How would this be done if you wanted the texture to be slightly different at different places in the image?


Are there different ways we can add randomness to the textures to make it look more natural? Or do we just assume that an audience will not look carefully enough to notice that its repetitive?


^^In response to this, do "random" textures actually look more natural? I feel like there is some part of the human brain that looks for repetitiveness and patterns to understand a texture.


Is there any convention / tricks to blend two adjacent textures? The provided textures in this slide blend very well with each other, but what happens if that's not the case?
