对于我的项目,我需要在运行时创建材料。当我创建材料时,法线贴图没有效果。我尝试了两种解决方案,但它们对我不起作用。在Unity 5中是否有所改变?
我查看的链接:
http://answers.unity3d.com/questions/801670/runtime-loading-normal-texture.html http://answers.unity3d.com/questions/47121/runtime-normal-map-import.html
附言:奇怪的是,当我在Unity中切换到“场景视图”时,如果我从“检查器”扩展材质选项卡,则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;
}
