I’d like to have some sharp edges to this model… I have crease at 1.000 in some edges, but they still aren’t very sharp. So what to do?
You may want to make some parts separate and not subsurfed, but parented to the subsurfed model. You could then use the edge split modifier to set up smooth and hard surfaces in the same mesh.
You might also try setting up loop cuts and sliding them close to the edges you want to be sharp - you won’t have to get them too close, just enough to push the edges outward and make use of the crease.
Try a gradual crease. You have your loop set to 1.000, set the adjacent loops to 0.500.
This will help take some pressure off your crease.
Doesn’t always help, though.
If that doesn’t work, see post #1
