Organic tessellation

Maximum-Dev

Hi,

I started to tessellate some organic objects for the first time (really..) and well not quite what I've been expecting.



Been trying all the settings in UE4 as well but didn't get anything acceptable. I could use some guidance.
How can tessellation work so well on stuff like this but look so weird and break the mesh on my end?

Are you using hard edges on your model? This can cause breaks when you use tesselation.

The whole rock mesh is in 1 smoothing group.

In Unreal, there is a checkbox called "crack free displacement". Its under the tessellation settings in the material properties.
