Alpha Test 示例

This material graph sample demonstrates how to use alpha testing when creating materials.此材质图表示例演示了如何在创建材质时使用 alpha 测试。

The Sample Texture node samples data from an RGBA texture (Texture 2D node) in accordance with the default UV and passes RGB color components to the Albedo port of the master material node of Mesh Alpha Test PBR type (first three components are taken) while passing Alpha data to the Opacity port via the w port adapter.Sample Texture节点按照默认UV从RGBA纹理（Texture 2D节点）采样数据，将RGB颜色分量传递给Mesh Alpha Test PBR类型的主材质节点的Albedo端口（取前三个分量），同时将Alpha数据传递给Opacity通过 w 端口端口适配器.

Normal data for the material is taken from the tangent-space Normal map data (Texture 2D node) sampled by the Sample Texture node.材质的 Normal 数据取自 Sample Texture 节点采样的切线空间 Normal 贴图数据（Texture 2D 节点）。

Translucency of the resulting material is controlled via the Slider node (enabling you to adjust a float value via the Parameters panel in UnigineEditor) connected to the Translucent port of the master material node.生成材质的 Translucency 通过连接到主材质节点的 Translucent 端口的 Slider 节点（使您能够通过 UnigineEditor 中的 Parameters 面板调整浮点值）控制。

Finally, the data output is passed to the Final node.最后，将数据输出传递给 Final 节点。

The result结果
