Help with making custom Textures/Materials?

[Mindmixer]

First off, I'd love if you guys could tell me the difference between a texture and a material.

 

Secondly, what is the best size for a texture or material if I'd make it using Paint.Net? (a square? e.g. 100pixels by 100pixels?).

 

Thanks!

1-st material is a default "material" of a object or whatever model in the 3D space of your favorite 3D redactor (i.e: Blender)  and it could have ANY color you like.
2-nd Texture is a surface diffuse/normal/specular color based on the texture itself (except the normal map parallax and specular textures cost it use the effect of it purpose and NOT the color that its have!
And 3-rd... how you can be a game-dev or 3D designer that did known the simple and based rule of that? )

Textures do not have to be square in this version of le but a good size might be 512 x 512.

If you download gimp you will find it has tools for making diffuse and normal textures and also a " make seamless" menu option for making textures seamless.
