I have googled this for a clear answer but i didn’t find …
what is the point of polygroups ??
THANKS !
Pretty good explanation here: http://docs.pixologic.com/user-guide/3d-modeling/modeling-basics/polygroups/
Lots of videos on Youtube showing different ways to create and use Polygroups as well: https://www.youtube.com/results?search_query=polygroups
It would be very hard to work without polygroups.
There are many reasons to have poly groups, it might be that you want to mask off one area regularly so making it a poly group makes it easy. also you can hide poly groups while leaving one group visible. you can divide one poly group on a mesh and leave the others undivided, for exporting to game development platforms you will find it invaluable to have groups for separate items that need to be animated but remain part of one mesh… that’s just a short list, there are many many reasons why they are useful.
What is the point of PolyGroups?
Well…
hehehe.
There’s too many to list but here’s the basics:
Polygroups are a way of dividing up a mesh into selectable parts without making separate bits of mesh, or objects. This allows you to make amazing selections with which you can do all sorts of stuff. Since you can always come back and select a PolyGroup in all sorts of diferent ways, its like having a selection that is persistent without getting in the way.
In the page Cad64 showed you there is a demo person and all of his various parts are divided up into polygroups, this means you can mask parts, hide parts, delete them, sculpt them, apply diferent effects to them, and not other parts, you can select one, or more, you can expand or contract your selections and do things like ring them with an edge loop or a bunch of edge loops while extruding and so on, its basically limitless.
Also in that page, at the bottom is a section called Working with PolyGroups, this is a FANTASTIC bit of stuff and bleeds out into direct editing and selecting your mesh in other ways as well.
Most of what I do is based on creating and extruding edge loops. It’s a friggin blast and definitely something to learn how to work with.
