Hi,

i had a quick question, is it better for game performance to paint grass using the paint details or using paint trees?

I’ve been fiddling around with the terrain tools and i can’t seem to get the paint details to work, i created a PNG of my grass but it isn’t working (its not appearing on my terrain when i select the brushes and paint). Instead, using the whole 3d model and painting the grass on as trees is working for me. But i’m worried about having 50,000 prefabs of grass on my terain might cause performance issues.

Also since im painting them on, does that mean that wind won’t work on it?

if you could link me to a tutorial or article i would be very grateful.

PS. do you know how i can measure the FPS of the game? How do i get it to display? is it through a script or is there a built in way in the editor?

Game window has basic stats view:

Window/Analysis/Profiler will give more details

And Frame Debugger tells more info, like why objects are not batched

Asset store has advanced FPS counters, this is probably best of those:

And for grass/trees/vegetation plugins that are much more performant than anything builtin, some of those:
