The resource is modified by me, see post #16 - be careful
I suggest you a link to my seamless textures 128, 256, 512, 1024. And models - there are not many of them yet.
I will add information when at least 20 textures/models are updated.
All textures have both a normal map and a specular - d(n,s), except for those that require only diffuse, or normal.
In this topic there is a license - CC BY 3.0, as for examples / textures / models, and for help, anyone who does not like it - pass by - of course, all that after post # 22, all the textures that have proof of the original, like the examples with the specified license - CC BY 3.0
