Since upgrading to 2.6 (and now 2.6.1), I’ve noticed a very strange issue. Detail meshes appear to be not only influenced by wind, but very strongly so - my bushes are now dancing around the terrain, as if the pivot were 50 meters under it.
Doesn’t happen with grass, only detail meshes. And I’ve checked that it is the wind, because they stand still if I set bending to 0.
Anyone know what’s going on there?
looks like I need to illustrate. Here’s two screenshots. The only thing changed inbetween is some passing of time. The movement of the bush you see is entirely due to wind.
These are bush models from the Terrain Assets download, so I assume that the models themselves are set up correctly. Besides, they worked just fine in 2.5
I have seen this also.
I think if you edit the detail mesh via [Edit Details > Add Detail Mesh-or-Edit] and change “Render Mode” to “Vertex Lit”, instead of “grass” that should do the trick.
It solves the movement problem, but now the bushes look like this:
I am not sure what is going on, but I see what you mean.
If you set any of the “bushes” to vertex lit they turn into sprites or whatever that is. BUT if you use “Rocks” from the Terrain assets package and change those to Vertex lit, everything is fine.
I will run some more tests, but I cant see any difference between the two meshes yet.
any luck in resolving this issue? we have a large amount of understory vegetation to put into an environment and I’ve been forced to implement the simple meshes as trees because of this issue with detail meshes. We also need alpha for the plants so vertex lit render mode is out.
Have you submitted a bug on this? I may if you don’t as I’d like to hear some Unity input on the matter. I don’t think there is anything wrong with my assets, especially since your assets worked in 2.5 and don’t now.
No, I’ve not submitted a bug report. Never thought of doing that for non-crash-bugs.
ok, we submitted a bug for this with a repro scene.
bug id#: 328931
hopefully we’ll hear some good news on how to resolve this.
Has there been any word from the Unity team on this issue?!
We are having the same issues. Is there a fix for this anyone knows of?
Aside of writting an own terrain shader only the “design with it in mind” fix or wait and plan with Unity 3
This appears to still happen in Unity 3.4.1. Detail meshes like the bushes in the Terrain Assets package float around on the terrain, unattached to the ground. Has there been any response from the Unity team on this? Seems odd that no one else is using terrain details.
Can anyone else confirm that this is still a bug, and I’m not just doing it wrong? I can’t be the only person who’s ever used Terrain details in Unity.
I’ve got the same bug in Unity 3.4.1.
Do you know any ways to work it around?
Hopefully will be fixed in Unity 3.5
