Hi,
I wanted to try out Flat Shading in my DX9 app and tried to activate it with this line:
HRESULT hr = mDevice->SetRenderState(D3DRS_SHADEMODE, D3DSHADE_FLAT);
hr is S_OK.
But my 3D world looks exactly the same. All the polygons are textured and look as if rendered with D3DSHADE_GOURAUD.
Does anyone know why setting the shade mode to Flat does not change anything in my rendering?
Flat Shading is ignored
Are you using the fixed function pipeline or shaders?
If I'm not mistaken, D3DRS_SHADEMODE affects only attributes with D3DDECLUSAGE_COLOR, so if you were calculating the color in a pixel shader, the shademode could really make no difference.

I only use Pixelshaders. Interesting, so when using shaders the render state D3DRS_SHADEMODE has no effect. Did not know that. Thanks for your answer Tom KQT!
I had a bad feeling about it, but wasn't sure. I found it here: http://msdn.microsoft.com/en-us/library/windows/desktop/bb147365%28v=vs.85%29.aspx
