Terrain Water Erosion

The Terrain Water Erosion component is a filter performing a realistic water erosion for Unity Terrain.
Terrains which we use to see in real life contain footprints of water erosion and our eyes can detect them automatically. So, we want to see the same footprints in games. But it is impossible for most of the artists to make such terrain manually because water erosion is a long integral process influencing the whole surface simultaneously. The only way to make a terrain with water erosion is to model this process.

If you have questions you can ask them here.

 

Here is the documentation about Terrain Water Erosion

 

I promised to underline here that if you use a new flat Unity Terrain with TWE plugin it will remain flat because water doesn't flow on a flat surface. So, add some geometry to the terrain and enjoy.

 

(I'm the dummy who didn't understand why nothing is changing... my terrain was flat )

 

Great looking tool. I hope to pick it up soon. Was wondering though, can you limit the effects to a certain area, like above vs below sea level, etc.?

 

Of course, I can limit the effect. It's realy easy. But I don't know what data I have to use for limitation. In some cases developers want splat maps in others cases they use additional maps or height field. So, I supply ALL the source code. The code is VERY short and clear. Just several dozens strings. Modify it the way you want and be happy.

 

Hello!

We were just discussing your asset and other tools that deal with water paths and erosion... mind you the videos I referenced were not available as tools for Unity. We were discussing how a tool might be very useful that could map a path for a waterfall during editor time and be used to maybe make a mesh or a path for a water asset to follow, Someone mentioned using a cloth simulation which was interesting... here is the post where I referenced a few videos of such effects.. http://forum.unity3d.com/threads/ga...nd-scene-creation.327342/page-98#post-2548911 but since you have a Unity asset that is doing erosion, I wonder if in your code is such an ability perhaps to create an asset to do such a waterfall/stream type thing?

There does appear to be a market and keen interest in it.. The name 'WaterFalls Pro' is still available i think

 

My asset just supply a simple and clear code for good looking hydraulic erosion. Everybody can take it and insert in his own tool for terrain editing. I didn't want to supply a ready tool but the algorithm itself. It contains just several dozens strings.
If you need more powerful tools for terrain editing you can use for example World Machine. The best samples of terrain which I've seen were made by this tool. As far as I remember there is a free tial version of this tool.

 

I want to buy the "Terrain Water Erosion", but first I have some doubts. If possible answer me.
Is this package compatible with Unity 2017, v3?

 

Hi Norberto,
I've checked it for 2017.3. It works right from the box without any warning.

 

nothing happens when i try to texture the terrain, even though i added the textures and selected them. I also selcted the Crag and Sediment exactly like shown in the video

Hi carmeline,

In accordance with screenshot you use “Erosion Brush”. I have an asset for erosion called "Terrain Water Erosion".
How to texture a terrain in “Erosion Brush”? It's better to ask the author of this asset.

 

Version 3.0 is released. It uses Burst, Jobs, Mathematics and Entities. It works more then 50 times faster. It can add sediment texture to terrain. I made it on Unity version 2018.4.
I used this plugin to create this landscape:

 

Here is the documentation.

 

Hi! Nice plugin, but I have an issue. Maybe I lost any step, please, help me. It appears in the end of the erosion process

 

Hi vladalejnikov,
You want the asset to set some textures on the terrain. So add some textures to the terrain and set indexes for them. Asset detected that indexes are grater then the number of textures on the terrain.

 

Thank you. It's not clear for a begginer like me...

 

Excuse me, one more stupid question. The original scene generates this splat map out of terrain. How can I get it for my terrain?

 

When you apply splat-map to the terrain each color in the splat-map becomes an appropriate texture on the terrain.

 

I purchased this recently..but I guess it doesn't support multi-tile terrains?

 

Yes. You are right. It doesn't support multi-tile terrains. I made special modifications to support it for one of my projects.

 

Hello, I just purchased this asset. When I install it I keep receiving an error :

" Assembly 'Unity.Properties.Codegen' is a CodeGen assembly and cannot be Auto Referenced (Packages/com.unity.properties/Unity.Properties.Codegen/Unity.Properties.Codegen.asmdef)"

This is with fresh clean projects, using Standard Pipeline Unity 2019, 2020, 2021 with Jobs, Burst, Entities, and Mathematics installed. All three projects that I installed this addon into would only open in safemode after install. Any help would be appreciated. Please and thank you!

 

" Assembly 'Unity.Properties.Codegen' is a CodeGen assembly and cannot be Auto Referenced (Packages/com.unity.properties/Unity.Properties.Codegen/Unity.Properties.Codegen.asmdef)"

was waitin if something change with new unity versions..-- that error stays -- ruins complete projects... dangerous to import without backup..

never been solved so far

or ?
