LODGroup crossfade shader var issue

Hi,


I have some props that i want to nicely blend in to reduce the lod popping , i use lerping and clipping in my shader along with the built-in unity_LODFade float2.

Now it works perfectly however when the player is at 100% and keeps getting closer to the object the first dither mask appears instead of the full opaque mask (attached)

Here's my shader code (jsut standard with clipping function):

Code (CSharp):

1. void surf (Input IN, inout SurfaceOutputStandard o) {
2.  
3.             clip(lerp(tex2D (_Dither1, IN.uv_Dither1),
4.                 lerp(tex2D (_Dither2, IN.uv_Dither1),
5.                 lerp(tex2D (_Dither3, IN.uv_Dither1),
6.                 lerp(tex2D (_Dither4, IN.uv_Dither1),
7.                 lerp(tex2D (_Dither5, IN.uv_Dither1),
8.                 lerp(tex2D (_Dither6, IN.uv_Dither1),
9.                 lerp(tex2D (_Dither7, IN.uv_Dither1),
10.                 lerp(tex2D (_Dither8, IN.uv_Dither1),
11.                 tex2D (_Dither9, IN.uv_Dither1),
12.                 unity_LODFade.x),
13.                 unity_LODFade.x),
14.                 unity_LODFade.x),
15.                 unity_LODFade.x),
16.                 unity_LODFade.x),
17.                 unity_LODFade.x),
18.                 unity_LODFade.x),
19.                 unity_LODFade.x) - _SliceAmount);
20.                
21.                
22.             fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
23.             fixed3 n = UnpackNormal(tex2D(_MainTexn, IN.uv_MainTex));
24.             o.Albedo = c.rgb;
25.             o.Normal = n.rgb;
26.         }

Some more insight would be appreciated !
