Vray Distance Tex + Link Issue = <deleted>

[Dmerc]

1. We have an object linked to a plane (Water). When trying to use this object as a distance object for the distancetex (Bumpmap on watershader) on the waterplane it becomes instantely <deleted>.

Unlinking solves the issue, but of course is undesirable for the animation.

2. Can Vray Distance Tex be used as Bump? It does not seem to have any effect ...

Best regards, Peter
