Turbosmooth OK on Tyflow, not OK on TyCache

[Elwood89]

It turned out like this:
1. To render any modifiers on top of the TyCache on my workstation it was enough to turn off tyCache/Display/Acceleration/Use GPU instancing.
2. However to render with modifiers over the network using backburner I also had to switch tyCache/Render/Vray Instances => Meshes.
I'm on Vray 3.7.
Is that intended?
