stone_stairs NORMAL MAP ARTIFACTS,

Normal map artifacts, im using xNormal to generate them, I tried using maya's transfer map options but those are useless.

Why?




Why?!

In ZBrush, see if you have intersecting/overlapping back faces where the artifacting is happening.
Also why not project that within ZBrush?

if you do an exploded bake that could fix it

separate the pieces placing them further a part from each other and then bake them

Oh makes sense, here I have been searching the net for a special technique to 'explode bake'
I would think the polygons on the Hi poly need to stay in the same place in order to bake to where the lox polys uv's are, correct?
and disturbing them would alter the bake and mess it up.

hehe sorry should of explained

lol its just so that certain pieces usually ones really close to eachother don't end up baking their info onto other pieces by mistake

This is a great tutorial on normal map baking. It goes over how to do an exploded bake.
Its for 3ds max but the exploded bake process should be similar in other 3d software.

A real difference by seperating both the low poly objects and hi poly objects, still some artifacts though.
