Early transfer test on a file I am building in Vectorworks then moved into Cinema. Still building, but just wanted to see it quickly. When I render with the VFB, I get expected results, but when I render with the IR, I get huge geometry shifts. Yes - the way Vectorworks handles symbols/instances is annoying :) But I do this all day long and have never seen this, so I don't know what's different in this file. I'll upload the C4D file.
Windows 10(1709 Build 16299.431) Running Cinema 4D R18(RB197636) and using Corona B1(core 1.7).
Thanks for taking a look!
EDIT: I also just noticed the file size is humongo! Not sure why it is so big... (450MB). 1526056337_Stairs-EA.c4d.zip
