I've tinted the three layers differently here to show what is what:įeather the edges of the third layer using a very large and soft brush:

This is just a quick and dirty demonstration and the result is not good enough to keep but it should illustrate the principle.Ĭopy, double the width of the image and paste into new layer:Ĭreate a third layer, paste the texture into it and move roughly to the middle of the image. (Edit: Yes, this texture is only seamless horizontally but it's the same principle anyway.) since they tend to either blur parts of the texture or add noticeable artifacts or - as often as not - both. I'm not to happy about the automatic seamless functions included in many image editors either btw. This is actually one of the very best 'mirrored seamless' textures I've seen and it's still not quite up to the standards I think we should aim for in SL today. I've never been happy with that solution because the mirror effect tends to be very noticeable. (Their patent has expired now, so no worries.) That's one of the original methods, patented by Pixar. Resize the big image to 512 x 512, save as png - no transparency (unless you have alphas) Select and copy, paste into the bottom left corner of the big image.

Select and copy, paste into the bottom right corner of the big image In the small image, choose 'flip vertical' Select and copy, paste into the top right corner of the big image In the small image, choose 'flip horizontal' Select and copy this image, paste into the top left corner of your big image. Paste the cropped selection into a new image, resize it to 512 by 512

(can be done in but I find their square selection less easy to use) In Irfanview or similar, crop the texture you would like to be seamless.
