Question by daimadoushi · Apr 15, 2013 at 02:29 AM · normal mapinvertseam

Normal map, object doesnt connect well

Hi, After a entire day digging the internet unsuccesfully, I decided to submit my issue.

So I'm trying to use modular assets in unity and I'm stuck with a wierd shadow/normal map behavior. As it's better an illustration then a long speach, here's some :

Here : Simple diffuse map with specular, everything's ok : alt text

Here : Same thing with my normal map, there's a seam: alt text

Although my 2 tiles are a bit different, I use the same material (so same texture, same normal map). The problem is at the seam, as I drag the light around, the two tiles act as if the light was'nt lighting them from the same side, if you know what I mean.

Look at the middle red circle, look at the big stone on the right, there's shadow on the side of it, as the light is on the right. But on the next tile (same stone), there's highlight as if the light was coming from the left.

Any idea of what would the problem be ?

I made a little unity package with the test scene, if you got some time :)

Thanks for any help.

Here's the file, it's named error.unitypackage : https://docs.google.com/file/d/0B871ZvKB4AC1MDdpejZwM19Nb2c/edit?usp=sharing

Hi there, I come to tell that I fixed the problem.

The problem was that, for one mesh, the Uv was rotated by 90° so the normal map was reacting as described. Rotating the Uv's of the concerned meshes seems to do the trick, although I still need to pay attention on wich side I connect my meshes (which is a bit annoying, but I dont know if their could be a solution for that)
