I have ported VXGI 1 into 4.19 and it works as intended. I will port it to 4.20 by the end of weekend, but I believe many more changes were made in 4.21 regarding a few things, so I may not have the required skill for 4.21 VXGI 1.
I can upload 4.19 if anyone wants that, it has everything merged in GW with VXGI 1 instead. It’s a built local version though so like 15gb dl.
