Seamtile
Turn photos into seamless repeating textures. A free Mac app
Drop in photos of ground, grass or fallen leaves
Seamtile builds a texture that tiles in every direction — plus a normal map and a height map — all automatically
Made for ground textures in games and 3DCG
Grow your own textures
No need to keep buying texture packs
No need to keep paying for subscriptions
Textures are something you go out and collect
All you need is a phone
Leaves under your feet, the gravel path down the street, the lawn out back — shoot it and it’s yours
Zero monthly fees. Zero worrying about cancelling
Lost a texture? No big deal
Just go shoot another one
Say goodbye to annoying licenses
When your textures come from your own photos, there’s no fine print to read and no credit lines or commercial-use terms to puzzle over
CG built from textures you gathered yourself just feels better
Go on, start growing your own
Features
Drop in photos, get a tile
Finding the usable area, matching colors, stitching and fixing seams all happen on their own
No settings to learn
AI leaves out what isn’t the material
Tree trunks, sky, walls — the AI spots what you didn’t mean to capture and leaves it out
Shoot without worrying about what’s in the frame
Recognition runs on your Mac, so your photos never leave it
Sorts a whole day of photos
Drop in a folder and Seamtile groups photos by material and look
Then it makes one tile per group
Normal and height maps included
Saves color, normal and 16-bit height maps together
Choose OpenGL or DirectX normal map orientation
How it differs from other texture tools
Seamtile is built for turning lots of photos into textures with almost no handwork
| Seamtile | Typical texture tools | |
|---|---|---|
| Adding photos | A whole folder at once | Usually one photo at a time |
| Choosing the area | Automatic (touch up with a brush only where needed) | Often masked by hand |
| Sorting photos | Automatic, by material and look | You sort them yourself |
| Many photos into one tile | Colors matched and blended naturally | Often one photo per texture |
| Where photos go | Nowhere — they stay on your Mac | Some tools process in the cloud |
