I wonder if it is possible to lower the resolution on masked parts of a tool? I have build a terrain that I want to have high in detail (lots of poly) in the front but low in detail (less in poly) in the back. I am looking for a way to make the document less high in polygon count so I wonder if I can ‘selective’ delete ‘masked’ parts of my terrain…
A better way might be to split up your mesh using polygroups.
Switch to the lowest subdivision level. Use the selection brushes (Ctrl+Shift) to hide sections and then go to Tool>Polygroups>Group Visible which will give the visible section it’s own polygroup. You can then go to Tool>SubTool and click ‘Groups Split’ which will split the different polygroups into seperate subtools. After they are split, go to Geometry subpalette and, in the Crease section, set CTolerance to max and ‘Crease’ the edges of all the subtools so the edges don’t deform when you go back up in subdivision levels. Now you can set a different subdivision level for each section.
Excellent, just tried this. Thank you for your help!
