System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 417.22

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-06-19 18:29, hash: d30f72dfd8
Worked: (optional)

Short description of error
The mix factor in the Data Transfer modifier does not work when using Custom Normals option and a vertex group. It works if you aren't use a vertex group. I would expect the vertex group to act as a mask similar to the Vertex Weight Edit Modifier.

Exact steps for others to reproduce the error

With default cube add a vertex group with some weights on the vertices
Add a plane object
Add a Data Transfer modifier with the plane as the target
Turn on the options Face Corner Data and Custom Normals. Any loop mapping option other than Topology should work. I use the default.
Add the vertex group to the modifiers property
Trying to move the Mix Factor property does not effect the result at all.

Attached a blend file Mix Factor Broken.blend

Thanks for the report, but this is working as expected currently, if vgroup is specified, mix factor is not used. Agree that could be changed (to multiply vgroup weight with factor probably), but that is something to be done later, and definitively not a bug.

Bastien Montagne changed title from ~~Data Transfer Modifier Mix Factor does not work with custom normals and a vertex group~~ to Make Data Transfer' Mix Factor multiply with vgroup weights when given, instead of ignoring it (warning, will need doversion!)
