When making a new layout in TRS 2012 I notice that a good half of the trees look terrible, no leaves, and some look like they are dead, even when if you go into one of the prepacked layouts, all the same trees look quite healthy and normal. Why is this? I thought that by selecting my region when starting in 'creat new layout' like Australia, United Kingdom, United States etc, instead of just using 'default' that would fix the problem, but no1... I still get tress that have no leaves and look like they are dead...What have I not done?...or what do I need to do to cirrect this?
