Little problem with the Bake

SuSo

Hi! i have a problem that i can't resolve.

When i try to bake my HP to LP, ALWAYS happen the same thing, in the right/left side, i have a few lines after the bake.
I have tried to change the format of the file, the sotfware of the bake, the UV, a little changes in the retopo... and always is the same mistake

I think the best option could be make it again but i would like to figure out how to solve it.

Thanks!! ^^

My best assumption is your LP has no hard edges, or not enough of them. Your normal map is doing too much heavy lifting trying to match the bad shading/smoothing of your low poly to your highpoly.

Place your hard edges at least at 90 degree angle changes, and split them in your uv's, you 'll get a much cleaner bake.

Okay, i gonna try it

Thanks Kanni!

Assuming the problem is the artefact on the flat side part you need to sort that ngon out. 

The mesh is being triangulated in an awkward way at bake time so if you explicitly define edges that won't happen.

That n-gon is just an oddly shaped quad, and there's artifacting everywhere else on the model which lead to just a smoothing on the low res. But I do agree, you should triangulate properly upon export and not let bakers/engines triangulate for you.

Yeah,  I should have qualified that.  What I suggested was meant as an addition to your suggestions  rather than an alternative.
