Hiya. Why isn't my water transparent? Sorry, the more I read about alpha blending on the web the confuseder I get. Basically I am enabling alpha blending/testing, then creating a water color in the pixel shader, and setting the alpha channel of my water color to 1 to make it transparent. All of the other settings are strictly by rote...it's what all of the web articles say to do, with none of them giving any clear reason as to WHY. Thanks void DrawWater() { .... GraphicsDevice.RenderState.AlphaBlendEnable = true; GraphicsDevice.RenderState.AlphaTestEnable = true; GraphicsDevice.RenderState.BlendFunction = BlendFunction.Add; GraphicsDevice.RenderState.SourceBlend=Blend.SourceAlpha; GraphicsDevice.RenderState.DestinationBlend=Blend.InverseSourceAlpha; .... } WPixelToFrame WaterPixelShaderFunction(WaterVertexShaderOutput input) : COLOR0 { .... //create a color based on position, reflection, blah blah blah Output.Color = lerp(combinedColor, dullColor, 0.2f); Output.Color.rgb += specular; Output.Color.a=1.0f; return Output; }
