Thanks to Zax, problem solved.
Problem was I Used HighQ OpenGL renderer (which worked fine for one instance of my 3D object – but not for appearance at the end of my timeline). The reason I fiddled around with HQoGL in the first place was a seriously pixellated shadow. The culprit turned out the be a crazy light I used for effect on media prior the 3D entrance. with 110% strength & 100% shadow casting that was very close to my object – which overdrew the default 500×500 shadow buffer. I’m back on InvigRenderer and just Re-did that scene’s lights with more modest ones.
All schweet now.
It’s great when guys create great products with great client service to back it up!
Thanks, Zax!
