I'm working for a post-processing effect for a long time.
I use multi rendertarget to achieve this effect.
But I met a problem.
As the screen shot show,I rendered object two times, one with glow effect and one not, they are in same position,But the glow effect is just a 2D image.So the effect become unreal,just like a 2D image cover in a 3D scene.
I want this effect looked like a 3D effect.
How do I fixed it?
