Edges of low poly mesh affecting normal mapped model
null
Basically i am using substance painter 2 to bake out my normal maps. When i bake the normal maps there are obvious lines appearing all over the model along the edges of the low poly mesh. I have no idea why it is doing this but wouldn't be surprised if i am doing something wrong or it is a problem with the meshes.
Around the eye and in other areas where the mesh changes a lot the lines are far more visible but even in lesser detailed areas they are still slightly visible. This is giving me horrible looking models when i apply these normal maps to the model outside of substance to use for games and such.
If anyone can give me any tips i would massively appreciate it.

- Make sure that no edges are marked as sharp (Edit mode > Mesh > Edges > Clear sharp)
- In Object mode, set the shading to Smooth on the left panel
- In the eighth tab of object properties (data tab, little triangle icon), enable Auto Smooth and set it to 180.
- If things don't seem to react to your input, that might mean that you somehow ended up with custom normals. To clear them out, in the same tab where Auto Smooth is located, click "Clear Custom Split Normals Data" under the Geometry Data rollout.
