gl.blendEquation( gl.FUNC_ADD ); gl.blendFunc( gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA );
But using this method i must sorting all objects, to render correctly. Now I'm trying to first render normal objects with depth-testing and without blending. Next render semi-transparent with blending and without depth-testing. That render semi-transparent objects good, but its hidding objects ahead.
