there is a way but when it comes to terrain lightmaps there is a bit of a problem with the shadow of the ship on the water.HughJass wrote:To rhino, this version is just a placeholder version, the final version will only have PLANM(assaulting) vs USMC(defending), unless we can figure out a way to get both versions in by using layers.
Its possible to have both ships LMed (as in the objects themselves) and only applied when that ship is in the map, you could also force each ship onto there own lightmap atlas (or get both of them to use the same one) but ye, the terrain shadows is a bit of a show stopper, I can't think of any way to force a swap of a terrain LM patch between layers...
EDIT: thou I have just thought of an idea but its a pretty big hack and not 100% sure how well it would work hehe.
Basic idea is that you do not cast the ship shadows onto the terrain. Instead what you do is you cast them onto a waterplane (a staticobject bit of water) and you put that waterplane just over the water that you only have loading in that layer with that ship.
The problem here is that you will need to try and avoid any zfighting that might happen and you also need to make it look like there is just one bit of ocean there and no waterplane above.
Much like this quick max scene here:
