I imported my completed hand model into the scene and followed the tutorial on attaching it to the arm. First off we rotated the forearm slightly to match the natural position of the arm when our hands are in this position. Because there is a lot more geometry on the hand than on the arm the first step is to match up the vertices that match the most closely to the vertices on the arm.
Once the main joins were complete ( which we did by holding down ‘V’ to snap the joins, we then went around the arm and merged all the joined vertices. That done we went back to the hand and merged the extra vertices together.
Once everything was merged we created some new geometry in the forearm to give the left over vertices somewhere to join. Not too many the tutor advises, he really likes to keep the mesh as low as possible so that it doesn’t crash the computer while we are working on the project.
All that was left to do now was scale, rotate and translate vertices to match the shape of our reference image.
