Dust seen beyond visibility limit ?


Tero

Recommended Posts

Just noticed in PBEM set in dusk visibility constrains you can see dust clouds kicked up by moving vehicles beyond the prevailing visibility limit.

Has this been discussed in detail ?

If so, directions would be appreciated.

I think this goes under the heading of a feature that cannot be comprehensively supported by the existing game engine. They really wanted to include the dust clouds, and mostly they are a boon, so I reckon the decision was justified, but some of the details don't work right. I'd be surprised if this wasn't noted during beta testing and the decision was to go ahead with it anyway.

Maybe if you think of it like this it may help make sense.

There is a reduction in visibility as night falls (and an increase as it ends) such that it becomes more and more difficult to make out men and vehicles on the ground than it would during full daylight hours where you could see things many hundreds of metres away. So visibility of units is restricted during these times.

But I find that the sky stays brighter than the ground at these times so it would stand to reason that any dust clouds (which rise up into the sky) will be visible from distances greater than that of the visibility of units on the ground.

How does that now grab you as a game feature?

I can live with this engine compromise. Of course we can all imagine circumstances in which it would be absurd (a foggy night on a 6km x 4km map), but those will be very rare.

In general, dust is a factor only in dry conditions, and dry conditions occur mostly with the clear weather that makes Andrew Kulin's explanation more than plausible.

What about night battles ? I assume the feature is present even then. If not then it all is pretty much OK.

In general I am would agree with him and you.

But even given that the fact the clouds reach all the way to the ground which make me think it as more of an excuse than a fully fledged explanation. The dusk and dawn are a bit vague when it comes to defining it in the game. smile.gif

Lazy sod. It's:

Designer’s Note: Dust is always seen anywhere on the map - with or

without LOS to the unit(s) causing it - during dawn, dusk, and mid-day

light conditions, and is never seen (even if it should be kicked up in

theory) during night conditions. This is a necessary engine abstraction

to prevent unrealistic spotting distances during the night.

There's a note on page 62 of the CMAK manual that answers your question. The upshot is that there's no dust at night.

I'm too lazy to copy the relevant passage, however. smile.gif

And I am too lazy to open the PDF file. ;)

Bring back the proper manuals, damn it !

That is the thing that irritates me. I just have to force myself to ignore it, despite the strange effect of being able to see a dust cloud progressing along the opposite side of a tall ridge from where my men are all tucked in...

GaJ.

I always just assumed the dust was a fairly tallish plume, so my guys would have no trouble seeing it rise above the ridgeline. Like, if the plume is 100 meters high, the ridgeline isn;t going to totally block LOS to the cloud.

True. But the way it s modelled now the plume is at 100m instantly, as it were. And you can always pinpoint the exact location of the vehicle making it.

It is not uncommon to have troops on the south side of a ridge (reverse slope defense) seeing the progress of (the dust of) AFVs travel along the north side of another ridge 1km to the north. The troops in question can't even see the second ridge, let alone (dust from) the AFVs behind it.

It means that those defending troops have time to adjust to the direction from which the impending threat is coming...
