Million of vertex/edges (don´t know exactly the name) well here´s the thing I´m new to blender and I started creating a model of a human figure which I will animate in the near future. Now I´m supposed to start with the retopology phase, which gets really annoying cause every time I select the edit mode, the surface of my model is full of these millions of vertex/edges/etc. which difficults my work cause it gets really confusing to create a retopology of my model.

P.S.: I´ve watched retopology tutorials on youtube in which the view of such mesh is disabled in edit mode to make the work easier https://www.youtube.com/watch?v=3VC98kiy10Q
So in light of your wrong retopo setup these are the steps you need to take.

Prep High Poly mesh
1. Turn off "show wires" and "draw all edges" on the high poly object.
2. Give this a dark color material with some soft specularity to aid in retopo work.



Prep Low Poly mesh
1. Create a new plane mesh to be your new low poly retopo object.
2. Turn on xray on the object property panel.
3. Turn on show face normals on the navigation panel in the 3d viewport.  

Prep Retopology tools
1. Turn on snap tool, on the drop down menu choose "face"
2. Turn on "snap to self"
3. Turn on "project individual elements on the surface of other object"
4. Turn on "automatic merge vertices"  

   


Learn the "F2 addon" or other addon suggested and use it to work retopology.
