VRay Render Mask Not Working With TyFlow

[biglittlepictures]

It's be nice to be able to use VRays Render Mask to only render TyFlow objects in a layer.  Seems like all render mask types don't work with TyFlow yet.

It is a pain to create a manual switch to render things as separate layers, but will do for now.

Have you tried changing mesh operator to triangle, and unticking "render only"?
That way, you basically force Tyflow to be seen by Max just as any regular mesh
(if above doesn't work, in addition, try adding edit mesh modifier on Tyflow icon).

Beyond doing what d4rk3lf suggested, all rendering issues/suggestions need to be taken to the developers of the renderer.
