Creating a high detail normal map for a game engine

[system]

I created a simple high detail rock with dyna mesh and it has only one subdivison level.

Now I want to use this in a game engine, so I used zremesher to retopo the model. I duplicated the subtool,used zremesher and created a uvmap with uvmaster.

Now I want to create a normal map that has all the detail from my high poly model. How would I do that?

I solved it, just needed to subdivide my lowres mesh to level 6 and then project all the detail.
