Now after flying through this a few times I realized this could be used in the MA to limit field shutdowns and vulchers. The smoke quickly builds and blocks other building & uppers from view.
The changes you made in AH would certainly do that, but your own photo shows that real smoke from real fires do not do that. The gases coming off fires, which are carrying the smoke particles, are very hot and therefore they tend to rise straight up due to buoyancy, i.e. they are hot and therefore much less dense than the surrounding air and tend to shoot straight up and do not spread radially very much. As your photo shows the smoke plume diameter is not much larger than the fire itself until the plume rises quite a bit and cools off, reducing buoyancy effects. If AH smoke were more realistic, i.e. it spread initially much less than is currently modelled, then the fields would, at lower alts, be even less obscured than now (and, coincidentally the frame rates would be less adversely affected since fewer smoke textures would be rendered).
