Low Poly Vs. High Poly = What kind of Normal Map

tekkoontan

so on the left side is my low poly...

on the right side is my high poly...

because the high poly is smoothed, it is therefore SLIGHTLY smaller (in size) than the low poly...

so becuase i wanted to make a normal map to be put on the low poly, i am concerned about how the 'difference in size can affect the outcome of my normal map'. or it just doesnt matter?

i know i can just go ahead and try it out and see for myself but i don't know how to do it yet and i am kind of impatient and wanted to know the answer quickly. sorry but can someone answer to my problem?

also what if the low poly is smaller than the high poly? how will that effect the normal map?

look forward for your reply guys!

you should build your low poly with the closest dimensions possible to your high poly. In this case, add ~1.5x more geometry to your low poly to achieve a clean bake.

Also, you'll need to smooth (soften edges or set smoothing groups) that low poly mesh for baking.

if you need help baking msg me and I can show you on skype
