Unity 5 中的运行时法线贴图导入

Ber*_*tas 6 c# unity-game-engine normals

对于我的项目,我需要在运行时创建材质。创建材质时,法线贴图不起作用。我尝试了这两种解决方案,但它们对我不起作用。在 Unity 5 中对此有什么改变吗?

我检查的链接:

PS:奇怪的是,当我在 Unity 中切换到“场景视图”时,如果我从“检查器”中展开材质选项卡,法线贴图将应用于对象。

我的代码:

            ....
Material mat = new Material(Shader.Find("Standard (Specular setup)"));
mat.SetTexture("_MainTex", colortex);

normaltex = getNormalTexture(Texture2D source);
mat.SetTexture("_BumpMap", normaltex);
mat.SetFloat("_Glossiness", 0.1f);
mat.SetFloat("_BumpScale", 1.0f);

            ....             

public static Texture2D getNormalTexture(Texture2D source)
{
    Texture2D normalTexture = new Texture2D(source.width, source.height, TextureFormat.ARGB32, true);
    Color theColour = new Color();
    for (int x = 0; x < source.width; x++)
    {
        for (int y = 0; y < source.height; y++)
        {
            theColour.r = 0;
            theColour.g = source.GetPixel(x, y).g;
            theColour.b = 0;
            theColour.a = source.GetPixel(x, y).r;
            normalTexture.SetPixel(x, y, theColour);
        }
    }
    normalTexture.Apply();
    return normalTexture;
 }

至少在 Unity 4.x 中,您必须修改着色器才能正确显示运行时法线贴图。只需从代码中删除 UnpackNormal() 即可。
