I posted this on the scenery site but so far there have no takers. I would like to try some simple airport upgrading, such as adding taxi signs, buildings and maybe after practice animation. My question for those that know is what programs are available to do this this. I 'm am not opposed to payware because I need something that has a db of structures or signs.Thanks in advance.

Also check out www.taxiwaysigns.comThey don't have every airport, but have many of the major ones in the US at least. I LOVE them and they don't seem to have much/any affect on framerates.
