Unity Modular Environment Seam Issue

I'm working on a modular environment set for my game and ran into a weird issue. I have straight walls and then a small curved section. When I added them into my scene I noticed that there are very visible seam marks between the straight and curved wall sections. Has anyone run into this problem before? How can I fix this and what is the issue?

Any help will be appreciated!

 

Make sure that the normals of the border vertices are the same, else you'll get lighting discontinuities like here.

 

How exactly would I be able to do that? I use Maya for example. Thanks!

 

There are many ways :
- have a unique mesh with soft edges that you split
- select the vertices and use the component editor to set the same values in the normals
- ...

In your case here, I'd combine all objects, merge the overlapping vertices with Merge With Threshold, soften edges, then split back...

 

So my only issue is that Im going with a modular design, so I need all the meshes to be unique or else it defeats the purpose of a modular design. I sadly do not have component editor because Im using Maya LT but I tried conforming all the normals and that didn't help. My scene currently looks like this

 

No no you don't need the meshes to be unique... you just need your normals to point towards the same directions on the borders of adjacent meshes... you still can use instances of course...

Here's for the component editor :

 

Sadly Maya LT does not include what you are showing. I did however set the normals all to 30 degrees but the problem still exists. I also tried disabling all but one light and if I move that light across the floor I don't see that issue of the seems. It seems to deal with the light potentially.

 

Solved the problem! So I was using real time lighting and my Pixel Light Count was set to 4 which is too low. I changed it to 10 and the light issue was gone. I didn't like this solution so I changed my Pixel Light Count back to 4 and instead started using Deferred Light Rendering which works very well. Thanks for your help!

 

Just a thought. If you're using Maya LT, you might be eligible for the latest student version which is complete (apparently LT isn't).

 

Sadly I'm not a student and I prefer the cheaper price of Maya LT since I will be able to sell what I create if I ever get that far.
