very flat fbx objects disappear in game view?

Questions & Answers
1

Hello again!

This time, my problem has to do with rendering as I believe…
I added some very thing .fbx waterfalls pouring down from some floating island (think Nagrand whoever played WoW) and they look really nice, however most of the time you can’t see them. The island has a circular shape, and from it 3 waterfalls streak down, each in a different direction.
In game view, I can only see one waterfall at a time, and the other two are invisible… However when I rotate my camera around so one of the other two is in focus, the first one disappears (and the third stays invisible)
When zoomed out in scene view I can see all the waterfalls…
How do I set everything up so those flat objects dont disappear? (they really are quite thing…)

Thanks!

Sounds like z-fighting. Try using a shader that includes an offset. Simple example:

Shader "No More Z Fighting/Foreground Element" 
{
 Properties
 {
 _MainTex ("Main Texure (RGBA)", 2D) = "" {}
 }
 
    SubShader 
    {
        ZWrite Off
        Offset -1, 0 // This is the important part to avoid the Z Fighting
        Blend SrcAlpha OneMinusSrcAlpha
        
        Tags { "Queue" = "Transparent" }
            
        Pass 
        {
            SetTexture [_MainTex] { combine texture }
        }
    }
}

rather your issue is in geometry facing. you flat object should use double-sided shader or have two faces to be visible from both sides.

  • so solution 1 - improve shader that you use for it
  • solution 2 - make some more geometry
