| | When I created my VertexPositionNormalColored type I used position, normal, then color like this
public Vector3 position;
public Vector3 normal;
public Color color;
public static VertexElement[] VertexElements =
{
new VertexElement(0, 0, VertexElementFormat.Vector3, VertexElementMethod.Default, VertexElementUsage.Position, 0),
new VertexElement(0, sizeof(float)*4, VertexElementFormat.Vector3, VertexElementMethod.Default, VertexElementUsage.Normal, 0),
new VertexElement(0, sizeof(float)*3, VertexElementFormat.Color, VertexElementMethod.Default, VertexElementUsage.Color, 0),
};
instead of position, color, normal and when I set the normals, it created a crazy mess of colors where shadows should be. Why should it matter the order of the VertexElements when the vector3 and color types are defined in the same order? | |

Should instead be:
new VertexElement(0, sizeof(float)*3, VertexElementFormat.Vector3, VertexElementMethod.Default, VertexElementUsage.Normal, 0),
new VertexElement(0, sizeof(float)*6, VertexElementFormat.Color, VertexElementMethod.Default, VertexElementUsage.Color, 0), |
You're offseting your normal data too far into the stream, and your colour data not far enough. | |
