unityexception at reading a texture in script

Hi

I get this exception, not when compiling but when running

UnityException: Texture ‘viking_mergedS-500-500_color’ is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.
UnityEngine.Texture2D.GetPixels (Int32 x, Int32 y, Int32 blockWidth, Int32 blockHeight) (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/TextureBindings.cs:244)
MeshWorldBuilder.inserttexture () (at Assets/TileMapGraphics/MeshWorldBuilder/MeshWorldBuilder.cs:88)
MeshWorldBuilder.Start () (at Assets/TileMapGraphics/MeshWorldBuilder/MeshWorldBuilder.cs:20)

It says that the texture memory cannot be accessed from scripts and that I can make the texture readable int the texture import settings. Where do I find the texture import settings?

thx, though it did take me a while to find a useable answer with your google search.

That’s the first result I am getting, which has the correct answer.
