importer.GetNPOTScale() == TextureImporter::kNPOTKeep

[wijesijp]

When I try to bring any images to Atlas Maker I get following error

I am using Unity 4.6.5
NGUI 3.8.2

Any suggestions on how to fix this?

1. importer.GetNPOTScale() == TextureImporter::kNPOTKeep
2. UnityEditor.AssetDatabase:ImportAsset(String, ImportAssetOptions)
3. NGUIEditorTools:MakeTextureAnAtlas(String, Boolean, Boolean) (at Assets/NGUI/Scripts/Editor/NGUIEditorTools.cs:489)
4. NGUIEditorTools:ImportTexture(String, Boolean, Boolean, Boolean) (at Assets/NGUI/Scripts/Editor/NGUIEditorTools.cs:503)
5. NGUIEditorTools:ImportTexture(Texture, Boolean, Boolean, Boolean) (at Assets/NGUI/Scripts/Editor/NGUIEditorTools.cs:522)
6. UIAtlasMaker:ExtractSprites(UIAtlas, List`1) (at Assets/NGUI/Scripts/Editor/UIAtlasMaker.cs:555)
7. UIAtlasMaker:UpdateAtlas(List`1, Boolean) (at Assets/NGUI/Scripts/Editor/UIAtlasMaker.cs:687)
8. UIAtlasMaker:OnGUI() (at Assets/NGUI/Scripts/Editor/UIAtlasMaker.cs:1055)
9. UnityEditor.DockArea:OnGUI()

Seems to be related to the Power Of Two setting of the texture.

[wijesijp]

The textures, do they have to be power of two  ?

[r.pedra]

Nope

Do you have some other script or addon that has a texture post-processor? That would indeed cause a problem if it tries messing with textures while NGUI is using them.

I am experiencing this issue as well, even in a brand new empty project.

Unity 5.0.2f1
NGUI 3.9.0

This seems to only happen if the project was originally created in 2D mode.

[ArenMook]

Ah, 2D mode... Unity force-imports textures as sprites in 2D mode.

I tried switching to 3D mode, reimporting the files, and building the atlas again. No luck.

[ArenMook]

Select the atlas texture and manually change its import settings to use Advanced texture type, not sprite type.

Aha, of course. Thanks.
