stuck in a uv normals seam hell hole

OnlySunny · Mar 2016

Hey everyone, Im really stuck, going round in circles. I've abandoned my model until I can get the workflow down on a simple box but i cant get the seams right. So i have a low poly cube made in Maya, taken into Zbrush, subdivided and some basic sculpting just for testing, then exported a low poly and a high poly out from Zbrush. Ive opened the low poly from Zbrush up in Maya re-UV, been reading up here and moved the faces apart in the UVs. Ive tried a different combination of Normals smoothing in Maya before importing the high and low in Xnormals, but whether I smooth all the normals in Maya, or smooth them then choose the cube edges and harden them as Ive read to do, whatever i try, I always get dodgy uv seams.
can anyone help please me with my workflow?

Try increasing the padding in xNormal and also make sure your low poly is set to use imported normals.

upping the edge padding has made it much much better, thank you!

Also, try manually straightening the uv island edges, may be the resolution and maya sometimes shows the straight edges jaggy (i guess its because of aliasing and approximating when zoomed out ) but in the uv layout on the right the edges of UV island dont look straight, try fixing them and see if it makes any difference.
