Ah, but it's a post =rendering= process actually, and not really a post process
per se.  Since it is using the scene file info to do it then I can't see why it
wouldn't be legal for IRTC submission.  It's very much the same as any other
in-render effect only done separately, kind of like moving the reflection
raytracing outside of the usual loop and applying it afterward (if that was a
possibility).
That's how I see it anyway.  Well, 'soft_glow'  could very well be illegal since
it doesn't use scene info I suppose.  If anything I believe Nathan Kopp will
have to be the ultimate judge on this by giving an account as to what is done in
a raytrace/rendering sort of way or not.  Same about the proposed lens flare
post process and whatever else of future versions that might be done in this
fashion.
Mainly it's probably going to be more a voting issue than anything else, with
points lost on using such a feature.  I don't think that should be so if a
permission is passed on it for example.

| From the IRTC Stills FAQ:
| [1.1.10] My renderer can do lens flare, motion blur, etc.--is that legal?
|      Yes, generally. If it is something that the renderer does as part of
| producing the image, and not something you run against the image file as a
| separate process, then it is legal. The judges look very closely at such
| effects, however, so use them with caution.
| [1.1.11] Exactly what do you mean by "post-processing"?
|      That means running any image-manipulation program on the image after it
| is rendered. Paint programs, photo manipulation programs, and the like are
| generally not allowed, except for a few explicit exceptions. We want the
| image to be the output of a renderer, not a human or special-effects
| program. One guideline that has been mentioned is that any process which
| affects every pixel in the image is usually okay, but that's not a hard and
| fast rule--it's just used to encompass gamma correction, resizing,
| conversion to JPEG format, and so forth, all of which are legal. Another
| guideline is, don't do anything to the image that you wouldn't be prepared
| to do for every frame of a 30-minute animation.
|
| Since the post-processing is done after the rendering, but it is done by the
| renderer, it would appear that this issue is up to the IRTC Admins.
