I've got a good feel for creating a material in eevee that bends light around the black center of a mesh, but in the simulation the black portion warps when it is affected by the other black hole rotating around it.
I'm not sure if I should try to emulate this warping with deforming the mesh with something like an empty and a modifier or if it would be possible to do it with something procedural in the shader editor. If it could be done in the shader editor it would be incredible, but like anything in blender there are always multiple ways to do it. Any suggestions?
