Hey really nice Shader! Is it possible to add a Specular/Metallic map? Would love it to have more Detail with my own Specular Texture. (to the Legacy_Opaque Shaders)

 

Right now working on update for Unity 2018.
Will try to add SpecularMap option to Legacy shaders too.

Hi, I was wondering how your low poly shader would compare to the mobile/diffuse shader in terms of performance on mobile? Because I planned on replacing most of the shaders with this low poly shader for a low poly style mobile game.

 

I have not tested it on mobile.
Package includes Unlit, Legacy and PhysicallyBased shaders. There is no Mobile/Diffuse shader.

If compare Low Poly/Legacy/Diffuse and Unity built-in Legacy/Diffuse shaders, then the last one may be is a little bit faster (of course), as it has no all those "Low Poly" related features.

@Arkhivrag is there a way to add Dissolve support to this awesome shader? I really need it. Thanks.

 

Simple dissolve effect with edge size and color control - may be.
But Integration with Advanced Dissolve shader - currently no.



VacuumShaders - Facebook Twitter YouTube

 

@Arkhivrag for now, a simple dissolve effect with edge size, color control would be okay enough. Please make it happen.

 

Try new version v2018.3

@Arkhivrag Hi there, I deleted "VacuumShaders" folder, update the latest version v2018.3. But, I did not see any Dissolve option. I'm using Unity 2018.2.6f1.

Edit
I found Dissolve option, inside Cutout shaders. It works. Thanks.

 

@Arkhivrag Hi, I'm using Unity version 2018.3.3f1, DirectX 11 Low Poly Shade version 2019.1 - Jan 16, 2019. I got these 2 errors. Can you help me to fix it? Thanks a lot.

Code (CSharp):

1. Shader error in 'Hidden/VacuumShaders/DirectX 11 Low Poly/Legacy_Opaque_Diffuse_Bump_Specular_Reflective':
2.    invalid subscript 'objectPos' at Assets/VacuumShaders/DirectX 11 Low Poly Shader/Shaders/cginc/Geometry.cginc(145) (on d3d11)
3. Shader error in 'Hidden/VacuumShaders/DirectX 11 Low Poly/Legacy_Opaque_Diffuse_Reflective':
4.    invalid subscript 'objectPos' at Assets/VacuumShaders/DirectX 11 Low Poly Shader/Shaders/cginc/Geometry.cginc(145) (on d3d11)

EDIT
I still don't know where the problem is. I found a quick fix for it, by right click Shader folder, click Re-Import it to force the Shade to be re-compiled properly again.

 

Seems shader just was not completely imported. Right click and re-importing it is the solution.

Hi, we updated our Unity Version to Unity 2018 3.6f1 and now we get these 3 errors, when we export our game:

Code (CSharp):

1. Shader error in 'VacuumShaders/DirectX 11 Low Poly/Main': '' :  syntax error, unexpected LEFT_BRACKET at line 10 (on vulkan)
2.  
3. Compiling Vertex program with UNITY_PASS_FORWARDBASE DIRECTIONAL FOG_LINEAR

We export our Game to Linux x86_64 and use your last released Version.
Our System uses OpenGL 4.5

The exported Game gives us the following error messages:

Code (CSharp):

I was able to reconstruct issue. It exists in Unity 2018.3.6. No problem with Unity 2018.3.0
There is nothing from my side to be fixed.
Problem is in Unity shader compiler. I have just sent bug report.

Ok, we will try out some older Unity 2018 3.0+ Versions. Thanks you for your fast answer!

Edit: It works in Unity 2018 3.3

 

Some bug in Unity 2018.3.6 compiler. Hope will be fixed.

@Arkhivrag Do you know if it's just 2018.3.6, or that and above (specifically 2019.1). Looking into getting the shader, but don't want to rush ahead if it's broken on Unity's end in the version I'm in.

 

Went ahead and got it anyways. Did a mono build in 2019.1 and don't seem to have any issues at all.

 

Could this be used to render stuff in the distance in order to reduce cpu and gpu load?

 

Some Unity shader compilation issue in Unity 2018.3.6 on Vulcan only.

Shader does not reduce vertex or triangle count. But you can briefly reduce texture resolution as it is rendered per-vertex and no need to have it in HD quality.



VacuumShaders - Facebook Twitter YouTube

 

Is there a way to increase the intensity of the "low poly" effect? For example, I have very small triangles on some models but would prefer larger ones such as in your examples.

 

No, mesh is rendered using its vertices only.
What you are asking for can be achieved by adding tessellation pass.

Hi!
Is there any plans on making this shader compatible with Lightweight RP?

 

Shader requires GeometryShaders support and it is not included in LWRP.



VacuumShaders - Facebook Twitter YouTube

 

One more shader question, is it possible for this shader to work as a blend shader? For example, say I want a toon material as the base but then blend in a low poly effect over that (as a secondary material).

 

Shader does not support such effects.

Will this be updated to work with HDRP?

 

Yes. Waiting HDRP leaving preview mode.

Hi Arkhivrag,
Just imported LowPoly & Wireframe.
But as soon as I select 'enable wireframe' I see that the scene is refreshing (very short cyan mesh color) but then no wireframe!!. Is this a bug, or not yet supported in 2019.3? I don't have any warnings/errors. Just the wireframe is not visible. Please help.

 

Check ReadMe file in the VacuumShaders\DirectX 11 Low Poly Shader\Doc folder.
Note, it mau not work in Unity beta versions.



VacuumShaders - Facebook Twitter YouTube

 

The last line of the ReadMe states:

" For enabling papercraft effect check 'Integration_TheAmazingWireframeShader.cginc' file inside 'VacuumShaders\DirectX 11 Low Poly Shader\Shaders\cginc' folder. "

It does not state that, when wireframe is used, this file also needs to be changed.
Now I understand the reason why it didn't work, but it could be made a bit more clear.

 

I am using Unity 2018.3.0f and I noticed that an issue when I enabled anti-aliasing and built the game.
In the game build, the screen turn black when my player turn to face the object with the vacuum shader on it. This does not occur if I disabled anti-aliasing.

I guess this mean that the shader does not work with anti-aliasing and is there a way around this?

 

Where do you enable anti-aliasing? Shader has no such option.
What is build target?



VacuumShaders - Facebook Twitter YouTube

 

The anti-aliasing option is in the Edit->Project Settings->Quality, under Rendering.

I built it on the Android platform.
Minimum api level: android 8.0,
Target API level: Automatic (Highest installed)

 

Unfortunately I'm not able to reproduce your issue at my side.
Low Poly shader and Antialiasing option inside Project settings are not connected. It may be some problem at Unity engine side or with device GPU.

Hi there, the shader looks very cool. Just wander dose this shader work with real low poly mesh? Tried some shader with low poly style mesh and single material, the result doesn't look very low poly. I use orthogonal camera, the shader is not very sensitive to plane change under directional light, especially the shadow on mesh sometimes have spikes or crack, will this shader help with that? Also is this shader compatible with post process outline effect? Thanks!

 

Shader works with any mesh.
Note: shader does not modify mesh triangle/vertex count. Mesh is rendered using its triangles, but each one with unique color gained from material texture and generating flat normal creating 'low poly' effect.

Shadows are completely generated and rendered by Unity. This shader has no effect on them.

With Unity post processing - Yes. Have not tested with custom third party image effects, but I'm sure - Yes.

Are this shaders compatible with HDRP on Unity 2019.2 ?

i just import them and all the example scenes are just pink objects.

=(

 

Currently not supported.
HDRP is still in preview and rapid development.
Waiting for official "production ready" release.

Can i get the old version for unity 4.7.2 I really need this.

 

Unfortunately there is no version for Unity 4.7 and even not possible.



Amazing Assets - YouTube Facebook Twitter

 

Awhhh is it possible to convert the scripts for that version of unity?

 

Is there a timetable for SRP (HDRP or URP) given it's "Production Ready" according to Unity?

 

Unfortunately, currently no.



Amazing Assets - YouTube Facebook Twitter

 

Understood. Thanks for the response!

 

It will be defiantly updated in the future. It is just not in the first position in the queue of my assets requiring the same updates.

Is there a way to reduce the generated vertices from the Shader?

I'm trying to reduce relatively high poly models to low poly models, but even when using this shader, the poly count is still too high.

 

No, it is not possible to reduce vertex/triangle count of a mesh using shader, neither with this shader nor any other.
Increasing yes, with geometry or tessellation shaders, but reducing - never.

That ruins rigging right?
And topology.

 

Can this be done for unreal engine?
I would pay 100 dollar for it.
