Question How to add secondary textures settings to Sprite Atlas through C#?

Hello!
I have an automated system (Unity 2020.2.0f1) where I pick a bunch of separated sprites with a secondary Normal Map, and I add them to a generated SpriteAtlas asset. Works good, but the normal map needs to have the sRGB option uncheked.
In the editor, this is done through the Secondary Settings panel:


However, since this is an editor script, I need to add this secondary settings through C#, but I don't find any method nor documentation to do this.
What I do right now is:

Code (CSharp):

1. atlas.Add(spriteFiles.ToArray());
2.  
3. //This texture settings are only for the primary texture. Is there a way of doing the same to the secondary Normal Map?
4.         SpriteAtlasTextureSettings newTextSettings = new SpriteAtlasTextureSettings();
5.         newTextSettings.filterMode = FilterMode.Point;
6.         newTextSettings.sRGB = true;    
7.         atlas.SetTextureSettings(newTextSettings);
8.  
9.         TextureImporterPlatformSettings newPlatformSettings = new TextureImporterPlatformSettings();
10.         newPlatformSettings.textureCompression = TextureImporterCompression.Uncompressed;
11.         atlas.SetPlatformSettings(newPlatformSettings);
12.  
13.          AssetDatabase.CreateAsset(atlas, atlasPath);
14.         AssetDatabase.SaveAssets();

Is not the biggest of the deals (the script already lifts a lot of work for me), but I would like to spare me some repetitive clicks.

 

in this code you don't seem to be accessing

SpriteAtlas

object, but

SpriteAtlasAsset

.

SpriteAtlas

does not have

SetTextureSettings

and

SetPlatformSettings

.

it makes sense to show your entire code, not just a misleading part of it.

 

"atlas" is a SpriteAtlas. SetTextureSettings and SetPlatformSettings come from Sprite Atlas Extensions.

 

Ah ok right, it's an editor-only thing. I apologize then, this thing really has documentation all over the place.

 

Did you find a solution to this? Seems the only way to do it is SpriteAtlasExtensions.SetSecondaryColorSpace() which is internal.
