Instancing with custom Stride DrawFX shader

[lecloneur]

Hello,

here is a simple shader for instancing :

shader Instancing_DrawFX : VS_PS_Base, Texturing, InstanceWorldBuffer  
{
    [Color]
    float4 Color = float4(1, 0, 0, 1);


    override stage void VSMain()
    {
        float4x4 w = InstanceWorld[streams.InstanceID].Matrix;
        w = mul(w, World);
        streams.ShadingPosition = mul(streams.Position, mul(w, ViewProjection));
    }

    override stage void PSMain() 
    {
        streams.ColorTarget = Color;
    }
};

And this the test patch for it :

I might be wrong but it seems that this line isn’t “working” :
float4x4 w = InstanceWorld[streams.InstanceID].Matrix;

Any hint ?

Alright just find out.

needed to set the hidden pin IsStructuredBuffer to true on the DynamicBuffer node.
