c# - SharpDX Pixel shaders need different parameters for different SpriteBatches vs DrawQuad. Fixable? -

i'm new building graphics engines , kinda stumped on particular issue.

i have issue getting pixel shaders work using same set of parameters both. causing me have create 2 different techniques each method. if try use same parameters both, 1 of them return nothing.

my goal use 1 set of parameters shader, eliminating sprite specific version of each technique use.

here have do:

hlsl pixel shader

texture2d texture : register(t0); samplerstate texturesampler : register(s0); texture2d texturealpha;  cbuffer projectionmatrix : register(b0) {     row_major float4x4 matrixtransform : packoffset(c0); };  void vs(     inout float4 color    : color0,     inout float2 texcoord : texcoord0,     inout float4 position : sv_position) {     position = mul(position, matrixtransform); }  //method required using drawquad float4 ps(     float2 tex : texcoord0     ) : sv_target {     float3 tcolor = texture.sample(texturesampler, tex).rgb * texturealpha.sample(texturesampler, tex).a;     float alpha = texturealpha.sample(texturesampler, tex).a * texture.sample(texturesampler, tex);      return float4(tcolor, alpha); }  //method required using in spritebatches float4 pssprite(     float4 color    : color0,     float2 tex : texcoord0     ) : sv_target {     return ps(tex); }  technique masksprite {     pass     {         profile = 9.3;         //sprite's require vs set well.         vertexshader = compile vs_4_0_level_9_1 vs();         pixelshader = compile ps_4_0_level_9_1 pssprite();     } }  technique mask {     pass     {         profile = 9.3;         pixelshader = compile ps_4_0_level_9_1 ps();     } } 

loadcontent() code

spritebatch code
