Is there way to clear a scene with a transparency (alpha) value, in pure SFML?

I'm trying to clear with rgba(0,0,0,128) so the previous frame still partially shows through, which would create a motion blur effect.

I tried window->clear(Color(0,0,0,128)); but with no result


"Clearing the scene" will not produce this motion blur, you want to draw your frames into a RenderTexture, then draw this texture onto the main screen with your Alpha Blending enabled. Never clear the screen except on window resize.
