► Curved World ◄

Curved World is a shader. Use it on all objects you want to be bent.
For controlling curvature use CurvedWorld_Controller script (one script per-scene).

Thank you for the reply. Being so new to this, I really do need more specific help. If I create a terrain in Gaia, what would I need to do to achieve the small world look when moving around the terrain?

 

From Curved World's settings window import Unity Terrain and Nature shaders. Create new material with Curved Worl/Terrain shader and inside Unity Terrain settings change material type from Built-in to custom, use new created material.

Hi, i purchased Curved World last year and i love it, i am using it in one of my projects since then (its a mobile game), yersterday i updated Unity to 2018.1 and updated Curved World to the last version too, and i had problems when compiling to Android, the console shows those errors:

I fixed it excluding the standard shader package from Curved World Settings, it was solved for me because i am using only Unlit and Particle shader in my game (and Universal bend type if it helps), i don't know if is only a problem with my project or more people are getting this problem too.

 

Hi. I am trying to use this asset with Unity 2018, using the latest render pipeline.

Now the problem is that I’m unable to use this asset,
Because when I use, for example, the lightweight render pipeline(LWRP), it forces me to use its new standard materials, or else it won’t render.

Is there a way to “port” this shader to be used with the new render pipelines?
Is there a way to kindoff fallback to different shaders with curved world ones or do you have any suggestion in making this work?

My second question is, are there plans to support those new shaders?

Thank you very much, our studio love your asset and we all think it’s great!

It would be great if we could integrate curved work to our latest titles, which render much more nicely because of the new LWRP.

Thanks!

 

Working on fix.

SRP is still in preview without enough documentation. Releasing fully functional polished asset and provide support for it currently is not possible.

Hi, I'd like to know if there is a shortcut to disable/enable Curved World Controller in Editor?

And if not, would it be easy to do it myself (how)?

 

I also want to manipulate the Controller’s values on runtime. How can I do that?

 

Is this a shader that we attach to the camera or I have to assign it to each GameObject in the scene?

 

There is no key shortcut, but in editor Curved World can be disabled from controller script


For manipulating curve values from script (run-time) check API.pdf file in Doc folder.

Is there a way that I can do this myself?
Correct me if im wrong wouldn't porting CurvedWorld for SRP is just a matter of changing a few lines in the shader? since its just have to fallback to a different shader?
Or am I wrong?
Id be glad if you could give me a suggestion for implementing this myself.
I will also share the results here so people can use a temp solution for that.

To clarify: the current problem i am having is that the render pipeline does not support the unity standard shaders.. isn't curvedworld just a layer above unity standard shaders? there is not way to easily change curvedworld shader to use the render pipeline shaders?

Thanks.

 

Hello,

Thanks for this awesome asset.

I have a question: how can I work with TextMeshPro (in 3D of course) ?

Thanks!

 

Yes, implementing Curved World into shaders is very simple, just adding one vertex transform method inside vertex shader.
Problem with SRP is that it's shaders are not Unity built-in resources yet, you will have to download entire SRP shader library from Unity github and modify all required files there. Also they are frequently updated and modified, you will have to overwrite your shaders too to keep them up-to-date.

Currently there are no TextMeshPro shaders included, you will have to modify them manually.
Bookmarked for the next update.

Making progress now but there seems to be a bug in 2018.1 When you import the Curved World shader into the project, there is no link to Vacuum Shaders under the Window menu and so you cannot bring up the settings controller. I have to save the project, exit, then reload the project, then it appears.

 

Hi there, this asset is awesome!

The description says that it works with Toon Colors Pro 2. How can I apply the Curved World shader to materials that are using the Toon shader?

Thanks!

 

Check Toon Colors Pro 2 documentation or ask publisher, he knows it better.

Working on new bend types: Spiral

That looks great!!! Awesome job.

I have a question about the models/assets that come with this plugin. Are they free to use in a commercial game? (I'm mostly referring to the road/cars in the Classic Runner sample.

Thanks.

 

There are here.

Oh, awesome, thank you!

 

@Arkhivrag, wow that spiral shader is nuts! Amazing. Also, I've noticed the link to your "readme" from the asset store blurb is returning a 404 at the moment.

 

@Arkhivrag does Curved World work with Line Renderer? I can't seem to get it to render correctly. Any tips?

 

Modify LineRenderer's points position using Curved World's API:

Code (CSharp):

1. public Vector3 TransformPoint(Vector3 _transformPoint, BEND_TYPE _bendType)

Check API.pdf file inside Doc folder.

BTW, 2. Little Planet (Nightmare) example scene uses LineRenderer for bullet trace, check it too.



VacuumShaders - Facebook Twitter YouTube

 

Awesome, thank you, I'll try that out.

 

Could this be used on voxel terrain like https://www.assetstore.unity3d.com/en/?stay#!/content/9180 so that when you fly up you start seeing a planet? Then you can fly around it and end up at another point back at the terrain and the closer you get the less bent it is, the further you get the more it looks like a planet?

 

What you are asking for (converting plane into sphere) mathematically is not possible.

Hi All,
I am trying to use the universal bend type. When the camera faces in the Z direction, then I can change the Y bend values to bend around the Y axis. But when the camera faces in other direction, lets say -90 degrees, then I cannot get this effect. Can someone please help?

 

Hi,
Can someone please help

Hi,
Can someone please help!!

 

Package includes Unlit example shader, check it. As for fallback use "Hidden/VacuumShaders/Curved World/VertexLit/Diffuse".

Curved World bends mesh along world axis, it is camera position/rotation independent.

@Arhivrag, thanks for your time and reply.
If I take the endless runner example from this package, currently its building the world in the Z direction. Then it uses the Y bend type to bend the word around Y axis. So, now if I form this world along -X axis, I should be able to get the same effect in -X direction by changing the Y bend type values right?

 

Is there a playable demo of the package at https://assetstore.unity.com/packages/vfx/shaders/curved-world-classic-runner-76725 ?

is it a complete game template with level editors, scoring, obstacles, etc., or only meant for rendering the world ?

 

Hello, thank you for this great asset.

I have also bought this asset: https://assetstore.unity.com/packages/3d/environments/kubikos-world-117341
But could not get it to work with curved world. The publisher said it needs to be able to work with UV Scrolling or UV panning. I was wondering if this is possible.

Cheers,

 

Hi,

Great asset.

I was wondering if it was possible to have either multiple cameras or pivot points? I'm experimenting whether its possible to 'fake' a complete little planet using the little planet effect.

Basically will just be teleporting or wrapping the camera when it goes past the edges of a plane as well as having additional cameras show the 'other side' of the planet.

Currently the second or additional cameras located at the other side or edge of the plane just appears distorted as the pivot point was set back at the original camera.

Cheers

 

No, mesh still will have the curvature along world Z axis.

PC demo.

If that asset uses some custom shaders, you will have to modify them to make Curved World compatible.

Curvature effect created by Curved World shaders are oriented to the world space and are camera position/rotation independent.
Each bend effect is correctly visible only from specific point, for example:
Classic Runner


Little Planet


Cylindrical Tower

When building this for iOS the curve is flat, as it would be if it wern't using the shader. It works on Android and PC. Any ideas?

 

Awesome! Thanks!

 

Hi, is there any support for occlusion culling due to the curvature?

I assume all the occlusion checks are done outside of the shader so everything is still being sent to the GPU even if it would be occluded due to the curvature. I'm sure I can tweak my far settings to handle this though so not a deal breaker, just curious.

 

Occlusion culling is controller per-object or from camera with included scripts.
Note, you still need objects to be rendered even if there are outside of camera view frustum, otherwise curved objects will disappear unexpectedly.

Hi, i found another bug, objects using Unlit or Outline-Unlit shader on Android devices renders with Rim Bias activated regardless they have that option turned off on the project (it behaves normally when running the game from unity), i don't know if it happens on other platforms. For the moment turning on Cutout rendering solves the problem but Outline-Unlit shader doesn't have that option.

 

Seems Unity has not removed keyword from materiel.
Try: Switch Inspector window to Debug mode and from materials Shader Keywords array remove "V_CW_RIM" string.

has anyone had any luck with cts?

 

Bought it, works great, but is there a way to also apply the curved effect to text meshes (either Unity's own or TMP?)

 

deleted......solved!
thanks & sorry xD

 

Maybe to TMP, but only those shaders that calculate text position in world space, most UI shaders do it in screen space.



VacuumShaders - Facebook Twitter YouTube

 

Yep, I meant 3D text, not UI.

 

Bookmarked for the next update. Planed for September.
