3DTextures.me vs ambientCG

3DTextures.me is a web library of free seamless PBR and stylized textures for digital art projects. Texture posts can include Diffuse, Normal, Metallic, Displacement, Roughness, and Ambient Occlusion maps, with downloads in PNG and SBS/SBSAR formats. The site says the textures work with Unity, Unreal, Godot, Blender, Maya, and 3DSMax. They are licensed CC0, allowing commercial use without attribution; redistribution is allowed, but users may not claim authorship. The Free textures plan costs nothing and requires one-by-one downloads. Supporters can receive a link for downloading all textures, while support of 3 or more coffees includes a 4K textures folder and other textures. A supporter-only interactive library provides previews and filters by name and date added. The site also offers Align Tools for Blender, and its FAQ directs questions to a contact form.

ambientCG is a free library of downloadable assets for 3D art, architectural visualization, game development, VFX, and related work. Its collection includes PBR materials, HDRIs, Substance graphs, atlases, decals, photo textures, models, and terrain; the homepage lists 2,895 assets. Downloads are available in JPG and PNG. The assets use the Creative Commons CC0 1.0 Universal license, permitting copying, changes, distribution, and commercial use without permission, and attribution is not required. You can browse and download on the website or use the API to search and download assets with code; its documentation lists v1, v2, and v3 endpoints. The creator cautions that the API may not be stable or reliable enough for enterprise applications. Documentation also covers use with Blender's Asset Browser. Patreon supporters may receive early access and easier batch downloads, and the homepage mentions ad-free browsing. Access to downloadable assets is free at free.
