maya low to high baking process

model the low

model the high

align the model as necessary to specific bump

select the low then open the transfer maps box as it'll input the low res automatically

drop down the source mesh option , select the high res, and click add selected

enable a normal map transfer and use the desired settings (all i changed were the map resolution and sampling quality if necessary)

here are the results to a basic flat plane though in noticed some of my details didnt show up so i lowered my high res plane a past the low res to the poitn where they werent even touching, so that it wasn't completed matching with my low poly and got these results:

tips ive learned with doing this:

make sure the low is unwrapped properly
avoid 90 degree angles
if necessary, modify the distance between the low and the high if the transfer didnt go successfully while they were perfectly aligned
