Hm... I'm curious now, was size the issue of it tiling correctly? Or just aligning it to come out right? I'm always interested in other people's wall/floor making experiences, because very few people seem to actually care about how easy or difficult it is to make walls. Or else they lie, like certain people at TSR who claim to hand paint all her walls/floors yet uses patterns I've seen elsewhere.
Well, I was taking some interesting looking paper scans and turning them into wallpaper. I liked the patterns, and I though the fact that it was paper would lend it some realistic texture (and I was right), but several of them had complicated patterns so add in that + slight variations from physical scanning + the warp adjustments being a pain in the ass in PSP compared to the Photoshop ones in the tutorial I was following, and it was just a pain.
I later found out it was easier to just get it pretty close, do an offset, and then paste the pattern over the minor seam I had in the middle. I'm pretty anal about the seams, too, which is funny because I have a couple walls that I like to use that other people have made with a little bit of visible seaming, and I don't mind.
Here are very quickly done previews, if you want to see them:
The very first wall is the one I spent a couple hours on, trashed, and came back to later. It was still a pain in the ass. Others took no time at all, so I'm sure it was relative to the scanning job. In retrospect, it might've been easier for me to copy paste the first one into a tiling texture than playing with the scanned texture.
I admire that you can work with the cloning tool. I still don't know how that one works!
It has rather limited applications. I mainly use it to edit out snippets of the action queue in screenshots, actually! But on the wallpapers, I used it to replicate background texture near areas where I pasted bits over seams. Since I wanted to keep the texture.
