I have a Blender 2.8 scene with animated true displacement. It is created using material nodes and works fine in Cycles. However, EEVEE doesn't displace my meshes truly, only normals are changed. Is it possible and how to solve the problem now or in the future?
It seems that EEVEE doesn't support true displacement in the nodes and we don't know when it will. However, it is not so difficult to find another solution.
To replace animating math and displacement nodes, I used several Displace modifiers with different textures and empty objects which have keyframes on their LocRotScale. This approach is explained in detail here. I'd like also to highlight that in my case the
Direction value was very important – displacement looked ugly before I limited it to Z axis only.
You would have to bake the textures and use a displacement modifier as of right now, unfortunately. It will probably support true displacement in the future though.
