Motion blur on Liquid Mesh, add object tag to input custom XYZ vertex

Add object tab to have option to input custom XYZ vertex for motion blur.

Hi TomG, I hope you are doing well. I have the same problem, looking like a mad man everywhere for a solution, I have a liquid simulation and I have seen online that other rendering engines have Object tag, where you can enable Motion blur and add XYZ extracted vertex map tags from the simulation... (from 1:35)

(also similar Octane has object tag with XYZ inputs)

I understand that maybe at the moment corona don’t have this custom tag that can take XYZ, but is there a way/workaround that we can tell Corona to take XYZ vertex map and use to calculate the motion blur from them? I think this will benefit a lot of artists out there. Kind Regards, Cory
