Hi,
I have created a shader holding multiple SHADERLINK 's. It is some kind of Layers and Alphamaps. My shader needs get colors of those SHADERLINK 's. Each SHADERLINK is holding BaseLink 's to Xbitmap shader.
The output routine of my shader needs to render some Xbitmap 's first and combine those color to final color.
I am holding BaseList2D* (e.g. diffuse, alpha1, ... ) for each SHADERLINK. Each of them has type=5833 means Xbitmap.
Question: How to render Xbitmap 's I cant find any class or derivation of XBitmap.
Vector MyShader::Output(PluginShader *chn, ChannelData *cd)
{

if(diffuse==NULL)
    {
      return Vector(0, 1, 0);
    }

Vector c = ((PluginShader* )diffuse)->Sample(cd);
    float col[3];
    col[0] = c.x;
    col[1] = c.y;
    col[2] = c.z;

return Vector(col[0], col[1], col[2]);

}

Final color is always black even if Xbitmap is all red.

Greetings

Jimbo

thx
that's it, calling InitRender and FreeRender solved my problems
