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 don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
