Hello.
I just started using this shader, and have question. I have mesh object which has more than one material (every material has it own shader). During application execution I am changing current material. Until I added material which has your shader it worked, but now I can't change material but always mesh is drawed by your shader. Is posible to apply on the mesh more than one material among which one will be with your shader?

Update:
I solved this, it works well now.

 

Is there a way to generate this in realtime, or via a backendserver script?
I need to make this workflow automatic.

is there a solution?

 

Hi, is it possible to give (and alter during runtime) the wireframe mesh different colors at all nodes?

 

• If targeting device with GeometryShaders support just apply Wireframe shader to a mesh and everything will work.
• If target device does not support GeometryShaders, then you will have to bake barycentric coordinates inside mesh with included tool in editor or run-time.
WebGL example with procedural mesh generating and wireframe data baking: https://arkhivrag.itch.io/wireframe-shader

Everything inside shader can be modified dynamically, including wire color.

So let's say I have a sphere and I could make the left side of it have a wireframe color of blue, and the right side green and the wireframe in between gradually changing from blue to green?

 

Gradient color of the wireframe can be achieved using only textures.

Is is possible to draw only certain lines? For example if the mesh was a plane with verts arranged into a regular hexagonal grid, could I draw only the lines that make up the hexagons and not the lines that make up thr triangles inside the hexagons?

 

Only triangles and quads.

I'm having a problem with the shader. The transition between wireframe and texture has a "gap", and I need for it to be solid wireframe. I'm not sure why this happens. I'm using the "Wireframe Mask Controller" (plane) and example that shows hides the when this one is moved

 

Does example scene and shaders there have the same problem?
What Unity version do you use?
What is build target?
Is the problem with all wireframe shaders or with specific ones?

Hi,

I am having build to IOS ( iPhone 6s ) but wireframe shader is completely dark ( with shape of mesh ), it works on macbook good, but not on iphone, any idea ?

 

You need to bake barycentric coordinates into the mesh.
Only GeometryShaders do not need any data baking inside mesh, but mobiles do not support those shaders.

Hi, we are using your amazing wireframe shader. This appears to be working fine on a PC but when we use on a Mac Geometry Shader -> Addative is giving us a pink shader. Is there something that we are doing wrong here? Our Unity version is 2018.2.2f1.

 

May be your device just does not support GeometryShaders.
In this case just use regular shader and bake wireframe data into a mesh.

Hi,

Is there any way to get this working with HDRP? I've been using the asset in 2018.3 with no problems but I get "maximum number (256) of shader keywords exceeded" error whenever I import it into a project with HDRP enabled.
Is there any way or workaround to solve this? I would only need to use Geometry Shaders.

Thank you.

 

Scriptable Render Pipeline is not supported by Wireframe shader.
It is planed to add first LWRP and later HDRP shaders, but will be they included in the current package are sold separately currently can not say.
It is just a big work to be done and requires all shaders to be completely re-written from the scratch.

Hello, I've bought your great asset and am trying to figure out how to change the DynamicMask feature so the wireframe is only drawn if the pixel is inside a box (like the existing feature, just with a box, not a sphere). The box is defined by a centerpoint (in world space), and a width(along the local x-axis)/depth(along the local z-axis). Problem is I don't know much about shaders or vector math. I'm sure that the change needs to be made in Wireframe_Core.cgnic, in the V_WIRE_DynamicMask(half3 maskPos) function. However I'm not sure what math is needed to make this happen (an alternative would be to convert from world space position to object space position). Any advice you can give, or resources you could point me to would be very helpful. Thank you!

 

Thank you for the info! I understand what you are saying about the shaders. I have an asset of my own that also needs a shader rewrite for SRP support, which I'm working on. The LWRP and HDRP API sets, both in C# and the shaders, are still evolving within Unity's team, and the documentation and examples are not yet complete. I was fortunate to get some face-to-face consultation with a member of Unity's team during Unite LA this year, and he said they really are working to stabilize the APIs and finish the documentation. I got some assistance in finding the APIs I need to use within the published source code, so I'm hoping to make some progress soon.

Point being, I hear what you are saying and will be patient because I'm in a similar position with my own code base.

 

Currently there is no Box mask type, but will be added in the next update, somewhere after New Year's holidays. Additionally restriction for the shaders to be inside main Assets folder will be removed.

Hi,

I have an iOS project that acts weird. I load a prefab resource and instantiate a clone to scene.
I have 2 object uses same wireframe shader material

iPhone 5, works great
2 of them great wireframes

iPhone 6s
1 of them good, 1 of them pitch black, Maybe a metal api issue ? But it is weird one acts good, one acts not good...

Using Unity 2017.1.3 patch 2

 

May be you are using asset for Unity 5.6.
Update Unity to 2017.4.10 (it is minimum supported Unity 2017.x version) and re-download asset.

Hi, I solved the problem... My meshes created with wireframe shaders were corrupted somehow, I had to delete them and rebuild new ones..

 

Hello - does this work with 2018.3? Thanks.

 

Works.

Just released new update with dynamic box mask.

That's a really cool feature! Now I have to look for an excuse to use it in my project.

 

Hi, would you be able to add a shader designed for mobile but with specular done per pixel not per vertex? Per vertex specular I find just too ugly, I'm currently using the physically based shader but it's too slow for my needs.

Ideally it would deal with more than 1 light (in just 1 pass, is that possible?). I don't need anything else, not even diffuse. It would be great to have an uber mobile shader (where you can turn everything apart from what you need off) but with per pixel specular.

 

Mobile One Directinal Light shaders calculate specular per-pixel using LookUp texture.
All other lights per-vertex by Unity.

Hi, any update in HDRP support? Thanks

 

Hi.

Developing games for mobile, a question. Docs says, if the wire source option selected as "Texture" instead "Baked", no baked mesh generation required, and it will be running on any device.

Can it run on OpenGL 2.0 like on iPhone 5, 4S ? Because I saw a comment says it does not work on WebGL from someone, but docs says no bake required if texture is selected.

I mean I want to use cars original mesh ( no baked from your tool ) and select texture source options, will this work ?

 

Currently HDRP is very unstable.

Three options for wireframe rendering:
1) Wireframe can be rendered from texture, but you must provide that wireframe texture yourself. Supports blendshapes and unlimited vertex count. Shader works on any device.

2) Wireframe can be rendered from mesh that has such data baked inside. Plugin includes such tool for editor and runtime use. Blendshapes are not supported. Max vertex count allowed is 21.000. Shader works on any device.

3) Wireframe is completely generated inside shader. No texture or mesh baking is necessary. Supports blendshapes and unlimited vertex count. Requires device with GeometryShaders support.

Thanks. Textures works like charm.

I have another question. I have 2 same objects, 1 wire-framed, 1 normal. They have to be in exact same positions. This creates z-fighting from some angles. I want wire-framed to be more obvious. Any idea about this ( I cannot change size objects and move them a little bit further to prevent z fighting ). Maybe some shader setting.. ?

 

You can try changing render order of the materials using Material.renderQueue

Can you check this is working? I have a base map with gloss in the alpha, I've tried various textures for the specular lookup map but I get nothing, no change visually. (One time I started seeing the gloss channel as what looked like a strange transparency, on deselecting the object it went away.)

 

If shaders are not to be used in VR try:
1. Open VacuumShaders\The Amazing Wireframe Shader\Shaders\cginc\Wireframe_ForwardBase.cginc file.
2. Remove lines from 12 to 21. Save file.
3. Right click on Shaders\One Directional Light folder and choose Reimport.

That worked, thank you

 

Hi, I have another problem with the specular part of the one directional light shader. It seems after a certain distance from camera the specular no longer works on Android. Please see the attached image (there's 1 directional light, diffuse is working fine, the plane is 220 units from camera)

 

https://monosnap.com/file/S9rW2CA8u8WE1e0umtf2pzDZqN7Rq6

 

As specular color and value are read from a lookup texture, all texture rendering issues will effect specular effect.
In your case it may be due to mipmaps.


Try disable Mimaps generation for that texture.

That didn't work I'm afraid. Do you have any other ideas?

Here are the texture's settings (though I tried changing several of these options, no difference):

It's all Android GPU and how it handles texture rasterization and I'm afraid I can not help here.

Hi, this asset looks interesting. I have a polygonal mesh structure with support for n-gons. This structure is then converted to a triangular unity mesh. Is it possible to pass the polygon structure for the wireframe? In other words can i say that some lines of the wireframe should not be rendered? I want to use it for android

Thank you!

 

You can't render only edges of a mesh, shader renders triangles and depending on vertex/triangle structure also quads.

@Arkhivrag Do any of the shaders support rendering the wireframe whenever a material is occluded?

Like this, but with the wireframe instead of shadow:


EDIT: Image and background information on this thread:
https://forum.unity.com/threads/ren...rs-with-ztest-greater-but-ignore-self.429493/

 

No. Added to a wish-list.

Thanks! Any advice for modifying one of the existing shaders to support this?
