I am trying to blend textures which have transparent areas:
glEnable( GL_TEXTURE_2D );
glBindTexture( GL_TEXTURE_2D, ...);
glVertexPointer( 2, GL_FLOAT, 0, ... );
glEnable (GL_BLEND);
glBlendFunc (GL_ONE, GL_ONE_MINUS_SRC_ALPHA);
glDrawArrays( GL_TRIANGLE_STRIP, 0, 4 );
Unless I add glDisable(GL_DEPTH_TEST), transparent parts of the top textures overwrite everything beneath them (instead of blending). Is there any way to do this without disabling depth? I have tried various blending functions but none of the helped.
