I was watching and copying the video by the pitchipoy guy. Everything seemed good. Generated a rig that moved around like the video said it should.
Then I ctrlP-weights as in the video and nothing much happened. The mesh got a load of def-vertex groups but nothing in the mesh responds to any movement of the rig in pose mode.
If I switch the modifier to envelop, the mesh distorts horribly, but at least it reacts. In the default vertex mode, nothing.
Also if I select the mesh and in edit mode select in the panel some vertx group and click select, nothing lights up on the mesh.
The model was imported and was purchased some time ago for use in other software, it has been exported from DazStudio in what studio says is suitable for Blender (Y and Z reversed)
Any ideas? V2.73
