PBR realistic 3D model of a mechanical vintage gramophone.

Characteristics:

• Good for close views.
• Looks believable even when disassembled (hollow pipes).
• Animation ready (hierarchical structure with pivots properly placed, no bones).
• Generic, not intended to depict any specific real world brand (copyright safe).
• All third-party pictures used are either public domain or cc0 (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:

• Blender 3.3.1.
• Unity 2020 (unitypack)
• Marmoset Toolbag 3.07 Scene Bundle.
• Fbx, obj and dae (textures set included separately).
• Unreal Engine 4.24 (uasset), also tested with versions 4.27 and 5.20.

Unreal Engine format specifics:

• Overview map included.
• Included one example blueprint with objects hierarchically placed (no code).
• Included meshes for each part of the model, positioned at the origin, for blueprint use.
• Included one extra mesh with all parts combined, for fully static use.
• Base materials and material instances.
• No third-party plugins needed.

Geometry:

• Model consists of 12 parts: Gramophone, Horn, Arm, Box, Needle, NeedleScrew, Crank, CrankHandler, Turntable, Record, BrakeLever and SpeedLever.
• Sealed geometry / watertight (no open edges).
• No ngons (quads only).
• No coincident (overlapping) vertices.
• No nonmanifold geometry.
• No hard edges.
• No vertex is connected to more than 5 edges (no poles).
• Total poly count is 23765 (23765 quads) and 23817 vertices.
• Compatible with subdivision (mesh smoothing) without changing its original format.
• Unreal format (uasset) triangulates all faces.

Materials and textures:

• One material: MatGramophone.
• All textures are png, 4096 x 4096 pixels (4K textures).
• Blender and Marmoset formats use relative texture paths.
• PBR textures set: base color, 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.
• HDRIs used in Marmoset previews are part of Marmoset software.
• Anthropomorphic mannequin model shown in preview of version 5 of Unreal Engine is part of the engine itself (3rd person template) and is not included.

Units and measurement:

• Real world scale.
• Unit system is metric (centimeters).
• Full model dimensions (horn posed as depicted on preview images): 75.1 cm (width) x 88.3 cm (height) x 56.7 cm (deep).
• Full model dimensions (horn pointing forward): 61.4 cm (width) x 88.3 cm (height) x 57.4 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.
• For your convenience, on Blender format the Subdivision Surface modifier is applied to some parts of the model (you can remove it, if you want).
• Photograph of the painting 'Dog looking at and listening to a phonograph' is now public domain, as its copyright from 1899 was not renewed. Picture and data retrieved from the US Library of Congress, Control Number 96521608.
• Dog barking to music drawing on record labels is public domain and CC0 from RawPixel.
