Is the option "Eable Vray Interface" of TyCache objects necessary?

[annlee]

Hi guy~
I want to know if I  disable the option " Enable Vray Interface" in the 
tycache will cause any problem?

Because I turn on the "Enable Vray Interface" that will let my vray can't  rendering tycache, I must turn it off.
But I fear that will cause other problem.
Thank you for your replay.

The effect of the checkbox depends on the situation. If you disable it, certain versions of VRay (3.x/4.x) will not be able to render the particles as instances.
