HowTo/Scenery/mesh-table/fontsize
From TrainzOnline
fontsize
This tag is compulsory when creating a "kind" "name" effect.
Data type for this field is a floating number i.e. 1.0.
It is the size of the font as it is displayed in trainz. Now sizing is a bit of a mystery because it not like the size in a word document. A good value to start with is 0.15. Once you have your asset in Trainz then you can go back to your config file and adjust the value you have used.
