I don't understand alpha testing apparently!!!

Woo hoo!!! I always thought I did, but now that I''m actually trying to use it I relize I don''t. If someone can help me, this is what''s going on. I''ve made this function that will dig through a texture and replace one specified color with another color you specify. Now, I use TextureColorReplace( graphic_Cursor, D3DCOLOR_ARGB( 256, 0, 0, 0), D3DCOLOR_ARGB( 256, 0, 100, 0) ); I replace all of my opaque black pixels with opaque dark green ones (this is how I know my TextureColorReplace works) Infact, I have succesfully changed colors to colors several times with this function to ashure it works, but the above was an example. The proplem is that if I use TextureColorReplace( graphic_Cursor, D3DCOLOR_ARGB( 256, 0, 0, 0), D3DCOLOR_ARGB( 0, 0, 0, 0) ); I would then, in theory, have replace all of my opaque black with completely transparent black... Hower that is absolutely not what I''m doing (whatever it is that it is doing *shrugs*) I''ve been working on this for a long time and I can only think one thing is to blaim... My renderstates. I''ve changed my renderstates several time (referencing 4 books that I own) and I can not get this to work... here''s what there currently set too g_pDevice->SetRenderState( D3DRS_ALPHABLENDENABLE, true); g_pDevice->SetRenderState( D3DRS_ALPHAREF, 0x01); g_pDevice->SetRenderState( D3DRS_ALPHAFUNC, D3DCMP_GREATEREQUAL); g_pDevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCCOLOR); g_pDevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_INVSRCCOLOR); Needless to say I have no idea what values these should be set too. I''ve tried a lot of different values and nothing is really working. Does anyone know what''s going on here? (if you need/want more information about my code I''d be happy to supply it :/ )

Namethatnobodyelsetook!! Your right! That''s all it was, I had to use the EX load inorder to get the color formated I want, after that it all made sence. Thanks.

Believe it or not, the idiot is learning.
