Camouflage
One factor when calculating spotting range is the camouflage factor of the vehicle to be spotted. The higher the target's camouflage factor, the shorter the spotting range.Calculating the Camouflage Factor
The camouflage factor is calculated as follows:camoFactor = baseCamo * (0.00375 * camoSkill + 0.5) * camoAtShot + camoPattern + camoNet + environmentCamo
The camoFactor cannot exceed a value of 1, so if the equation results in a higher value camoFactor is set to 1.
Let's look at the different elements of that equation in detail:
- baseCamo
- Every vehicle in game comes with a base camouflage value assigned to it by the developers as part of game balancing. The value is defined separately for moving and for standing still. The baseCamo value is generally lower while moving the hull than while standing still, but for some tanks including most light tanks the values are equal for both states, which is a big advantage for dedicated scout tanks.
The baseCamo values are not shown in game but can be calculated based on the spotting range formula and the formula for the camouflage factor explained here. Allow for a certain margin of error because of differences in the distance display in game and the distance between visibility checkpoints and view range ports plus the fact that in game distance is only shown in 1 meter steps.
- camoSkill
- This is your crew's effective skill level for the Camouflage skill.
- camoAtShot
- This is another value defined by the developers for tank/turret/gun combination individually as part of game balancing. The same gun can have a different value on different tanks (or theoretically even on different turrets on the same tank, although no example is known of that). Gun caliber or existence of a muzzle brake on the gun have no influence on this value.
The value is not displayed in game, but can be determined through testing in the same way as the baseCamo value (see above). The value is on average around 25%.
- camoPattern
- This is the camouflage bonus provided by a camouflage pattern permanently bought for gold or temporarily rented for credits via the "Exterior" window. If a camouflage pattern of the same type as the map you are playing on (summer, winter, desert) is applied. The amount added depends on vehicle type, biggest is for tank destroyers. Since map selection in most game modes is random, for most of your tanks you'll have to buy a camouflage pattern for all three map types if you want to ensure you always get the bonus.
- camoNet
- This is the camouflage bonus provided by Camouflage Net equipment, if installed and active (you must have been standing without moving your hull for at least 3 seconds). It provides a bonus based on vehicle type, biggest is for tank destroyers.
- environmentCamo
Environment Camouflage Schema
As soon as you fire your gun, the camouflage bonus provided by transparent objects in a 15m radius around your tank is reduced to 30% of the original value. Objects furter away are unaffected.
Environment camouflage bonuses stack, but special rules apply when firing your gun:
- In the illustration to the right, each bush provides the same environment camouflage bonus X. Since these bonuses stack, tank 1 has an environmentCamo value of 3 * X.
- However, as soon as tank 1 fires its gun, the environment bonuses within the 15m radius no longer stack. Instead, only the bonus from the bush with the highest camouflage bonus is taken into account. In addition, the bonus from that bush is reduced to 30% of its original value, so 0.3 * X. Bonuses from environment outside of the 15m radius stack as usual. Thus, while firing tank 1 has an environment camouflage bonus of 0.3 * X + X = 1.3 * X.
No camouflage bonus is provided by:
- Player tanks (dead or alive)
- Grass
- Downloadable camouflage skins as opposed to the camouflage patterns you buy for gold or rent for credits
- Anything else
Note that your tank does not need to be fully hidden to take advantage of an environment camouflage bonus, the environment only needs to cover all of your visibility checkpoints in the direction of the spotting tank's view range ports for the bonus to apply.
Examples
Let's look at an example to see how it all comes together.Say our spotting target has a baseCamo coefficient of 25% or 0.25 while standing still and 15% or 0.15 while moving the hull. The camoAtShot factor is 25% or 0.25 as well. The entire crew of 5 has 100% Camouflage skill level and the Commander has 100% primary skill level. Improved Ventilation equipment is installed.
Should this calculation be confusing to you, remember that you need to factor in both the bonus from Improved Ventilation equipment as well as the Commander bonus. It would, however, be understandable if the calculation above still seems confusing, because there's no way to tell what those figures relate to unless you spend some minutes figuring out the equation. To make things easier for you, here's the above numbers explained:
- (CommanderSkill + VentBonus + (CrewSkill + VentBonus + (CommanderSkill + VentBonus) * 0.1) * NumberOfNonCommanderCrewMembers) / TotalNumberOfCrewMembersIncludingCommander = X
- 0.25 * (0.00375 * 113.4 + 0.5) + 0.64 = 0.8713125 (87.13%)
- 0.15 * (0.00375 * 113.4 + 0.5) = 0.1387875 (13.88%)
First example: 400 - (400 - 50) * 0.8713125 = 95.04m spotting range.
Second example: 400 - (400 - 50) * 0.1387875 = 351.42m spotting range.
Tips
- A camoFactor of 1 means your tank is invisible up to 50m to any possible spotter.
- Bushes or standing trees within the 15m diameter become transparent to your view. This helps you determine your distance from them.
- To maximize your use of camouflage bonus provided by your environment, do not sit inside of bushes while you fire, instead sit more than 15m behind one or even several bushes. This is particularly important for scouts. Firing reveals your position. If you absolutely need to take a shot, e.g. to track your target for your team's artillery, pull back just before you take the shot - your target will stay visible to you even with the bush intransparent for the normal spotting duration. However, don't forget that enemies can see your tracers, so you may see shells homing in on your position despite being invisible to the enemy.
- Since dedicated scout tanks have the same high base camouflage values while standing still as they do while moving, they are best for reaching forward spotting positions unseen.
- Baiting the enemy to shoot you can be an effective tactic to light them up because of the camouflage reduction while shooting.
- As long as you are outside of 445m maximum spotting range you do not need to worry about camouflage, you will be invisible to the enemy team regardless of what you do. The difficulty is knowing whether you are outside of their maximum spotting range - keep paying attention to the minimap as enemy tanks get spotted and memorize their locations/count.
