how can I bake normal map which is sculpted in Blender?

[Anonymous]

I made my object in Maya and sculpted the object in Blender (made scales and textures)

To use it for normal map how should i bake it?

do i have to bring the object as obj file and import to Maya?(it couldn't bring all the details)

or can i bake normal map in Blender and use it in Maya?

I should use(render) the object in Maya anyway
