Let me explain why i'm asking this.
Sometimes i start with a project with some old tgc files and i put them together and try to create a new view.
From then, as i don't think the first view could be the best, i try to modify some seeds.
On a project, i try to change the fractal terrain seed. Rather than using the random, i start from 1 and increase until it seems good in the preview window.
Then I make a quick render and i save it with the seed information.
This morning i was doing this and finishing a render with seed 315. Immediately it came to my mind that i saw this view recently.
Checking my other renders i admit that seed 59 and 315 are exactly the same. Not long to see that between 59 and 315 the gap is 256.
So i check with the opening terrain in tg3 seed 119, seed 375 and seed 631 are the same.
Then my question is : is there a useful limitation to 256 and rather than random can we only check between 1 and 256 for any seed to get the more appropriate ?
