► Wireframe shader - The Amazing Wireframe shader ◄

so that works as long as I only have 1 plane in the scene. I need to have this effect running on multiple groups but the wipe is at different speeds. The dissolve is working correctly with 2 planes moving at different speeds. However, wireframe wipe only seems to correspond to one of the planes, even though they have been set in the scripts and materials as plane1 and plane2 correctly...

Which is all part of how shaders work... they are both adjusting the same keyword parameter... I need 2 shaders if I have 2 planes - study and learn...

back to the drawing board for a bit...

 

Do not modify included script, changes will affect other scenes and materials. Instead, invert plane mask from ShaderGraph - Plane (Mask) node has invert property, use value of 1 there.

thanks and this is the difference between knowing how it works and hacking a solution
I will revert the script to what it should be and try and understand the actual shader graph to make it work correctly.
I will then explore further on the proper way to have more than one plane causing the wipe effect... It is something to do with the variable names, I can see that... Can I create a second instance of the effect and have a different variable name in the shadergraph? I think it is the .cginc script in reality?

 

You can create as many materials as you need, each one with its own mask. Just update those masks and materials using separate MaksController scripts.

thanks for the swift response Arkhivrag, but I think I must be doing something silly then...

I have 2 different materials and 2 different plane masks. I have 2 different mask controller scripts but because they both have the same line:

materials.SetVector("_WireframeShaderMaskPlanePosition", maskObject.position);

then the plane is set the same on both of them even though Plane1 and Plane2 move at different speeds...

As you can see, the dissolve effect is correctly following the Plane location but the Wireframe is following the right side plane, even though the left wireframe controller is set to plane2 and the right one to plane1

Do I need to set up the above variable as something like WireframeShaderMaskPlane1Position and then in the other shader/material I would set up a WireframeShaderMaskPlane2Position?

sorry for the silly questions but also thanks for all the help!

 

I have just re-checked shaders and it is definitely not possible to update multiple wireframe masks. Only one mask works.
Something has been changed inside ShaderGraph (or rendering core files) since creating wireframe nodes for it and I need to re-write them.

[Edit]
Problem is in SRP, built-in RP works without problems.

Once again, thank you for the help. Glad to know that it is not just me doing something wrong Think I have a long winter ahead of me trying to understand the whole shader graph stuff!

 

Hi - I have a very nice wireframe object (thank you Davit for this great set of assets!).

I am using Standard (Wire Only With GI) shader.

I would like to vary the Wireframe Thickness at run time in a simple script; is this possible and is there an example maybe? I have a feeling it might not be possible in a simple C# script... but always worth asking...

Thanks in advance!

 

Use Material.SetFloat().
Name of thickness property is _WireframeShader_Thickness

Still needs some tweaking but very cool, thanks for the simple & fast reply!

 

Hello, I'm not able to generate a wireframe mesh using the mesh generator window. When I hit the run buttton, I get a prefab with the standard (cutout wire) shader and no matter which settings I change, it does not show up (object on the right in the image attached). Could you please tell me how to fix this?

Engine: 2020.3.22f1
HDRP: 10.7

 

Standard (cutout wire) shader requires diffuse texture with alpha channel to render wireframe in the place of dissolved(cutout) pixels. Assign diffuse texture to the generated material or use other shader.

I've tried all shaders in the pack and they only show a base color and no wireframe unfortunately

 

Is problem with that particular model, or with others too? Are there any errors or warnings in the Console window?



Amazing Assets - YouTube Facebook Twitter

 

No warnings or errors. Tried with custom assets and Unity primitives

 

Do included example scenes work?
What about 6. Runtime example scene?



Amazing Assets - YouTube Facebook Twitter

 

They work fine in the example scenes as long as I don't touch any parameter in the materials. As soon as I change one of those, the wireframe disappears.

Some shaders have a floating point division by zero error but the ones that do not still suffer from this issue

 

It is very strange behavior.
Contact me on the support email (support@amazingassets.world) with asset purchase invoice and will continue discussion there.

I was using the Wireframe Shader in one of our projects. We are using Curvy Worl Asset also.

When we take the WebGL output after making necessary changes inside Wireframe Shader to make it compatible with Curvy World a pink color is shown up.

Could you please let us know how to tweak this?

 

Was wireframe shader working in WebGL before you modified it?

Hello,

I ran into a problem with Wireframe Shader in HDRP using Unity 2021.2.7f1 in the sample scene the wireframe is not visible. I reimported the shader folders and also tried to save the shader again in shader graph, but it is still not appearing. I am using HDRP 12.1.2

Could it be because of the HDRP version? I can move the project version back if necessary.

 

Wireframe shader has not been updated for Unity 2021.2 yet, but it looks like ShaderGraph has lost Dynamic Mask property there after updating. Try, open shader and enable Exposed checkbox:


Save shader and inside material editor re-select Dynamic Mask keyword to be None.



For any additional problems in unsupported Unity versions: Make sure wireframe is visible to a shader, check UV3 channel (here is saved wireframe data)

If mesh is rendered as in the image above, it means that mesh generator is working correctly and wireframe data is saved inside mesh.
Now replace UV node with wireframe node (Create Node -> Amazing Assets -> Wireframe Shader -> Read Wireframe).
Shader should render wireframe.

Hi there @Arkhivrag

Just using the shader pack in a Unity project and I'd like to programmatically change the color. I've done this using materialpropertyblocks in other shaders but I can't get it to work for The Amazing Wireframe/Mobile/One Directional Light/Addative/Simple/Wire Only

The inspector looks like this:



and I want to change the "Color" which is currently blue to something else. I'm using this code:

Code (CSharp):

1.            
2. props = new MaterialPropertyBlock();
3. Color newColor = Color.red;
4. newColor.a = 1;
5. props.SetColor("Color", newColor);
6. renderer.SetPropertyBlock(props);
7.  

but it doesn't do anything, can you or anyone else suggest a way to do this?

Cheers

 

Wireframe color property name inside shader is _Wireframe_Color
Material property blocks may not work as they are not implemented. In this case you have to integrate wireframe effect manually inside any hand written shader or Amplify Shader, all info in manual file page 13.

hello.
The store page says

• Mobile, console and VR ready

But the documentation says :

• for the runtime shader you need geometry shaders to be compatible.

But Metal for iOS doesn't support geometry shaders. So the runtime version doesnot work for iOS ?

 

Package includes collection of geometry shaders that calculate and render wireframe directly from shader. Those shaders do not need anything to be baked inside a mesh, but require device with geometry shaders support.
Those shaders are free addon for built-in RP and are not mentioned on the store page.

Main shaders do require wireframe to be baked inside a mesh (as written on the store page). Those shaders work on any device, have no any requirements or limitations and can be integrated into ShaderGraph and Amplify Shader Editor.
So if you are targeting iOS, bake wireframe inside a mesh and use 'non geometry shader'.

Thank you for the clarification. But I needed it at runtime for ARMeshing. I will find another solution. Thank you.

 

Wireframe can be generated and baked in run-time too. It is quite fast:

Hello, I'm having an issue with Curved 2020 and Amazing Wireframe shader. In essence, separately they both work great, but together I can't bend, twist or turn the wireframes.

I might be wrong, but a while back this used to be a seamless operation, right? What am I missing?

As for steps, I'm just changing a shader on the Curved 2020 examples to Amazing Wireframe--> Mobile--> Unlit. After this change, any objects that have it applied will no longer do any of the Curved modifications.

Can anyone advise on this? Thanks!

 

Did you activate Wireframe shaders from Curved World editor window -> Activate?



Amazing Assets - YouTube Facebook Twitter

 

Hello, I'm having an issue wit

I think so, I used the activate tool targeting the Assets folder (where Wireframe is) and it said a bunch of files where activated. However the shader still didn't work.

So, is it supposed to work out-of-the-box, correct?

 

And which Unity version are you using?

Do you have enabled proper Bend Type and Bend ID inside material editor of that wireframe shader?



Amazing Assets - YouTube Facebook Twitter

 

Hello, I'm having an issue wit

I'm using Unity 2021.3 and I don't recall having the Bend Type and Bend ID options on the wireframe shaders, but I'll check again.

 

But unfortunately it has limitations: "Those shaders require device with Shader Model 5.0 and GeometryShaders support. Currently dynamic wireframe rendering is supported only by Built-in render pipeline." (Manual of the wireframe shader package)

 

Run-time generated and baked wireframe does not need SM5 and has no limitations. It works on any device.

 

Does this wireframe plugin work on webgl1? What about webgl2? Does it work on Safari(iOS) and Chrome(android) without issues?

 

All devices are supported.

Hi,

Were there any performance tests done in Quest 2 to determine max supported triangle count for 72 FPS?

I've got a fairly simple model with 5-10k triangles and want to use the shader there but it needs to run on Quest 2 and leave space for other shader effects as well. With data being baked in to mesh I can imagine it's quite speedy and shouldn't pose much of a problem with those parameters in mind?

Also are there any gotchas specifically for quest/mobile rendering?

Thanks,
Chris

 

No problems on mobiles since 2014 (link)

 

Works great, thanks

 

So you are saying that the statement from the Wireframe Shader manual is incorrect? The manual version I have is from 2021, I guess it is still the latest. Did you improve the dynamic wireframe shader? So would it work with URP on a mobile Android device? How fast is the dynamic wireframe shader on mobile devices compared to WebGL? Can you give me performance benchmarks based on the example you upload before:

https://arkhivrag.itch.io/wireframe-shader

 

Manual is correct.
If you generate wireframe and bake it inside a mesh, then you use common shaders that work on any device without limitations.

However, if you are using built-in render pipeline and target device with GeometryShaders support, then you can use Dynamic shaders, that do not need wireframe generating and baking it inside a mesh.

 

Hello Arkhivrag,
It is me again, I got your wonderful shader two years ago and have already written to you. Now I have a problem with the WebGL again. Tessellation doesn't work. I attach the link as it turns out in WebGL build: https://nla658.itch.io/shaman
Whereas in the Windows version it builds like this:

Help me solve the problem, please.

 

Does WebGL support tessellation?

 

Does this shader support Alembic files? I mean an Alembic file that has deformation animation. It seems that the wireframe disappears when playing the animation of the alembic file.

 

I have never heard of such format before. After checking docs, it "streams the animation in Unity directly from the file".
Need to check how (and if) it is possible to modify those files from Unity to bake barycentric coordinates there, that is required by the wireframe shader.

 

hello boss, thrid year of using amazing assets, and as always, amazing! I got one question for this asset, is there a way to display a less populated version of the wireframe? Say that my object has alot of verticies, but i only want to show a simplified wireframe, is there a way to do this?

 

I understand what you are asking for, but - no, it is not possible.

 

Hi! is it possible to lit only Edges or maybe even vertices function maybe in the future? for instance 3d object that is without polygonal mesh

 

No edge or vertex rendering. Only triangle (and in some case Quad) edges that mesh consists of.
