I however got the model to load under tessellation; only problem is that one of the constant buffers aren't actually updating the shader's tessellation factor inside the hullshader.

I created a messagebox at the rendering point so I know for sure the tessellation factor is assigned to the dynamic constant buffer.

Inside the shader code where it says .Edges[1] = tessellationAmount; the tessellationAmount is suppose to be sent from the dynamic buffer to the shader. Otherwise it's just a plain box.

In better explanation; there's a matrixBuffer, cameraBuffer, TessellationBuffer for constant.

There's a multiBuffer array that assigns the matrix, camera, tesselation. So, when I set the Hull Shader, PixelShader, VertexShader, DomainShader it gets assigned by the multibuffer.

E.G. devcon->HSSetConstantBuffers(0,3,multibuffer);

The only way around the whole ideal would be to go in the shader and change how much the edges tessellate and inside the edges as well with the same number.

My question is why wouldn't the tessellationBuffer not work in the shader?
