Tessellation help UE4

b_gibson

I've never used tessellation before and I'm currently having an issue with unreal where the tessellation , looks fine from a distance but close up becomes fragmented and ugly.  I don't really understand why this is happening. I'd like for the tessellation to still look good close up, like grains of snow for the sake of using this material in screenshots and close up. Any help is appreciated

What does the mesh look like? Did you make the material or did you get it from the store or the internet? What do the UV's look like?

The problem is ambient occlusion. Try disabling that if you want an easy solution. You could also try adding something to your material that flattens out the tessellation depending on distance, viewing angle, or both.

The real problem is the spiderweb kind of topology coming from the pure reliance on tessellation. This is a super wasteful method anyways... But if you would like to fix this, use some pre tessellation.

It's unavoidable on a landscape, right? That's where I've encountered it.
