Set wrap mode to clamp

Hi,
I'm creating an editor script to generate a gradient texture from a gradient field. I want to set the wrap mode of the newly created texture to clamp.

I tried setting the texture.wrapMode before calling Apply(), tried after, tried loading the asset and changing it. Nothing seems to work, the wrap mode always stays to repeat.

What am I missing?

Thanks!

Code (CSharp):

1.        
2.  
3. Texture2D texture = new Texture2D(width, height, TextureFormat.RGBAFloat, false);
4.  
5. for (int x = 0; x < width; x++)
6. {
7.        var color = grad.Evaluate((float)x / (float)width);
8.        Color[] colors = Enumerable.Repeat(color, height).ToArray();
9.        texture.SetPixels(x, 0, 1, height, colors);
10. }
11.  
12. texture.wrapMode = TextureWrapMode.Clamp; // Set the wrap mode
13. texture.Apply();
14.  

 

Maybe try reverse the order of line 12 and 13, in case the .Apply() actually caches some previous values and overwrites the wrap mode... just a thought.

 

Yeah I tried that, doesn't help unfortunately.

 

how is that texture mapped? how do you test whether it works?

 

Omg, I forgot to mention the most important!

This is a texture that I physically create on the hard drive using this:

Code (CSharp):

1.        
2.         byte[] bytes = texture.EncodeToEXR(Texture2D.EXRFlags.OutputAsFloat);
3.         File.WriteAllBytes(savePath, bytes);
4.         AssetDatabase.Refresh();
5.  

so the import settings remains to repeat and this is what I want to change not using an asset preProcessor if possible.

 

great. yes that's it, you want to change the import settings, not the object in memory.

 

yes, is this possible to do from an editor script without an asset preprocessor?

 

try TextureImporter

 

Ho yeah, I didn't know how to use that outside the preprocessor, but I found out.
Thanks!
