I am not expert, but as I know there is no “good” solution to transparent materials. I have an existing shader which uses vertex animation to deform a mesh at render time using previously created position and normal vertex maps. If you use a texture for Albedo instead of a color, by default the alpha channel of the texture controls the transparency of the material. My texture has parts where the alpha is exposed and the transparency helps the texture to have its unique shape. I found one posted by gnoblin on this thread that performs that function perfectly. "#pragma surface surf Standard vertex:vert fullforwardshadows keepalpha" This WILL make your shader transparent (even if it’s alpha=1, the shader’s ‘Rendering Mode’ is equivalently set to Transparent, so you might notice the depth is ruined (as it should be since it’s transparent) 3. 5.

In the second option, the GPU multiplies the color by the alpha in the shader execution hardware. Overlapping shadows Transparent Diffuse shader-TransDiffuse. Alpha to the target value, but remember to tell the shader that it is part of the Transparent group (so it is part of the transparent render queue). Apr 22, 2022 · Enabling semitransparency makes the generated surface shader code contain blending commands; whereas enabling alpha cutout will do a fragment discard in the generated pixel shader, based on the given variable. 2), the overlapping area becomes darker due to the blending. It shows up correctly in the editor view. (For the built-in shaders, you would have to download the zip file with Unity’s built-in shaders, edit them and then use the edited shader in your project.
