tiling more apparent in dark area UE4

spexel · Sep 2016

Ok so I'm trying to build a modular room, I have a piece of wall that is 100x200, in the images below you will see three of those piece side by side, the texture is supposed to tile but I still can clearly see a seam when it is in the shadow. When there is light the seams disappear, I don't know if it just because it get blown out but I can't figure out the problem. Thanks

When it's dark:

With light:

Thanks! I tried almost everything mentioned in there and even tho I get a better result, I still have some issues. Here's a couple of screenshots with production lighting:

Here's with the following setting:

Lightmap resolution: 512
static lighting level: 1.0
Num indirect lighting bounce: 6
Indirect lighting smooth: 0.6

And I also upped the lightmap resolution of the beam. Here's the result:

Any other idea? (I am trying with the static lighting level at 0.1 at the moment but the build takes forever)

Here's the result with the same setting with the exception of static lighting level. It is now at 0.1

Ok I went back to the basic and I applied a lambert to everything in my scene.

lightmap: 128
static level lighting: 0.1
: num indirect lighting bounce: 4
indirect lighting quality: 2.0
indirect lighting smooth: 0.6

Build: production

We don't see the seam as much but I don't understand why everything is so blocky and low res.
