Blending not working?

Posted Saturday, 1 December, 2012 - 03:08 by Ichiru in

Hello all!
I have 2 quads with pngs as textures rendered on top of each other
I enabled blending and set the Blend Function through GL.BlendFunc (BlendingFactorSrc.One, BlendingFactorDest.OneMinusSrcAlpha);
However, when it is rendered, the textures only blend with the background color? GL.ClearColor(Color4.White);

Can someone please help me with this?

Does the second texture actually have an alpha channel? Draw with another ClearColor, like Color.MidnightBlue.
