   global transparency... is possible?
  Let''s say i want display 3 faces (that''s 9 vertices in buffer)with same transparency value. Is possible to set transparency value as "global"... or is this only possible by setting DIFFUSE alpha value in every vertex in vertexbuffer? 
  You can put the constant alpha value into D3DRS_TEXTUREFACTOR then tell D3D to use that for alpha in your SetTextureStageState() calls (D3DTSS_ALPHAARGn = D3DTA_TFACTOR)   --Simon O''Connorex  -Creative AsylumProgrammer &Microsoft MVP
