Curved World includes big amount of shaders for all type of devices - from ancient mobiles to high-end PC and consoles.

Your great game needs more shaders? No problem, Curved World has the easiest custom shader integration system.
Just 2 lines of code and

Almost any asset from the Asset Store can be made Curved World 'friendly'.


And not only from Asset Store!

Before purchasing try PC Demos and check documentation for better understanding of the Curved World and how it works.

Released!



If during importing asset Unity prints to console window:
MaterialEditor: Could not create custom UI from the CustomEditor: '' of the shader. Does the class name include its namespace? And does the class either derive from ShaderGUI or MaterialEditor?
Do not worry, just clear log window. It's Unity strange 'bug' and does not impact Curved World in any case.

This looks amazing, always loved the little planet panoramic images Straight into my wishlist!
Just a small question - in your little planet images i dont see an example with sky/clouds, is the sky also beeing curved or is that something beyond the plugins capabilities?

 

Huh, COOL!

Would this work well with giving large terrain a curvature similar to the real world?

Like, would this be precise enough to show a horizon drop off 6 miles away with a camera 6 feet off the ground. Just like it does in real life.

One of my biggest hang ups with modern terrains is that the horizon always looks wrong and flat.

 

Idea of Curved World is never ending curved horizon, while with meshes and terrains it works - it is impossible to curve skybox, cause it has its bounds. But its easy to imitate skybox moving by adding particle or clouds, Curved World will handle them.

Yes.

Would it be possible for you to upload more web demos with little planets for us to check out?
3. Little Planet - Deferred Rendering, Physics and NavMesh.unity
4. Little Planet - Projector and LensFlare.unity
5. Little Planet - Terrain, SpeedTree and Water.unity

I still don't understand yet if it's possible to have fully spherical little planet.

 

Making example scenes as web demos is not planed. Because there are not optimized for that. Just demonstration of possibilities of Curved World with lots of dynamic rigid-bodies, point lights, navAgents. trees and so on.

Sounds to me like this just became a "must have" for proper terrains.

 

Fantastic, it fits on a few projects of simple games I plan to develop in the future.
Surely came into my Wishlist.

A question about Little Planet:
It creates a fully spherical planet ? can give a complete turn around the planet, or the movement is limited by the edges of the terrain mesh ? If this is possible it will be really amazing !

 

Curved World bend exists only inside camera during rendering. In real world (editor) everything is flat (except mounts on terrain and such things). Yes you are limited by bounds of your game world.
But making full turn around may be done with some 'tricks', for example invisible portal.

Congrats on the release, looking forward to running it on my current project. Downloading update now!

 

Where/How do I setup curved world to work with the Unity Standard Shader?

 

Hey, I bought this asset and I had a problem with my version of unity 3D (5.0.2f1). We have already started our project, is there a solution to fix the problem or we have to DL a new version of Unity ? thank you

 

Could you please consider including a portal script / prefab in the package? I'm sure many customers, including myself, would really appreciate that... Preferably if compatible with Unity Free, not using rendertotexture

 

Portal was just an idea for game design.

Thanks or the info.
I'm using Unity 5.1.2, and had to update Curved world twice to get the current version (I had previous version)

 

Hi, I´m don´t know to much about shaders but if you could help me with something... on my game I have this lines to control the curve of the game, with other version of curve shader, I would like to know how could I get working with curve world shader,
Shader.SetGlobalVector ("_Offset", curveOffsetValues);
Shader.SetGlobalInt ("_Distance", Distance);

many thanks

 

Right, although I'm not sure how else to create the 'Little Planet' effect in CV2 without portals. If it's something you have floating around, I'd be happy PM you or pay a little extra.

 

Congrats on completing this update.

 

This is what I'm getting

 

Thanks

All curvature parameters are updated using CuredWorld_Controller script. Check example scenes.

I don't know if the packages uploaded to the unity versions are messed up or what, but The package I get with version 1.1.2 looks nothing like what you have listed on the asset store.

 

Hey John, take a look at the attached screenshot of CW2 in the asset store (taken from inside the Unity Editor).

The version number should be 2.0 and you need to be using Unity 5.1.1f1 or newer.

 

Yeah, I have 5.1.2...

 

As Such

 

same for me!!!

 

Is the asset store not giving you the option to update? Are you sure that you are signed in?

I ask because, every once in a whilte, I find that I need to re-sign into the asset store within the Editor.

Edit: Here's a screenshot showing how to check if you are signed into the asset store:

 

Yup, Signed in, From Unity, I updated 3 times now...still getting the old package.

 

I know that (as an asset publisher) managing packages for Unity versions is a pain in the neck with the release of 5.x
You have to maintain different versions for each build Unity makes, and thus have to keep a copy of each copy of Unity on your machine so you can submit with the corresponding version. I guessing perhaps the incorrect package got uploaded for 5.1.2

 

Hmm... Sounds like a Unity issue to me.

Have you tried the web version of the asset store? You should be able to download it manually that way.

Also, you might want to try clearing the folder from the asset store cache.

If you are on Windows, the cache is here:

C:\Users\[Your Profile Name]\AppData\Roaming\Unity\Asset Store-5.x\Davit Naskidashvili\Shaders

 

the menu it is different!!!

 

Tried web download too, tried deleting that too(mac equivalent )

 

I see now.

I have 5.1.2p2 installed. As you can see from my prior screenshots, the update is available for me within the Editor.

 

Can confirm that

 

I noticed we are both Mac users...I wonder

 

yes I´m a mac user too.

 

I was just going to write that it might be a Mac issue, but it seems odd that the web version of the asset store is giving you the wrong version as well.

I have an iMac at the office but I'm working from home today.

If this issue isn't cleared up soon, I'll test this at my office.

Is it possible that it's an asset store sync issue? Like maybe they have different servers for different regions and that the server you are connecting to isn't updated yet?

 

There are two packages of Curved World 2 on AS server one for Unity 4 (OLD) and for Unity 5 (NEW)
Both are v2.0, but which one you download is defined by Unity editor version.

Try cleaning asset store cache:
PC - C:\Users\[Your Profile Name]\AppData\Roaming\Unity\Asset Store
MAC - "~/Library/Unity/Asset\ Store".
I can't help more.

this is what iI get with football sample scene

 

That's old version for Unity 4.
Try cleaning Unity cache folder - "~/Library/Unity/Asset\ Store". and then re-download.

I clean up only your folder, and on asset store on Unity shows Curve World, I downloaded and the same happens, but I´m going back to asset store and shows me Curve World 2 for update. is that normal?

 

I have removed Unity 4 version from AS server. Now you will be able to download Curved World 2 without problem.
Curved World for Unity 4 (old version) is by request. If someone will ever need it, send invoice number to vacuumshaders@gmail.com

I got it to finally install correctly, but I had to just open the .unitypackage from my cached assets, instead of importing from the asset store window in the editor. Strange

 

ok I just have to delete cache folder Download version 1 and then update to version 2, but if version 1 was removed then just have to download and import normally version 2...it is working now...

 

W00H00!!!!
Finally, after waiting for like forever to use this on a project, I got it working!
I must say, it's everything I hoped it would be and more, the new version seems to be much easier to use and get running. I had a few issues getting all of my particle shaders to work out properly and with very large planes, but once I tweeked those out, it works like a champ.

 

In the WIP thread you said:
"Converting your custom shaders to Curved World 2 will be very easy - it's just 3 lines of code to add."

What are these 3 lines of code?

 

Now it's just 2 lines of code. Check Doc folder - CustomShaders.pdf

Hey! Great asset so far, I love how easy in comparison to the original Curve World to create custom shaders!

I've had a small issue though, the anti-shadow seems to be unaligned. http://s.odowd.co/QQm.png

Your shader has no ShadowCaster pass. Add it or use Curved World fallback shader described in CustomShaders.pdf file.
