TyFlow actors disappearing when using RS instances

[nicoknudsen]

Don't disable the interface, disable the Mesh operator. That's what's triggering them to render.

Ok! That did the trick!! big thanks!!

One more thing on this:
When i render out tyflow actors using "Enable Particle Interface" they render without smoothing.
Despite adding TySmooth on top of the icon, or adding a smooth operator in the flow. 
Turning off "Enable Particle Interface" then Tysmooth works and the actors are smooth.
-But then ill have do build a big tree of materials since Tyactor doesnt seem to render with the materials from the Tyactor anymore, despite checking "Instance material". 
With "Enable Particle Interface" on the materials get rendered correctly but without smoothing.
Make sense? anyone with a sollution?
