PBR realistic 3D model of a fluorescent lightbulb, suitable for renders, games and architectural visualization.

Characteristics:

• Generic, not intended to look like any specific real world brand (copyright safe).
• Fully customizable glass color in Unreal, Blender and MilkShape.
• Compatible with subdivision (mesh smoothing) without changing its original format.
• Base and glass use separated materials.
• Entirely UV-mapped, with fully unwrapped UVs (non-overlapping UVs).
• Objects and materials are descriptively and uniquely named.
• Originally created with Maya LT, textured with Substance Painter.

Included formats:

• Unreal Engine (uasset), compatible with versions from 4.24 and newer, including 5.
• Blender 3.3.1.
• MilkShape 1.8.4.
• Marmoset Toolbag 3.07 Scene Bundle.
• Fbx, obj and dae (Collada) - Require adding the textures manually after you import them in your 3D editor.

Unreal Engine format specifics:

• Demo map included.
• Included one example blueprint (single-player) that suggests how to dynamically change the model characteristics (emissivity and glass color).
• Included material instances allow you to change the emissivity and colors by adjusting simple parameters.
• No third-party plugins needed.

Geometry:

• Sealed geometry (no open edges).
• No ngons (tris and quads only).
• No vertex is connected to more than 6 edges.
• Compatible with subdivision (mesh smoothing) without changing its original format.
• Total poly count is 3932 polys (3930 quads and 2 tris) and 3927 vertices.
• Unreal format (uasset) supports triangles only.

Materials and textures:

• Two materials: MatLightBulb and MatGlass.
• All textures are png, 4096 x 4096 pixels (4K textures).
• Blender, Marmoset and MilkShape formats use relative texture paths.
• PBR textures set: color (no alpha channel), directx normal map, openGL normal map, height, metalness, ambient occlusion, roughness and ORM (composite ambient occlusion (R) + roughness (G) + metalness (B)).
• Unreal format uses 3 PBR textures: color (no alpha channel), directx normal map and ORM.
• Blender format uses 5 PBR textures: color (no alpha channel), openGL normal map, ambient occlusion, metalness and roughness.
• Marmoset format uses 3 PBR textures: color (no alpha channel), openGL normal map and ORM.
• MilkShape format uses the color PBR texture only.
• Exchange formats (obj, fbx, dae): no embeded textures, so you can import them from the PBR set, in accordance to the requirements of the 3D editor you use.

Preview images:

• Preview images depict the actual model, no retouching.
• Preview Blender images are rendered with Cycles.

Units and measurement:

• Real world scale.
• Unit system is metric (centimeters).
• Full model dimensions: 4.2 cm (width) x 15.1 cm (height) x 4.2 cm (deep).

Additional notes:

• Preview images are rendered in Marmoset 3, unless otherwise informed.
• Exchange formats (fbx, obj and dae) were exported by Blender.
