Sampler Source -> Shared: Wrap and Shared: Clamp for Texture Objects too

[Haoris]

@Chosker

in those cases you’ll need to modify the Custom node so that the HLSL code samples the texture with Shared Wrap

Do you know how to change the code to use shared wrap? The custom node code is :

float rayheight=1;
float oldray=1;
float2 offset=0;
float oldtex=1;
float texatray;
float yintersect;
int i=0;

while (i<MaxSteps+2)
{
texatray=dot(HeightMapChannel, Tex.SampleGrad(TexSampler,UV+offset,InDDX, InDDY));

if (rayheight < texatray)
{
float xintersect = (oldray-oldtex)+(texatray-rayheight);
xintersect=(texatray-rayheight)/xintersect;
yintersect=(oldray*(xintersect))+(rayheight*(1-xintersect));
offset-=(xintersect*UVDist);
break;
}

oldray=rayheight;
rayheight-=stepsize;
offset+=UVDist;
oldtex=texatray;

i++;
}

float4 output;
output.xy=offset;
output.z=yintersect; output.w=1;
return output;
