阿诺德层阿尔法在哪里？

[力维_纪]

在阿诺德电影 4D 5.0.0 中， 层有阿尔法频道。但现在我找不到了我怎样才能找到阿诺德层阿尔法或它有其他方法来实现这种效果。谢谢，这对我很重要。

The layer_rgba shader can be used to mix textures and has an option to blend the alpha.

Thank you very much, but I want use black and white image to show the logo. And as we all know the white means protrude ,the white means concavity. Then I want the logo is gold. So this logic may First use black and white image to control the alpha ,Then use stander surface to control the white region looks like gold. This box may can show you the effect.2.jpg
