Tiling in Gimp

I thought I had found a way to tile my texture in Gimp, so that it is symetrical. So, if I use it in adjacent prims, the edges match. I've been looking and looking, but can't seem to find how to do that. Anyone has it figured out? TIA!

I don't know about gimp but I use Photoshop and if the texture is equalateral on all four sides I just just make 4 copies and then underlap overlap until I find their edges and possibly a little strecthing or shrinking is required.

Normally I create a new file that is at least 4 times bigger than the one I am working on to make things quick.

If it is not equalateral then I use the clone tool, plugins or filters depending again on the texture design.

Sorry that I can't help with Gimp directly but if your working in layers then surely should be the same...

I think equalateral is the wrong word I used, I mean't to say, for example, if you design a single floor tile, top or bottom must have grouting and left or right must have grouting then it would be seamless and tileable.

I think what you want is at http://www.highpoly3d.com/writer/tutorials/tileable/seamless.htm

I'm not real sure what you want to do but in your image window with your image or texture selected, pull down the "filters" menu, to "map" and then choose "make seamless".

That will flip your texture both horizontally and vertically which makes all four sides the same so the texture can be tiled with little or no seams.

A good way to tile your texture is once you have your texture seamless, go the "script fu" menu and choose "selection to pattern". Then use bucket fill with "pattern" as your source (the pattern you just made usng the script fu). Oh and be sure to name your new pattern unless you want a bunch of "my patterns" sort through.

The manual way is to go to layer/transform/offset, and shift the edges of your texture to the middle. Then use tools such as the clone stamp to erase the line in the middle. There is a photoshop tutorial in these forums, but the Gimp works the same way.

The advice to Make Seamless will also work.

There are also a couple of Texturize plug-ins that do amazing things.

Google for GIMP seamless

You can look here http://www.flickr.com/photos/leeponzu/sets/72157600270392611/ for some examples that I have made.

Firstly I usually make sure the image I want to tile is sized to the correct dimensions. eg 128x128 or 128x256 or whatever, but similar to that same principal.
Then do Filters>Map>Make Seamless.
Then , Filters>Map>Tile to required size.
Or, as mentioned, make seamless and Script-Fu>Selection>To Pattern
