I think there is nothing more useful in a 3D modeling app than a good simplify tool, that will get rid of redundant polygons on a mesh without affecting the important vertices that define its shape, making it efficient for whatever use, because when modeling a complex object, redundant polygons are simply unavoidable.
I remember in about 2001, when I was doing a lot of modeling on 3D studio Max for a short period (a few months), there was a plugin that was incredible on simplifying a mesh, it was really god-sent!
Now I can’t find something similar on Blender except decimate modifier which comes with a lot of problems:
It warns me that the mesh is non-manifold and refuses to work. I did some manual corrections with the help of Edit Mode/Select/Non-Manifold feature in vertices mode until no vertices were highlighted, but still it warns me for non-manifold mesh.
I’m already thinking to download a trial of an expensive app just to use such a tool (if it exists and is allowed in the trial) but that’s not a permanent solution! Another desperate alternative is to …manually re-mesh the meshes but that’s extremely counterproductive too!
PLEASE, to help other modellers too, my question is this:
What are the best procedures / addons / even external free -or as a last resort, low cost tools to clean up and make a non-manifold mesh correct and simpler, with fewer redundant polygons, efficiently, with as less manual corrections as possible for v.262?
