In our AvA terrains, we don't number base 1 as Bish, base 2 a Knit and base 3 as Rook. It's always worked but the question was raised. Are we doing it wrong? Especially for someone building an MA terrain?
CraterMA has fields 1, 2 and 3 set to each country and it was accepted by HTC like that. I am wondering now why would this be an issue?
BTW Chilli if it helps this list of objects and groups is what I believe can be put in an alpha MA terrain:
This first lot are all set to group master. The number in the middle of the object name relates to the size of the field, so laf1m00 is 1 mile square and laf4m00 is 4 miles square.
saf1m00         small airfield
maf1m00        medium airfield
laf1m00          large airfield
laf4m00          new very large airfield with built-in town
vb1m00          V field
vb2m00          new large V field that blends to underlying terrain (good for sand or snow areas etc.)
town1m         town for 1 mile square airfields
ttown2m00    tank town
aafac1m00     AA factory
city4m00       city
hq1m00         HQ
amfact1m00  ammo factory
rdfct1m00     radar factory
ref2m00        refinery
trptrn1m00    troop training
bah0             shore battery  (set to hard gun bat)
entpnt          spawn point    (set to veh ent or boat ent)
mpr0            maproom for CV capture (set to map room)
Unless I'm missing something I can't see a way to add CV groups in the alpha TE yet. Possibly this will be added when the supply convoy groups go in.
