FumeFX to VrayVolumeGrid miniscript

Fumefx 2 VrayVolumeGrid -FFX2VrayVG miniscript v0.1 -- 8/9/2019
Created by David Aviles. [email protected] .

FFX2VrayVG is a small script that creates vrayvolumegrid/s from two or
more selected and already simmed FumeFX grids.
It will align the created VrayVolumeGrids to the FumeFx ones and rename
them accordingly as well as loading the cache files from the master FumeFx grids.

It was inspired by Fumefx VZim v1.4 script -- 8/5/2019 .

Thanks for this tool Ronnen and team!
but none of your code is here, just an inspirational variable and this help
layout.

In my workflow i do prefer to first simulate multiple FumeFX grids via
Deadline and then, and once the cache files are ready, do the align, rename
and repath work.
So this tool is perfect if you want to render your already simmed and
compatible VDB FumeFX cache in V-ray.

Instructions:
- Select all the already simmed FumeFX grids
- Run the script
- Yes, I know! there's no ui, no macro, no button, no nothing, just a crude raw script to run. Hope it changes in the next iteration.
- Feel free to share this script and alter as needed.
