I have made root grow VFX. It consist of two parts: hda to generate geometry and UE material to have animation effect. More details in the video.
A have also included project file because there is COP node for generating wood texture.
In UE project you simply open niagara and play with dynamic material parameter.
Basic workflow is follosing:
HDA generates "pipes" with following options: height, radius and number of roots.
After it you bake the mesh and put it in niagara under "mesh render" with material inside MAT folder.
Some tweaks could be made in parameters of material.
