MA_TextureAtlasser review

Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026

MA_TextureAtlasser is an open-source Unity editor tool for combining textures and sprites into atlases or sprite sheets. Its distinctive role is bridging 2D packing with 3D asset preparation: it can remap UVs on assigned meshes to the new atlas, then export Unity meshes with prefab setup. That makes it a fit for Unity users who need to reuse texture space across sprites and 3D models, especially solo developers and small teams. It is less suited to people seeking a general-purpose sprite-sheet workflow outside Unity or a tool centered only on 2D animation assets.

A visual editor lets users set and prioritize texture sizes and positions. Output includes PNG textures and sliced PNG sprite sheets, alongside Unity meshes with prefab setup and materials carrying assigned textures and a selected shader. These options make the tool more than a basic image packer when the target project includes Unity meshes; teams that only need a flattened sheet may not benefit from that additional 3D-oriented workflow. The repository says the latest release requires Unity 2018.3 or later, while earlier releases may work with older Unity versions, so version compatibility is relevant before choosing it.

The product is open source, has a free plan, and is self-hosted, with versions for Windows, macOS, and Linux. That gives users a desktop option across those operating systems, but it also means the workflow is tied to installing and using the Unity editor tool rather than a hosted service. Choose MA_TextureAtlasser when atlas creation and UV remapping belong together in a Unity pipeline. For a broader sprite-sheet workflow that does not involve Unity meshes, a more general tool may be a better fit.
