Set normal map at runtime in Unity

I have a trouble setting normal map via script in unity. I have a normal map and I want to assign it to a material of the target object.

renderer.material = new Material(oldMaterial);    
renderer.material.SetTexture("_BumpMap", normalTexture);

This line works for assigning the texture. But the target object's normal map is not updated until I open inspector and click material component. I can update albedo texture by using this technique and it works.
Is there a function to force material update its properties ? Any ideas?

Solution

  • Try add that one:

    renderer.material.shaderKeywords = new string[1]{"_NORMALMAP"};
