My problem is that my low poly model has a really crappy relationship with the smooth shader, and none of them want to make the first step to settle things.
When i bake, i get a normal that desperately try to fix the shading issue but don’t really succeed, i tried edge split and sharp edges, which fix the thing, but automaticly i get artefacts on the edges when the normal try to smooth them, which is normal.
I tried to retopo my low poly mesh in a lot of configurations and it just made the polygonals artefacts different.
When, by despair, i added an edge loop on the strong angles, it only reduced the problem, which makes me believe that my problem is at the base of the process.
A forgotten setting ?
On the image, the original low poly mesh is on the left and the retopo with additionals edges loops is on the right.
The original has +/- 300 tris and the retopo +/- 400, which is not that bad for something that simple shaped…
Thanks for the help.
