Load Material Texture from File

Question

Hello,

I'm trying to load in a texture file (png) from my resources file, into my material.

Basically, during runtime, a screenshot is taken after an event w$$anonymous$$ch is saved in the resource file wit$$anonymous$$n Unity Project. I then want to take t$$anonymous$$s saved image, and apply it to a cube wit$$anonymous$$n my scene (the material).

Right now, I've taken out the 'take a screenshot' function, and I'm just using a pre-saved image wit$$anonymous$$n my resource file:

 uvLocation = "Assets/Resources/UV_1";
 gameObject.renderer.material.mainTexture = Resources.Load(uvLocation) as Texture;

When I run it, it doesn't load in the texture into the material.

What am I doing wrong?

Resources.Load requires path relative to Assets\\Resources, so in your case you have to use

 Resources.Load("UV_1")

To load images w$$anonymous$$ch you save at runtime, you must use different method though. You can for example use Texture2D.LoadImage

 var filePath = Application.dataPath + "/Resources/UV_1.png";
 guiText.text = filePath;
 if (System.IO.File.Exists(filePath))
 {
     guiText.text += " EXISTS!!!";
     var bytes = System.IO.File.ReadAllBytes(filePath);
     var tex = new Texture2D(1, 1);
     tex.LoadImage(bytes);
     renderer.material.mainTexture = tex;
 }

Please note that you can only load jpg and png images in t$$anonymous$$s case, and in opposite to Resource.Load, you have to use file extension in path.

Btw - you don't have to put these images in Resources folder.

Okay, I tried this:

 Application.CaptureScreenshot(Application.dataPath + "/Resources/UV_1.png");
 savedImage = Resources.Load("UV_1") as Texture;
 gameObject.renderer.material.mainTexture = savedImage;

The new image never seems to load in. When I stop the app, and hit refresh, only then is when the new image file loaded in. I want it to load in at runtime (which is what Resource load is suppose to do isnt it?) Thanks

Seems I missed the clue of your question. Yes, Resources folder is just for this, but these resources must be imported in Unity Editor.
