ShareTextures vs Sketchfab

ShareTextures is a web library of free textures, 3D models, atlases, and other digital assets. Its About page lists more than 1,600 textures, 250 3D models, and 50 atlases. Visitors can download selected assets without registration or payment, at resolutions up to 4K. The Free asset library costs nothing, and listed formats include BLEND and FBX. ShareTextures describes downloads as CC0, while its license page specifies a custom CC0 license: personal and commercial use is allowed without attribution, but redistribution on other websites and embedding downloads in third-party apps require written permission. A Blender add-on supports browsing, previews, drag-and-drop placement, 1K–4K resolution choices, automatic shader nodes, catalogs, and tags. Access is offered through Patreon or a one-time purchase, with lifetime access and free updates for the one-time option. An Unreal Engine plugin creates physically based materials with one-click import and automatic material graph setup, with 1K, 2K, and 4K options through the Epic Games/FAB Marketplace.

Sketchfab is a platform for publishing and finding 3D content through an interactive viewer. The viewer can be embedded on websites, allowing 3D and VR viewing without leaving the host site. Its built-in editor adjusts orientation, materials, lighting, camera parameters, and post-processing filters. Upload formats include OBJ, FBX, Blender, STL, and glTF, and exporter plugins are available for Blender, Maya, SketchUp, Unity, and ZBrush. APIs support model uploads, data access, downloads, and viewer control or embedding. The Download API provides glTF, GLB, and USDZ, not source formats such as FBX and OBJ; owners control whether their models are downloadable. Basic is free and allows model files up to 50MB. Pro costs $15 a month billed yearly, with a 200MB model limit and private uploads. Premium costs $79 a month billed yearly, with a 500MB limit and advanced embed customization. Enterprise pricing is by quote.
