    Hello,

    Do you know if tessellation is expected to be supported in LWRP (soon to be renamed Universal RP) ?


    Thank you

    Hi!
    Yes, it should be, as it has nothing to do with the render pipeline at all.

    Im pretty sure its supported now, just try writing a shader with a tesselation stage and see if it works? There are examples on unity docs that should work

    I'm not quite sure it does, altough I might be doing something wrong.

    For instance, the second example of this Tessellation shader does tessellate the triangles of the model, but the material renders Pink:

    unity3d.com/Manual/SL-SurfaceShaderTessellation.html
    (if a moderator sees this, please edit my message to insert the correct link, I can't post it)

    This seems legit since LWRP does not support Standard Surface Shaders, tessellation being one of the options of the standard surface shader.

    You can check this asset:
    assetstore.unity.com /packages/vfx/shaders/directx-11/dx11-tessellation-displacement-37322

    (remove the space between .com and /packages - if a moderator sees this please edit my message, the link provides a free solution to the problem)

    The dx11-tessellation-displacement is not supported indeed on URP.
    So @aleksandrk tell it should be supported but I cannot figure out how/when ?

    I'm not sure, what exactly do you mean.
    Tessellation itself has nothing to do with the render pipeline.

    Any news on this issue? I tried the tesselation sample from the unity website in a universal rendering pipeline and it just shows magenta and no errors.
