So, I am making my own texture pack. However, I have run into the problem that all the stone textures tile horribly. Either you can see distinct lines between each block, or you can see a very noticeable pattern in the blocks. I really don't want either of these, so what is the best way to make stone so that it doesn't have either of these?
It really depends on the type of texture. You've got two main things to utilize, the make seamless filter and the ability to offset layers. The make seamless filter is under filters>map, and what it basically does is blend the center of the image to replace the corners (it's difficult to explain, really. The offset is under layer>transform, and well, it offsets the image. Make sure wrap around is selected under edge behavior (I believe it is by default). If you click the offset by 2/x, 2/y button it makes it so that the edges of the layer are now in the middle of the image.
I suggest you get a picture and play around with the tools, just to see what exactly it does. Use a picture that clearly isn't meant to tile so that you can get a better understanding. Also, something I do on occasion when I use the make seamless filter is I duplicate the original layer and use the filter on the second one, then erase parts of that so the image is less blurry where the blending was done, and if it's supposed to be something like tiles, so that they can align right.
Also keep in mind that they're used in different situations. If you're doing pure pixel art, you can probably only use the offset tool. If you're also incorporating other textures and using photo editing techniques, then make seamless will be more helpful sometimes.
In case it matters, I use GIMP for my textures.
