CMRT Pz.IV spotting insanity

[A Canadian Cat]

My experinece is that it happens in 'sticky' situations where the LOS is hard to compute. Like in your example, there is a tree near by, but the turret may look by it. City areas and woods, with many terrain objects tend to produce these errors.
That seems to be hard to compute for the game engine.

Workaround:
I developed a 'feel' for these situations over many hours played. So when I am in doubt about what the LOS-tool tells me, I cancel the movement-order and place it again.
This often helps and keeps consequences to a minimum.

An excellent workaround - the issue is that the LOS tool is a from the way point to the ground at the centre of the target location.  But once the moving vehicle is there and the enemy vehicles move around they calculate their LOS and LOF from where they actually are.  Honestly for better or worse the LOS tool give you a feel for what you can see but your gut instinct will get better.  But either way your enemy will be trying to ruin your day and you will lose even when you are careful.  Remember your enemy is trying to KO your stuff so no amount of perfect play on your part is going to prevent that.

The spotting issues are a different story. Spotting is a real weak spot of the Combat Mission-Series.
Can't help there, but I heard from somebody else here on the forum that they are the worst with CMRT and that other titels are less affected. Let's hope for Patches. ;)

Sigh.  That is certainly *not* true.  CMRT is using the same engine as all the others (a few bug fixes ahead of CMBN annd CMFI and a few behind CMBS - non of which I am aware of that will make even trivial differences wrt spotting - unless the hull down spotting bug is one of them but that only applies to a specific situation).  The bottom line is "spotting that is not perfect" is the intended behaviour of the game and is what it is.
