Some help with normals?

Hi, I recently started modelling and began a simple project to learn trough.
I made a mess by makink a high poly, then figured I would need a low poly wich I lost in the way through lovely Dynameshes.
Finished my low poly, made a lame UV to check if it worked a little at least.
Did, so I refined the UVs, went back to baking normals and got this:



Why is this "thing" happening? This contrast, how do I handle it?
Thanks!

It looks like you're baking object space normals, which is probably not what your engine is using. In xNormal go to the Normal Map options where you select what bakes you want. There will be a box with ellipses to the right, click that and check mark 'Tangent Space' and rebake.

HOLY COW! I feel like god or something, thanks a lot, the other issues on the map I will attend now, thanks again!

If I can give you this advice, never do temp/fast/"lame" (as you called them) UVs, because sometimes you can get errors which (at first) you might not understand from where they are coming from, but at the end you might discover that it was something related to the UVs. Doing proper UVs from the beginning it's just a time saver.

However, from the pics I see bad smoothing groups, missed calculations (meaning hipoly and lowpoly were not close enough and/or you didn't use a cage\envelope properly) and a seam (from the bad uvs\smooth groups).

I suggest you to study this http://wiki.polycount.com/NormalMap it will save you a lot of time in the future.

Thanks I improved this last night, It still needs some work but it's on the right way!

Good to hear.
