tree system popping

I’m experiencing a couple of issues with the terrain editor tree system:

  1. When I rotate the camera up and down (to look up into the sky) , the billboarded trees in the distance float off the ground. If the camera is level, the trees do not float. This only happens when the trees are billboarded with the new terrain system. The trees are pretty tall, between 20-40 meters. Is there anything I can do to stop the floating besides turning the billboarding off? It also happens if the camera is looking down at the ground, not just when it looks up towards the sky.

  2. I’m also getting a weird popping issue that I’m not sure now to word correctly. The trees don’t pop when switching from mesh to billboard, but when transitioning from being off screen to on screen. If I look up into the sky, and then rotate the camera down, the trees pop into frame a little too late. It seems like they’re being drawn too late? Is there anything I can do about it? I thought maybe that trees that are offscreen are being culled, and when the camera pans to where they need to be brought back into view, then they are being brought back on screen a little late…or something like that.

I hope this makes sense.

Thanks in advance…

Increase the billboard distance in the terrain settings

maybe I didn’t explain correctly…did you mean the billboard start, or the tree distance setting?

My tree distance setting is plenty high enough( it’s bigger than the entire terrain)

I know if I raise the billboard start setting up higher than the distance the trees are away from the camera, that it takes care of the floating trees, but it also won’t be billboarding them anymore. I want to know if there is an alternative or not so that I can still have the billboarding start at 50, but not have trees that are 300 meters away floating off the ground?

I figured out the answer to my second question, but I’m not sure if this is a bug or not.

It appears that when I’m painting trees and set the tree height to greater than 100 percent in the tree brush settings those are the ones that pop in and out of frame. It’s hard to explain, but it only occurs on trees that have been painted at greater than 100 percent. I can get around it by importing my mesh at a larger scale, and always painting smaller, but I wasn’t sure if the unity guys were aware of this issue?

If anyone wants to see the issue I’m talking about, I could post a couple of screenshots later…

EDIT:

It only pops in and out when viewing the top of the tree and looking up at it. It’s like unity thinks the mesh is still at 100 percent, even though it displays at the painted height of 150 percent.

I’d appreciate it if you can make a small sample project that shows the issue and send it in via Report Bug.app

Okay,

I submitted the bug report…

Thank you very much
