Maybe in the first try with the different smoothing groups, your uvs are not cutted in the same edge as your SG, can you add a screenshot of your uvs? maybe that can help

EspiSensei

may could be that, i'll try to change the Uvs.

Attach the actual Uv's:



Thank you for your response, Ricky ^^

All hard edges require a UV seam but not all UV seams require a hard edge. That should help with some of your issues atleast

Avoid the extreme shading on your lowpoly, that'll only mean your normal map/bakes will have extreme gradients to compensate for the bad low-res smoothing. The smoothing set up your had in the very first image is almost quite there (seems to have some smoothing group breaks here and there nonsensically, like an autosmooth that was a bit too tight on its threshold)

Ok guys, i'll review de smoothing groups and de UVs.

Thank you so much! ^^
