specific PBR model materials.The demonstration scene provides a speed slider for the baked wheel and linkage cycle. The model remains stationary. Rails, track following, smoke, audio and train-physics gameplay are not included.This is a high-detail model with 472,554 triangles across 20 meshes. No LODs are included. The locomotive body and tender are fused in the main mesh; the tender is not independently detachable.URP is the default setup. Optional HDRP and Built-in material/demo overrides are included in Assets/SteamTrain/RenderPipelinePackages. Import the override for your project's active pipeline; it replaces the shared materials and demonstration scene. Follow the included setup documentation and use Linear color space. Each demo uses pipeline-specific lighting and exposure.Gallery images are the owner's Blender renders of Express v003. The Unity edition uses URP Lit, HDRP Lit or Built-in Standard materials according to the chosen setup; Blender lighting and displacement graphs are not reproduced exactly. The final Subdivision Surface modifier is disabled in the non-native export.Tested with Unity 6.3 LTS (6000.3.25f1), URP 17.3.0, HDRP 17.3.0 and the Built-in Render Pipeline. Clean imports, actual GPU rendering, wheel playback, pause and 2x resume were verified for the pipeline variants. The established URP Windows 64-bit standalone build was also verified; new HDRP/Built-in standalone builds and performance benchmarks are not claimed. Original Blender files are not included in this Unity edition.AI assistance was used for Unity integration, demonstration scripting, pipeline conversion and validation tooling. Meshes, source texture maps and gallery renders come from the supplied asset. No AI-generated marketing images were added.20 meshes; 472,554 triangles; 386,696 imported Unity vertices. Individual meshes: 100–395,875 triangles.One zeroed-root prefab, approximately 19.618 m long × 4.760 m high × 3.475 m wide.Rigging: 20 bones. One baked Legacy loop, 1.25 seconds at 24 fps. Four driving wheels and 18 changing transforms verified; no unresolved animation paths.UV mapping included. No LODs, retopology or detachable tender.Three PBR model materials per pipeline, plus demo ground material. Default URP Lit materials; optional HDRP Lit and Built-in Standard overrides replace the same material/scene GUIDs.15 external PNG maps in the base: 12 source maps and three packed metallic/smoothness maps. The HDRP override adds three packed mask maps. Body/smaller-object maps are 2048 × 2048; valve maps are 512 × 512. Base color is sRGB; normals use the Normal Map importer and packed data maps are linear. URP/Built-in packed maps use red=metallic and alpha=smoothness. HDRP masks preserve these channels, with green=1 for unoccluded and blue=1 for the detail mask.Height maps supplied for manual setup; not applied by the demo shader. Final subdivision disabled in the FBX copy: 473,584 → 472,554 triangles. Original native source is preserved.Animated FBX, prefab, PBR materials, URP settings, optional pipeline override packages, neutral demo environment, demonstration scenes, animation controls and Markdown instructions included.Tested with Unity 6000.3.25f1, URP/HDRP 17.3.0 and Built-in, in Linear color space on Windows. URP Windows standalone build verified; HDRP/Built-in verification uses clean-import GPU Editor rendering and actual Play mode.AI-assisted Unity integration, demo C# scripting, pipeline conversion and validation tooling. Meshes and source texture maps come from the supplied Blender asset. No AI-generated marketing images were added.
