Hi,
before with Beta/DX11 I was doing this :
float4 pBlender(float4 PosWVP: SV_POSITION, float2 uv: TEXCOORD0): SV_Target
{
float4 color = float4(0.0, 0.0, 0.0, 1.0);
for(int i = texcount-1; i>=0; i--)
{
float4 col = texArray.Sample(s0, float3(uv, LayerID[i]));
col.a *= Alpha[i];
if (BlendMode[i]==0){color=bld(col,col,color);}//NORMAL
if (BlendMode[i]==1){color=bld(color+col,color,col);}//ADD
if (BlendMode[i]==2){color=bld(color-col,color,col);}//SUBSTRACT
if (BlendMode[i]==3){color=bld(max(color,col),color,col);}//LIGHTEN
if (BlendMode[i]==4){color=bld(min(color,col),color,col);}//DARKEN
if (BlendMode[i]==5){color=bld(color*col,color,col);}//MULTIPLY
}
return float4(color.rgb * transition, color.a);
}
The BlendModes don’t matter for now and it also doesn’t have to be a TextureArray, maybe an other way is possible in Gamma.
Testing with just 4 textures, this is what I thought it should look like :
Problem is, I have no idea how to set a default texture (or color?) the way I did it in HLSL before the loop and I don’t get the result I expect which would be one final texture…
Any hint ?
Thx.
