Hi everybody, i've got a problem doing alphablending when using texture's alpha channel. The renderstate is:
GraphicEngine.Instance.RenderingDevice.RenderState.AlphaBlendEnable = true;

GraphicEngine.Instance.RenderingDevice.SetTexture(0, Texture.Data);

GraphicEngine.Instance.RenderingDevice.TextureState[0].ColorOperation = TextureOperation.SelectArg1;
GraphicEngine.Instance.RenderingDevice.TextureState[0].ColorArgument1 = TextureArgument.TextureColor;
GraphicEngine.Instance.RenderingDevice.TextureState[0].ColorArgument2 = TextureArgument.Diffuse;

GraphicEngine.Instance.RenderingDevice.TextureState[0].AlphaOperation = TextureOperation.SelectArg1;
GraphicEngine.Instance.RenderingDevice.TextureState[0].AlphaArgument1 = TextureArgument.TextureColor;
GraphicEngine.Instance.RenderingDevice.TextureState[0].AlphaArgument2 = TextureArgument.Diffuse;

GraphicEngine.Instance.RenderingDevice.RenderState.AlphaSourceBlend = Blend.SourceAlpha;
GraphicEngine.Instance.RenderingDevice.RenderState.AlphaDestinationBlend = Blend.InvSourceAlpha;
GraphicEngine.Instance.RenderingDevice.RenderState.AlphaBlendOperation = BlendOperation.Add;


I'm using it on a TransformedTextured Vertex type. The code that loads the picture (DDS format, DX Texture tool shows that there is an alpha channel in the picture):
TextureAtLevel0.Data = TextureLoader.FromFile(GraphicEngine.Instance.RenderingDevice, FileName, 0, 0, 0, Usage.None, Format.Unknown, Pool.Managed, Filter.None, Filter.None, 0, ref Info);


The texture shows like there wasn't any alpha channel : an example picture can be found here: The original picture can be found here: PNG Version DDS Version Can somebody help me? [edit] forgot a line in Texture State [Edited by - PERECil on August 24, 2005 8:31:04 AM]

Oh! Thanks! The problem has gone away :). Mmm I should program a tool that would permit me to change on the fly such things to test differents combinations. This would help me a lot I think :).
