Can somebody please explain me how to break my mesh into pieces (SubTools) so that I can attach a different material and colour to each of them or that I can change Subdivision level of each part ?
Thanks
Use the partial mesh visibility tools to hide everything except what will become one of your SubTools. Then press Tool>Polygroups>Group Visible. This assigns the visible polygons to their own group. Repeat for the rest of the model.
When your model has been grouped so that each group represents what will be a different SubTool, press Tool>SubTool>GrpSplit. This converts all polygroups to separate SubTools.
GREAT !!! Thanks a lot Aurick. I really appreciate yours “direct to center” explanations with out of unnecessary theories:D
I find this option very usefull when I need to apply some colour or material or even higher subd level at just one particular part of the mesh.
But I noticed that , for example, If I take SuperAverageMan as a tool and subdivide him at the level 3 , then use head as a separated subtool which I want to subdivide more then the wholle mesh , maybe at the level 5, my mesh will get crack in the part where the polygones of the head and the body was connected. Is there any chance I can avoid this bad looking mesh cracks in the places where 2 polygroups come together (and one polygroup has larger amount of subdivisions than the other) ???
Thanks.
After splitting, press Tool>Geometry>Crease. This will prevent the edges from pulling apart when you subdivide.
Thanks again Aurick. Yes, this can be solution. I say “can” because I can’t succeed everytime I do this operation. What I mean is that I can still see some little holes or tiny cracks on the connection line of the 2 polygroups. Now they look better but I noticed that this method will work best (and maybe perfect) on high poly meshes. If I use SuperAverageMan with 6 subd levels and few million polys I can use CREASE EDGES and divide a head (for example) as a separated polygroup 2 or 3 times without of cracks. But if I use SuperAverageMan with 2 or 3 subd levels this method won’t give me good results (although I use CREASE EDGES at level 15 which is highest level I can use).
So, this is very good feature for high polycount meshes (in order to subdivide particular parts of the mesh) but not for low poly meshes because it comes to mesh cracking.
Am I right ??
