I have a sphere curved surface, and I have moved some faces which caused a shading issue. So I tried to do a data transfer, but its not working. And I'm also getting an error: Source and destination cannot be used in this case. What am I doing incorrect?

  • $\begingroup$ If your DT 'Mapping' is via 'Topology' , the source and destination must have corresponding geometric elements. Have you edited the geometry? $\endgroup$

  • $\begingroup$ Hi Robin. Sorry but I cannot understand when you referred to the DT mapping. $\endgroup$

  • $\begingroup$ Hi bb! I was just using DT as an abbreviation for Data Transfer. :) See answer. $\endgroup$

Your Data Transfer modifier is attempting to use 'Topology' as the means of mapping data from one object to another. Your objects do not have the same topology, so this wont work; Blender can't find a vertex on the source object corresponding to every vertex on the target object.

Instead, you could change the vertex-group which the modifier affects as follows:

(These are the vertices the modifier will not affect)

Then change the mapping of the transfer from 'Topology' to something more appropriate...

Here, because the source is spherical, 'Projected Face Interpolated' seems to work well.

Note the double-arrow to the right of the Vertex Group field is checked, to select the inverse of the 'TG' group.
