Connect the edges somehow?

[heromade]

Hey,

I am using a shader to transform the vertice positions. Now as you can see in the image on the left side when I create a normal Sphere or Cube with Pro Builder and apply the shader to it the edges are not connected to each other.
If I use a normal Unity Sphere it works perfectly, if I use a normal Unity cube it has the same problem. But I need the Pro Builder tool for defining the amount of faces anyway, so that does not matter.

When I use the smoothing tool from Pro Builder (Shown on the right side of the image) it somehow connects the vertice normals to one and the shader is applied correctly, but I don’t want the sphere to be smoothed. I just want the edges connected and keep the “flat low poly” style.

Now does anyone have a clue how to connect the edges/vertice normals or whatever I have to do to make this work?

No one got an idea?

Have you tried “weld vertices” ?

Have you tried “weld vertices” ?

I just tried that but it is not working either

I just read your first comment again. Same thing happened with a cube? I’ve never seen that before. May I ask what version of unity you are using? I can try to recreate what you’re seeing.

One option might be to use a flat-look shader, have you checked Catlike coding’s tutorial on the topic and the thread I linked to below?

Flat lighting without separate smoothing groups?

Hi there, I'm pretty new to ShaderLab so I might be missing something obvious, but I'm having trouble writing a shader that simulates flat lightning, like so: [image] Now, the obvious way to do this is to just break the smoothing groups apart when importing the model. The problem with doing this is that most of my animated meshes have a sort of shielding effect layered on top of them (similar to Halo). The shield uses a transparent shader that pushes the mesh's vertices out by a specified …

Normal Extrusion as in tutorial is not working

Nothing, it's working exactly as it should. The shader pushes the edges out in the direction of the face normals. That means any edge with sharp normals, like that box, the faces will push out away from eachother as that is the direction their edges point. The example mesh is smooth with no hard edges, so the faces push out together.

maybe can try this,

Yeah, it was definitely the hard edges. Your displacement is being done using the vertex normals, and if there’s an edge the obvious result would be it could push apart. If you displace in world or object space, ignoring the vertex normals, you can avoid these issues as well.

You can see what happens with a cube in the link from post #7

Tried to use a flat shader (The Sub Shader Graph that is given in one of your links), but it’s not working.

My shader graph looks as follows:

Now I am not sure what to change. I understand that it uses the vertice normals, but the main problem is that the pro builder sphere/cube does not connect them unless I use the smoothing.
