3DTextures.me vs CGBookcase

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.

CGBookcase is a free web resource for physically based rendering textures and material guidance. Its catalog lists 566 free textures with filters for 1K, 2K, 4K, 6K, and 8K resolutions. Textures use the CC0 1.0 license, allowing free use without credit, including commercial work. A listed Manhole Cover 16 material includes Base Color, Height, Mask, Metallic, DirectX Normal, and Roughness maps. The site also provides the open-source Texture Tiling Tool, which helps make photoscanned surfaces seamless and repeatable through surface-aware blending, clone patches, and lighting equalization at seams. Guides cover Blender and Unreal Engine setup. The Blender guidance notes that DirectX normal maps need green-channel inversion for Blender’s OpenGL format. Sample Rock and Bark downloads are offered in 4K and 8K, with file sizes from 118MB to 958MB. Patrons can access a Google Drive folder containing all textures.
