Here is a little mesh i made for those starting out with curvy
The reason i made it is to give a satisfying experience as soon as possible and to explore what curvy can do and to get
to grips with some of curvy's little quirks.
I have tried to make the mesh a good compromise for the wide variety of curvy sculpting tools.
save the obj file to somewhere convenient
import it to curvy
don't resize it ( at least not at first )
have a play with different tools and mesh mirrors etc
often have a look at the wireframe view to see what is happening
don't overwrite the original obj file then you can always reimport it when something goes wrong (unexpected behaviour )
