Help! 4k texture has seams when downsized in PS

Doomathon

Hi all, I'm working on a seamless texture in 4k res, and whenever I downsize it to a 2k or 1k map, there is always a tiny seam that appears. It is seamless when offset in 4k. I have tried placing a 128,128,255 RGB behind it and the seam disappears but when I merge the layers, the seam comes back.

I baked this from 3ds Max as a TGA, and edited it in PS CS6.

Any help would be wonderful with this frustrating problem. :poly127:
Thanks.


Here are the seams when four 2k maps are tiled, downsized from the 4k.

I've had this problem before. What I do is duplicate the layer 4 or 5 times and collapse them all into one. Should get rid of the seams.

Thanks for the help Drew++! What I did was downsized it to a 2k, offset it by 1024 and I got rid of the seams by duplicating the layer. Unfortunately, when I downsized it again to a 1k, the seams appeared again... I'll keep playing around with it.

That's coz you're on a layer while you should resize a "background"
Layer > Flatten image before resizing.

I think that did the trick! Thanks a lot for your help guys.

Does changing the scaling method help?

I've both manually scaled down with the transform tool, and just re-sizing the entire image. If there is a different/better method, I'm all ears!!
