Large land with great vegetation Editor Lag

I have a big project, I want to make a survival game. For that I bought some help assets and one of them was GAIA for terrain creation. GAIA works very well, however with a very large terrain some problems happen.

All LODS are working correctly, I researched a lot and saw many talking about terrain stream, but it is very bad to work with terrain stream, is there any other way to work with giant scenes in unity3d without breaking them in several scenes?

 

Are the LODS for terrain or just vegetation? Unity's default LODS can provide horrible performance. If you have tons of vegetation, then that might be the issue and not the actual terrain. Unless the terrain has some exceedingly mega amount of vertices, then that probably isn't the issue.

(I am unfamiliar with GAIA) Are you just rendering terrain? Is there vegetation/trees (if so, how much)? What is your batch count and vert count? Is the terrain a single mesh or is it broken up by cells into smaller meshes for LOD purposes?

 

Nature renderer solves most issues with vegetation performance:

works like a charm for everything we have thrown at it

 

I have a plot of 10km cut in 4x4 with vegetation in all

 

interesting, do you know if it is easy to use with gaia? and also what is the biggest terrain it supports?

 

Yes, you can use Nature Renderer with Gaia, but you need to be careful with it. By default, some of the Gaia runtime code will enable and disable terrain and vegetation stuff as it goes in and out of view. When the Gaia runtime does that, it can turn on both Unity vegetation and Nature Renderer vegetation rendering at the same time, and that can cause performance to get even worse. Gaia does not detect Nature Renderer. You will need to manually edit at least one of the Gaia runtime scripts to prevent the issue if you plan to use Nature Renderer.

 

Yes all true. It works great with Gaia and can take you from < 30fps to >60FPS with almost no work - but the interactions between the 2 assets need to be monitored closely and a couple of changes here and there made to make them work flawlessly. Very much worthit IMO

 

Hi there,

Shameless plug, but I have a new product coming to the Asset Store that is designed around reducing the pain points related to streaming. It's called S.A.M. - The Streamable Assets Manager and should be available this week or next.

You can read more about it here. There is also a promo video for it available on YouTube.

If you are looking to split up your big terrain into smaller slices, you can check out my other product, Terra Slicer, which will also be available this week or next. More info can be found here.

I don't want to flood this thread with anything else, so if you are interested, feel free to post in the threads in those links, or PM me if you have any questions.

 

I really liked it, I'll keep an eye out when it launches!

 

Do you have a discord channel?

 

Yes we do!
