I'm trying to use
Limited Dissolve on a larger model, which brings the model down from
600k vertices to
100k vertices (no this is not hand generated :)). Below, you can see a much more simplified model just for this problem.
I created a plane that was sub-divided into several faces. I then extruded the edge faces to create a wall as seen here:
I selected the edge faces by going into
Edit mode, then
alt + RMB and clicked two of the faces around the border to give me the selection seen above.
In this model (same problem I have in my bigger, more complex model), I have several extra vertices and subsequently faces, that aren't needed. For example: Since the exterior wall is a straight line, that could just be a single quad.
Alas, I came across
Limited Dissolve, which I think is exactly what I need to be using. So, in
Edit mode I pressed
A twice to select everything, pressed
X and clicked
Limited Dissolve. That produced this:
I unfortunately now can't seem to use the
ALT + RMB to select that same outer loop as seen in the first image. I need to be able to select the edge faces as seen above to apply texturing across large segments with lots of faces, but the
Limit Dissolve seems to break that ability.
Furthermore, why do the face centers (the dots) seem to no longer be centered in the quads?
I found some similar posts regarding edges but not with regards to the face loop selection:
