I'm not sure how this works, because all the examples talk about drawing your entire LOF through a Low-Vis zone, or into a Low-Vis zone. So, if I have a model (Model A), and they are shooting an opponents model (Model B), and can draw a line of fire past a low-vis zone, but not entirely - the majority of their line of sight to the other model is obscured by the zone - will they suffer the penalties of the low-vis zone? I've attached an example to make it clearer. The blue line shows that A has a line that doesn't go through the Low-Vis Zone to B, but the red line shows that its LOF definitely goes "through" the Low-Vis. It's a situation that hasn't come up with my local group before - Nimbus are quite rare, and people tend to throw them directly on their own models, or a target enemy model, so I've not had to wonder about this situation before, and the rules aren't super clear - they use words like "Through" but don't give any examples of if its partially through, or strictly totally through. Cheers in advance.
You only get (partial) cover if you in base contact with scenery trust covers one third of your silhouette. If the silhouette touches smoke the whole model counts as being inside the smoke, if it doesn't touch the smoke it is not. That's why the models on your picture doesn't get any cover due to low vis zone. If you can't draw LoF due to physical objects then you have total cover. If you can't draw LoF due to low vis then you can respond only if some other model can affect you.
You can draw LoF from any point of your silhouette to any 3x3mm part of your opponent's silhouette. In you example you could choose to draw LoF along the blue line avoiding the Low Vis Zone.
Cover isn't really relevant - you don't get cover from a Low-Vis zone provided by a Nimbus grenade ever, so it's not really a factor. Your second sentence is also incorrect - models can see through Low-Vis, that's why its "Low" instead of "Zero", so you can both fire through it and respond at all times (provided your facing is correct, obviously), you simply suffer a -3 penalty (and -1 burst if its also a saturation zone).
Yeah, I thought that's how it worked - same as skirting a Zero-Vis or obstruction - but the examples weren't comprehensive enough, since they only cover shooting into / out of it. Got some new players who are keen on the Shikami, so wanted to make sure it was played clean (and none of my own factions have access to Nimbus).
Yea I read it wrong. I responded to the partial part and thought you meant zero vis and partial cover since that's where partial is. My mistake.
All good, just wanted to make sure that anyone in future who has the same question and finds this thread isn't confused.
I'm a little unclear on that based on: Area of Effect of Special Terrain Zones The Area of Effect of a Special Terrain zone is the area in where its special effects are applied. Any trooper in base contact with a Special Terrain zone, or whose base or Silhouette Template is covered at least partially by Special Terrain zone, is equally affected by the Effects of the zone. Is the model's silhouette not partial covered by the zone? If it was just based contact I agree it would not effect the model in the diagram but what does it mean by "Silhouette Template is covered at least partially"? I'm fairly new to the game so trying to work out the different meanings going on here.
Partially covered requires physical contact the fact that the cover intrudes partially into the line of sight is irrelevant for Infinity. Due to the assumptions about the dynamic nature of movement in the game cover is ineffective unless your actually hugging it. Robert And IJW beat me to it
I get that part, just trying to understand how the silhouette being partially covered is different from base contact. If it just wanted based contact with the zone why mention the silhouette at all then?
I imagine it would take care of effects that start on an elevated surface. If you are on the ground, then you aren't technically in b2b contact with the zone, but your silhouette is in contact with the zone (i.e. partially covered by it). Or perhaps if you have a zone next to, but not touching, a ladder. As your trooper climbs the ladder, they move with their base flat against the ladder itself, so your silhouette protrudes into the zone, thus being partially covered by it.
Looking at it from the top down, your circular template of a smoke (of any kind) could affect a trooper by 1) totally covering it's base, 2) partially covering it's base, or 3) not covering the base, but simply touching it (base contact only). If you have the slightest mm of separation, the effect is not applied.
