Why not just copy paste three layers of the same image and the flipping em, going from 128x128 to 256x256 without even touching texture quality and making it tileable.
If you don't understand what I'm saying, as even I didn't:
We have this image:
128x128
make one identical layers flipping it horizontally, duplicating these two layers flipping both duplicates vertically, resulting in a completely tilable texture:
Because that texture is extremly easy to notice where it repeats. But, there isn't 1 sure-fire method for every type of texture. Your way is slightly better for those kind of rocks, but still require a large amount of re-touch work.
Your method is also better for lower-resolution textures, while mine begins to shine around 256+res. It's just opinion mate.
Indeed, that is true, I think my way looks good enough for brick walls, gravel and such, that doesn't need to look as unique as possible in every spot.
Btw I tested to tile your image vertically and it didn't fit in some places.
Some of you may not know this, but GIMP's printing script is very buggy right now. In fact, I can't print anything larger than about an inch square, so I found this neat trick for dealing with it while I was finding a program to print a picture. What you do is you save the file you want to print (I suggest a .png file format). Next, you go to your file and right click it. Go to open with and select firefox. Your image should be on the screen and you can just do file->print and voila, you have a program to print directly with.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
