Hi Lordfox,

> Did you have also a example for the SYNC POINT option?

The sync points option allows you to control which spots of the edges will be connected together in the blend surface. By default the edges are matched by distance traveled along each edge, but sometimes it can be better to manually control how things match up.

Here's an example, since the bump in these surfaces are at different lengths along the edge, the default blend surface will sort of have 2 bumps in it like this:





That happens because the default connection between things is to just connect the same percentage distance traveled along each edge, which means the tip of one bump is connected to this spot on the other edge in this case:



You can manually control the connection by adding in sync points, for example adding in sync points in these 2 spots will make this result:




It basically allows you to manually control which areas of the edges will be synchronized with each other during the blend surface generation.
