Naval Mine Low-poly 3D model

PBR realistic 3D model of a naval mine, suitable for renders and games.

Characteristics:

• Good for close views.
• Generic, not intended to depict any specific real world brand (copyright safe).
• Textures are 4K PBR - Physically Based Rendering, for Roughness/Metalness workflow.
• Compatible with subdivision (mesh smoothing) without changing its original format.
• Entirely UV-mapped, with fully unwrapped UVs (non-overlapping UVs).
• Objects and materials are descriptively and uniquely named.
• Originally modeled on Maya LT, textured with Substance Painter.

Included formats:

• Unreal Engine 4.24 (uasset), also tested with versions 4.27 and 5.20.
• Blender 3.3.1.
• Marmoset Toolbag 3.07 Scene Bundle.
• Fbx, obj and dae (textures set included separately).

Unreal Engine format specifics:

• Included one example blueprint (single-player) with objects hierarchically placed.
• The blueprint includes only the model. Explosion logic or effects are not implemented.
• Included meshes for each part of the model, positioned at the origin, for blueprint use.
• Included an extra mesh with all parts combined, for fully static use.
• No third-party plugins needed.

Geometry:

• Model consists of 3 objects: MineBase, Chain and Mine.
• Sealed geometry (no open edges).
• No ngons (quads only).
• No coincident (overlapping) vertices.
• No vertex is connected to more than 5 edges (no poles).
• Total poly count is 20244 (20244 quads) and 20244 vertices.
• Compatible with subdivision (mesh smoothing) without changing its original format.
• Unreal format (uasset) triangulates all faces.

Materials and textures:

• One material: MatMine.
• All textures are png, 4096 x 4096 pixels (4K textures).
• Blender and Marmoset formats use relative texture paths.
• PBR textures set: base color (no alpha channel), both directx and opengl normal maps, height (bump), metalness, AO (ambient occlusion), roughness and ORM (composite ambient occlusion (R) + roughness (G) + metalness (B)).
• Exchange formats (obj, fbx, dae): no embeded textures, so you can import them from the PBR set, in accordance to the requirements of your 3D editor.

Preview images:

• Unreal preview images captured with Auto Exposure disabled.
• Preview Blender images are rendered with Cycles (not tested with Eevee).
• HDRI used in Blender previews is CC0 from Poly Haven (formerly HDRI Haven) and is included.

Units and measurement:

• Real world scale.
• Unit system is metric (centimeters).
• Full model dimensions: 214.6 cm (width) x 710.3 cm (height) x 201.1 cm (deep).

Additional notes:

• Fbx and obj formats were exported by Maya LT.
• Collada (dae) format was exported by Blender.
• The obj format does not preserve the hierarchy or the pivots locations of the different objects. If you import this format, you may need to redo what it lacks.
