For those interested,I have been trying to load the bombs in the weapons drop down in FMB onto the bomb towing trailers.
It took me a while before I worked it out how to do this.
If you just place the bomb onto the trailer the bomb will lie beneath the trailer,no good,if you type in 0.3 into the 'zoffset' box which is within the bomb parameters,this will place the bomb correctly onto the trailer rack.
There you go another bit of useless info,hope this helps,and it will save time,if you like me like building your own missions within the Full Mission Builder.
I am learning as I go,this is probably common knowledge to the more dedicated simmers amongst you.
