Crashing when placing trees

[epsilonion]

After a short while of placing the OAK tree that comes with the engine it crashes, easy to repeat, just place trees, well tbh you don't have to place trees it just crashes...

The Idea I had was camera fly through of a river surrounded by thick forest, at the end of the river the camera circles your farm, although a small farm, I was going to narrate this.

The picture shows the patch to Skyline.

Q) What is the ram used by skyline at the time of the crash?
it seems you had too many trees at high poly lol and hit the 32bit application limit.
This will require a 64bit machine to run that tree many times over.
64bit is being done on the side of all the other tasks.
With skyline, once you get to around 3gig of ram used, then look at saving your scene as a crash could be imminent.

The oak tree has something like 3000 polys+

Static Batching is a fast system which improves performance to no end, but you have to pay for each mesh that is added to the scene rather than add one and reuse that asset like the normal drag mesh. This is why the vegetation system prefers to have lower poly objects for memory/performance reasons.

The oak tree was a stand in mesh asset that i used without the vegetation system for the melee template.
Plus i wouldn't place a lot of them as they are quite pricey to add into the scene.
