hello, this is my first post here and its a bit of help i need, i downloaded a tree bark texture, then made a tree trunk out of a terrain,then applied the bark texture but i cant seem to get it to cover the trunk without repeating itself at certain intervals, the picture will show what i mean, i would appreciate any help on how to solve this,ive read loads of tutorials but cant seem to figure this one out thank you

When looking for photos ie: .jpg or .bmp texture...you need to make sure that it is "Seamless". There are a few texture sites that list if they are seamless or not.

Another quick way to check of you texture is seamless is make is smaller than your screen resolution and apply it as you desktop background, Choose tile image too you will either see the seams or not. If you have Adobe photoshop it has some built in functions for creating seamless textures just look in the help file I think it is even a tutorial of thier not sure though but lots of info on it just search the web

You can adjust the size of the texture in the material editor. Try playing with the Y size to start, depending on how much you have to stretch it it may distort or become pixelated (depends on the textures original size).

Easiest thing may be to try and make it seamless (in the vertical sense) yourself. To do this.... load the jpg you used into a paint program, then get a mirror image of the jpg (mirrored about the bottom of the image - not the side). Then append this mirrored image to the bottom of the original un-mirrored jpg and use that as the basis of the new texture. This way, the combined image will have the same colouring at the top and bottom of the image, so no seams (running across the tree trunk) will appear. Hope that makes some sense.

To make an image seamless in both directions take it into Photopaint of Photoshop and apply the offset filter set to 50% in both directions. This brings the seams to the center of the image where the make a cross. Then use the blend and clone tools to remove the cross.

Or... create a new doc 4X the size of your texture, and put... top left - your texture bottom left - texture mirrored vertically top right - texture mirrored horizontally bottom right - texture mirrored vertically and horizontally

thankyou for the help, the problem was seams
