hi!

i've a problem with my meshes
in dxviewer it looks nearly how it should be:


but in my program the shading isn't like in the dxviewer (e.g. the lots are missing):


here are my parameters and my renderstates:

parameters.Windowed = true;

parameters.SwapEffect = SwapEffect.Discard;

parameters.EnableAutoDepthStencil = true;

parameters.AutoDepthStencilFormat = DepthFormat.D16;


dev = new Device(0, DeviceType.Hardware, this, CreateFlags.SoftwareVertexProcessing, parameters);

dev.RenderState.ZBufferEnable = true;

dev.RenderState.Lighting = true;

dev.RenderState.CullMode = Cull.None;

dev.RenderState.Ambient = System.Drawing.Color.White;

dev.RenderState.SourceBlend = Blend.SourceAlpha;

dev.RenderState.DestinationBlend = Blend.InvSourceAlpha;

dev.RenderState.ZBufferWriteEnable = true;

dev.RenderState.AlphaBlendEnable = false;

dev.Lights[0].Type = LightType.Directional;

dev.Lights[0].Diffuse = System.Drawing.Color.White;

dev.Lights[0].Direction = new Vector3(-2.0f, -2.0f, -2.0f);

dev.Lights[0].Enabled = true;

dev.Lights[1].Type = LightType.Directional;

dev.Lights[1].Diffuse = System.Drawing.Color.White;

dev.Lights[1].Direction = new Vector3(2.0f, 2.0f, 2.0f);

dev.Lights[1].Enabled = true;

dev.RenderState.Ambient = System.Drawing.Color.FromArgb(0x202020);

loading of the mesh:

mesh = Mesh.FromFile(filename, MeshFlags.SystemMemory, dev, out materials);

meshMaterials = new Material[materials.Length];

for (int i = 0; i < materials.Length; i++)

{

meshMaterials[i] = materials[i].Material3D;

meshMaterials[i].Ambient = meshMaterials[i].Diffuse;

}

what do i have to do to view my mesh as in the dxviewer?

Light seems to come from the wrong direction, at exactly 45 degrees against the thing in the front. That would make the shading dissapear. Move the light around a bit.

thx!!!
changing the direction of the light makes it much better
it still looks better in the dxviewer but that's not so important
