It seems the problem is more serious than I’ve thought.
It’s the WaveWorksStaticMeshComponent that is not usable with the example materials (both OceanMaterial and WaterPlanMaterial), something related to tessellation and waveworks functions invoked inside their shaders. The only usable comp is the WaveWorksComponent, which is giving me some headache for doing some basic stuff like resize and move the water plane like I was able to do with static mesh component. After a day of struggling I’m going back to the 4.19.
Any help is welcome!
Thanks in advance
edit: I’ve discovered how to move and customize also in way (just tweaking waveworks asset), hope to not find other issues!
