GUITexture makes my image to low quality

GUI.DrawTexture is ok but the other thing throw down the image quality

I need to draw a fullscreen texture.
If I use GUI.DrawTexture all is ok but for other reason I need to use a GUITexture.

The problem is that with GUITexture the image quality is very low (with DrawTexture its ok) and I have to greatly increase “the size” of the image to increase a bit the quality.

Have you change the type of texture in your assets? Click on your image and in the inspector menú you will see “Texture Type” option then sellect GUI and apply changes.
