Tessellation on Android and IOS

Hello everyone, I try to use tessellation on IOS ( Ipad Pro 3º. Latest one ) and Android ( Samsung Tab S4- Adreno 540 ).

Samsung Tab S4 has opengl ES 3.2, so in theory must work D11 tessellation samples, but when I use them, I get invisible objects. If I compile for Vulkan, Shaders works fine ( Standard ) except tessellation that doens't work.

Same on Ipad Pro, Objects that use tessellation shader became invisible ( I can see their shadow cast ).

I test all tessellation functions without result. All of them works fine on desktop ( Windows and OSX ).

Are mobile devices not ready yet for tessellation ? is it an Unity Shader compilation problem ? or I mistake something ?

Thanks

 

I have the same problem. Is there a solution?is it an Unity Shader compilation problem ?

 

Mobile GPUs do not support tessellation.

 

I will. Thanks for your support

 

Bump. Have there been any news, guys?

 

I made a water shader in Unity 2020.1.6f1 using Vulkan with latest URP package, (I can not use OpenGL if I want vfxgraph), if I enable tessellation shader don't work when I build to the Oculus Quest. Works perfect on Editor.

Is there any plans on the roadmap to fix/support that?

 

No, I don't see anything just renders pink if I enable tesselation

I have attached the logs from adb

Can you please confirm if tessellation should work in 2020.1 and vulkan?

 

It is false in the oculus build, that means quest don't support tesselation at all? is because the gpu? may quest 2 works?

 

Thanks Aleksandrk,

If I understood well, this is something Oculus needs to support on their Oculus drivers and not something Unity still need to implement in Vulkan, is that right?

 

FYI I did the same test with Quest 2, and it returns true, so looks like tessellation is supported in Quest 2 and doesn't in Quest 1

 

Any example of tessellation shader for Android/IOS? I did not find any. The shaders I tried to write do not work.
