Transparent shader with occlusion to the invisible parts of the model

[asdfasdf3]

Hi there,

I’ve got a 3d object that needs to be half transparent so that the objects behind it are visible; but I would like to get rid of seeing the back surfaces of the 3d object- so that the front surfaces occlude them; as they are all half transparent the back is obv visible atm and one can see the darker areas where the front and the back overlap. Does anyone have a solution?

THanks a million

You want a transparent shader with a separate depth pass. Like this:

Transparent shader with depth writes
https://docs.unity3d.com/Manual/SL-CullAndDepth.html

However you don’t want to use that shader, but rather a Surface shader with the separate depth only pass. There are some examples scattered across the forums, like in this thread:

Transparent Depth Shader (good for ghosts!)

So one of the things you will encounter when rendering complex meshs’ using standard transparent rendering is that they depth test against the scene, but not against themselves. This is a limitation of how depth tested rendering works and there are some ways to work around this issue. I’m going to talk about one of them, then show you how to do it in Unity. So lets start by rendering a scene that has some complex geometry (in this context I am using complex to refer to geometry where there are …

Also this one that is a modified version of the Standard shader with the same added depth only pass.

Several people asked me to post the “ghost” shader we use for bikes to fade them when they get close to the camera. This inderlying idea is very simple → it’s just the standard shader in fade mode with a depth write prepass. Once the depth buffer is updated, writing the fading pixels for the bike looks just like opaque mode, with a fixed alpha value. Here is a video showing what normal fade would look like, and what it looks like with the additional depth pass. [V racer Hoverbike - Uni…
