I like using void chest from railcraft, it's way better then void tubes or throwing trash into the lava, but there's one annoyng thing, is that in any room i placed void chest it sometimes randomly makes black particles.

Example:

Is there any option to disable this particles? and if not, i suggest you to add it, i'm currently in the middle of, use comfortable void chest and tolerate this particles, or make a void tube, which is worse but at least no particles

Right. Void chest particles should spawn in a relatively smaller range and with higher precision

I looked at that code the other day... it seemed... odd somehow. The way it picks a random block and generates particles on its face.
