Getting a crack between materials that are seamless.
This problem does not exist when just repeating the same seamless square material, or when photoshopping 2 different materials into 1, but does when trying to put 2 different materials that share a seamless edge. It cracks along that edge.
Here’s the material / tessellation info:
All I did was take 4 square seamless textures and photoshop them together to create 1 long column. I applied the same editing to all maps (normal, displacement, etc.)
Then I just cut it up into 2 textures, top and bottom. (That’s where the problem is. As you can see where the crack is.)
There must be something wrong with how I am doing materials / tessellation in UE4?
The surface is just a completely uniform plane:
