How many unique trees per map is it safe to use?
Though the number of trees can be relatively great, the number of unique trees should be controlled. The engine spends a fair amount of time calculating each unique tree so limiting the number is a good idea to keep your map running smoothly. At present it is recommended not to have more then five unique trees per map. Please note the same tree with two different seed values is considered two unique trees. But tree scaling is not considered a unique tree so using the same tree/seed value with different scales is an easy way to add variety. In short – too many trees with diffrent seednumber is a bad idea.
