How to easily remove vertices and edges or merge faces removing excess geometry?

As a simple test I started with a square face. I then extruded additional faces out all in the same plane to create a complex shape. I decide this is the shape I'm chasing but I'd like the faces to all be merged so they can be treated as one. I merge the faces but see all my old vertices and edges throughout my new face. I can't seem to delete vertices or edges, only entire faces or objects. There seems to be no way to clean up my object and I'm stuck with lines and dots throughout its surface. Is there anything I can do here? Is there really no automated tool or function I can use that will clean this up for me?

 

Very late to the party, but a method I used, was moving the vertex to the same point as its neighbour along an edge, select them both, then Weld Vertices. This removes the duplicate.

 

wow.
I can't believe there is no way to delete a vertex with pro builder!
Seriously, why is it still the case?
Seems like the most basic thing a mesh editor should have!

 

Hooray, I found the solution. You need to set a checkmark "collaps to first" and do as on this gif:

 

Well, that's a way to do it.
A bit convoluted but it works.

 

It triangulates tho, it pisses me off :-\

Also the face subdivide is annoying, it splits in weird shapes some times :-\

 

So, 2022 calling...Pro Builder still doesn't seem to allow deletion of vertices.

 

Yeah I'm trying to delete some edges or vertices in a simple manner and I'm not seeing any options to do so. On latest probuilder Unity Version 2021.2.11f1

 

Preety sad that we still don't have this feature, had to delete a whole model cus there was no way to delete the vertices and merge destroyed all the mesh... hope we get this 'feature' one day.

 

It's actually insanely hard to delete vertices from a mesh in Unity in general, even using the C# API:
The way the meshes are structured makes it so hard in fact that I just gave up and make new triangles instead, letting orphaned vertices in there.
It's ugly and eats memory on the final mesh, but there is no performance penalty in real time.

 

I'm trying to use the Collapse function at runtime to get rid of hanging vertices after I merge faces.

The aim is to use the "Collapse to First" option to collapse all hanging vertices to the nearest remaining vertex on the newly merged face. However, I cannot distinguish the hanging vertices from the ones that are part of the merged face.

The merged face object still has all of the original vertices that were part of the pre-merged faces in its distinctIndexes list, so I cannot tell them apart.

Does anyone please have any suggestions for how I can work out the hanging vertices after I merge faces?
