[WIP] Leaf System Pro

Leaf System Pro is a scriptable "Smarticle" system which generates, maintains and emulates the effect of leaves blowing in your scene. I started working on this system over a year ago and just let it sit for the last 9 months. Now I have revived it, and improved it and aimed my sights at Gaia with it.​

​

The Features
1) Custom physics simulation
2) PBR Dual sided leaves
3) Frustum view based Occlusion Culling
4) Custom Object Pooling system
5) Run hundreds of leaves/debris in your scene with little to no performance impact
6) Integrated sounds
7) Zone based
8) Works with Zone Controller
9) Designed for Gaia

Here is quick demo video with Gaia

Here is how you can set it up in Gaia:

I will be launching a closed beta for those who would wish to participate...please contact me.

 

Hope you release it soon. Or we can test it out to see if there are bugs in it.

 

I will start beta testing soon, please send me a PM and I will discuss it with you.

 

The beta is almost ready:
Here is a new video...

 

Hi John
Is it possible that the zones recognize what kind of tree variety is near, to spread the fitting leafs for the trees, so if there is a birch, there are birch leaves, for a oak tree...

Cheers
Michael

 

This looks fantastic. I am pretty sure this asset will give terrains more realism. Good job!
I did not wath the second video but do leaves also fly aways or move a little if the character is near? So not only the wind does make them fly aways, also the player movement?

Does your asset also work with Scion and SSAA Posteffects?

 

I'm working on that today

 

For the sake of the video, I setup zone triggers that would activate the WindZone in the scene...That is why is seems like its's player driven.

This video is show with Scion and SSAO Pro, and post processing is a non issue.

Thanks,
john

 

Here are some screenshots of the UI:

This script stack lives at the top of the chain and controls the overall scene level simulation.
Wind Volume will control the sound of wind gusts when the velocity of the wind changes.
The Master Mixer will allow you to fine tune adjust performance settings.

 

This is a Leaf Zone controller, which specifies a region of the map that controls the lifespan of a group of leaves.

 

This script allows you to attach to a Unity WindZone as a source of Wind Velocity and Direction

 

In each Leaf Zone, an emitter is responsible for managing the pool and instantiating various leaves

 

You can specify per zone what you want the Wind Settings to be applied at

 

Here are the properties of each individual leaf instance

 

This is finished, btw

 

I have the beta of Leaf System Pro ready.
If anyone would like to check it out, please send me a PM.

 

Looking great John, love the Gaia integration that automatically adds it to all trees. Brill.
Another great addition to your zone system.

 

id love to test it in my project john!

 

Just send me a PM

 

Hey John,

Would this work with other terrain creations systems like Map Magic and World Creator. I do have Zone controller pro so would to try the beta. Is there a video demonstrating its setup?

 

Yes,
It works completely on it's own.
I wrote some Gaia specific setup scripts, but the tool itself works in an empty scene with just a plane

I do have this quick video showing how to set it up got Gaia:

The normal setup is almost identical, you will just go to Window->Leaf System Pro->Scene Integrator and that will launch a tool window that assists you in setting the Leaf Zones up.

Send me a PM with your contact info and I will get you setup in the beta.

Thanks,
John

 

So, development is coming along nicely.

Presently the only outstanding items are to finish the documentation/tutorials and add the rest of the leaf content.
I am happy to announce that following the lead of what I did with Zone Controller, I will be releasing a FREE version as well as a PRO version.

The FREE version will operate identical to the PRO version with the following exceptions:
-Only 10 leaves allowed per Zone
-Only 100 Leaves per Scene
-No Source Code
-Only 3 leaf models will be included
-No Tree Matching tool to sync the Leaf Zones to Speed Trees in those Zones
-Only 1 Active Leaf Zone allowed per scene at Runtime. (you can setup as many as you like, but only 1 can be active)

 

Those of you participating in the beta, there is a new build I put up this morning in the Google Drive.
New massive performance increase on scene startup and new tool in the scene integrator that will match clusters of trees into a single Leaf Zone.
