Normal map, Material export, character question

Hello guys! I have some questions and i didn t know where to ask so i hope this is the right place!
My first question is about baking normal maps, ambient occlusion etc but basicaly normal maps! How i bake them?
The second question is about materials. Im using unreal engine 4 and i would like to know if i can export the diffuse color for example from blender and pass it through ue4!
And the final question is weird. The baking from high to low poly is used to characters also? Lets say i have a finished character. How i texture him? Thank you for your time!! :grinning:

These are all very basic questions not just with Blender but with 3D graphics in general. This forum is more for specific problems and answers. I suggest looking up 3D modelling vids on Youtube, there are lots of free tutorials out there.

Thank you for your response! But im in 3d for two months now and i need to develop a game for my diploma thesis. The things i asked are the part that i don t understand at all…
