Each variation shares the same edges as the first texture, so each variation tiles to each of the other six. 18 Seven variations which all tile together Note that the use of variations doesn't obviate the need to practice the fundamental areas listed above. Indeed, in some cases, they become even more important. Creating variations usually entails bringing together elements from disparate sources, and so it is crucial that the color and value of those elements be consistent across all variations. Directional elements must now be considered, as they occur across all the variations, not just within a single texture where such elements are usually easiest to control.
Direction cues from disparate elements.
Other considerations, like value and noise come into play as well. The introduction of variants lessens the need for absolute attention to an even distribution of noise values, as the variants themselves break up repeating clumps. As can be seen in Fig. While the variations don't create a pattern per se, if certain elements are noticed often enough, immersion can be just as broken as with an atrociously repeated single texture. A good number of the elements in Fig.
