You can reduce the poly count of trees dynamically with the in game tree detail sliders. We already use lower poly count trees away from the lines of play. As a designer you can also raise and lower the individual poly counts of trees within the project.
The PP courses are generally very well optimised but the community courses will be a mixed bag.
Thanks Mike. But does this mean you can select a group of already planted high poly trees (such as the ones off the course of play) and lower their poly count? I would think that would be ideal. Probably a stupid question, and I will stop asking them after I get my copy of CF!
