Summary0004946: Candle Flame Particle Behind Wall Shows in a Mirror
DescriptionIn Night of Reluctant Benefaction, there is a mirror in one room and a stock candle in the room behind it. Under certain viewing angles, you can see the candle flame particle show up in the mirror but not the candle (or light emitted) itself.

The two rooms have proper visportalling, so the visleafs should be sealed from each other. Extinguishing the candle in the other room makes the particle go away from the mirror. Relighting it brings it back.
Steps To Reproducehttp://forums.thedarkmod.com/topic/19774-beta-testing-207/page-7#entry432487

This post contains screenshots. In anorb2.map, the getviewpos is "635.64 535.45 300.25 2.4 -84.2 0.0"
Additional InformationThere is an additional candle in the room with the mirror. It does not affect the reflection from where it is, but if you bring it to the other room and place it next to the offending candle, you may see two candle flames in the mirror depending on your position.

AFAIK The particle gets to the screen because the mirror clip is a part of the depth test and the particle does not write to depth buffer.

I would propose to pass the mirror clip plane to soft_particle.vfp but since the ARB2 shaders are scheduled to drop in 2.08 it has to wait until then.

I don't think anything has to be done on the portal code or the map.

Soft particles is new feature?
Is it possible to disable it? If yes, then how?
If they are disabled, then the problem disappears?
