Material Rendering Mode broken?

Unity Engine
1

Currently i am using gameObject.material.SetFloat( “_Mode”, 1 ); which actually sets the rendering mode of the material… but nothing happens… it does work however when i manually set it…

Is this known?

See here. The manual way does a few more things behind the scenes. Below is essentially the relevant code to accomplish what you want for each rendering mode (taken from built-in shader source code):

// opaque
material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.Zero);
material.SetInt("_ZWrite", 1);
material.DisableKeyword("_ALPHATEST_ON");
material.DisableKeyword("_ALPHABLEND_ON");
material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
material.renderQueue = -1;

// cutout
material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.Zero);
material.SetInt("_ZWrite", 1);
material.EnableKeyword("_ALPHATEST_ON");
material.DisableKeyword("_ALPHABLEND_ON");
material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
material.renderQueue = 2450;

// fade
material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.SrcAlpha);
material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);
material.SetInt("_ZWrite", 0);
material.DisableKeyword("_ALPHATEST_ON");
material.EnableKeyword("_ALPHABLEND_ON");
material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
material.renderQueue = 3000;

// transparent
material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);
material.SetInt("_ZWrite", 0);
material.DisableKeyword("_ALPHATEST_ON");
material.DisableKeyword("_ALPHABLEND_ON");
material.EnableKeyword("_ALPHAPREMULTIPLY_ON");
material.renderQueue = 3000;
