Unity3d 如何将发射添加到Unity water着色器?
我这里(又)有一个水着色器。多亏了你,我的另一个问题才得以解决。现在我的水不再透明了。因为你们有很好的知识,我希望你们能帮我向着色器添加发射。如果波浪的顶部有一些高光,那就很酷了。也许它可以使用一个发射地图,但只是一些发射将是非常酷看我认为 我试着写这首独奏曲,但对我没用Unity3d 如何将发射添加到Unity water着色器?,unity3d,shader,Unity3d,Shader,我这里(又)有一个水着色器。多亏了你,我的另一个问题才得以解决。现在我的水不再透明了。因为你们有很好的知识,我希望你们能帮我向着色器添加发射。如果波浪的顶部有一些高光,那就很酷了。也许它可以使用一个发射地图,但只是一些发射将是非常酷看我认为 我试着写这首独奏曲,但对我没用 _EmissionLM ("Emission (Lightmapper)", Float) = 0 [Toggle] _DynamicEmissionLM ("Dynamic Emission (Lightmapper)"

我自己从来没有这样做过,但似乎你可以添加一个“元”通行证,并以这种方式添加排放。资料来源:
