Glare effect in post?

[Lanevo]

Hey!

 

I am wondering if you can open already rendered image in Max and just add the glare effect (without having to render the whole thing again)?

 

The reason I ask is because glare appears to be added after the render is complete, so I am assuming it's calculated in post anyway?

That's going to depend on whether the glare effect is based on scene information such as depth buffer, material id, luminence (or one of those light words), object id etc. or if it's just some brute "blur the white stuff".

I am using the default camera output shader (glare).

 

But I am having some problems with it. For example, if I only render a region of my camera view the glare works perfectly fine. But if I try to render the whole view, glare is extremely strong - basically the whole render becomes completely white.
