I''m loading a .tga file and have loaded in the GL_RGBA format. I want to use the alpha value for alpa blending. I had it working for a second then I don''t have a clue what happened and it stopped. Does anyone have any ideas?

you can use the glBlendFunc to set pixel arithmetic,use the glAlphaFunc to set alpha test,and use glEnable(GL_BLEND)to enable alpha blending.the particular ways please see the OpenGl function reference.
