Posters have less effects?
Hey there,

I was just exporting some posters of my new little movie to show my friends when i realised that the exported images didnt seem to have as much detail as the image in the viewport.

Here's an image i exported as seen in the viewport:,htKvnt2#1

And here's the actual exported poster:,htKvnt2#0

The one in the viewport seems to have much more lighting effects than the exported image.

Anyone know what's happening?

Hm, well I know bloom and material overlays don't appear in poster, but that looks like either a volumetric light or a corona (my money's on corona since you don't mention any volumetrics), but as far as I know these effects work in posters... I'm a test a thing or two...

One of the coronas didn't appear, while the other is weaker than it should be. Yup. Coronas are broken in posters too.

what are coronas?

It's more or less a sprite that simulates the intense bloom of a bright light source. There's one in just about every shell lamp and spotlight in TF2.

I believe they prefer to call them flares in Source, not sure about that though. In fact I'm not even completely sure I'm not mistaken in calling them coronas ;P

is it any automatic thing, or a particle effect, or what?

Can't say i've every come across it before outside of lens flare people have added in post.

It's a map thing, as far as I know there's no way to control them in SFM directly. The env_lightglow entity is one way to do it:

Oh ok.

Make sure you are not overriding your actual camera settings within the animation sets (Depth of Field, Motion blur) with override settings in your export options... that will cause it to look different from what you have in the viewport.

Another thing to consider..try rendering a movie image sequence instead of a poster.. then pull your still from the sequence. Like R234 pointed out, certain things don't work when exporting posters for some reason. You can opt to only render a very small sequence so you only are rendering the portion you want to create the poster from.

By the way... what are your camera/render settings anyway? As in.. Depth of Field, motion blur, etc. We are beginning to discover that high DoF settings can cause particle systems to not draw correctly during the render. For instance, at 256 DoF samples my smoke_cloud particle systems are completely see through and they certainly don't look like that in SFM's viewport. When i lower the DoF samples to 128 it gets a little better, but still not quite what they look like in my viewport. So anyway I wouldn't be surprised if high DoF was messing with other things like lighting in addition to particle systems.

Rendering a sequence allows you to choose from multiple shots of the same scene to get that "just right" one you're looking for as volumerics do change over time and do some of the other features that can't be set in a poster render..

ahh right ok thanks for the replies! I wasn concerned that i was doing something wrong, but if it's like this for everyone, im not going to worry :)

Thanks again

If I may, I'd suggest increasing the DoF samples in render settings to at the very least 64. 8 doesn't look good at all, especially in a poster ;P
