My computers are:
Main computer - network licence, used as main computer
Second computer - network licence, used as DR machine
Third computer - only node licence, used as DR machine
Thanks for a tip.
So, I have did basic scene: plane and teapot that is scattered by forest pack over the plane. When I render this scene, all DR machines work great and render the FP geometry.
Then I have replaced the teapot by standard forest pack grass from library. Bud this time, all DR machines render NO FP geometry. All DR nodes loaded scene and did render in second because they rendered just the plane surface.
When I open the same scene on the Second computer, scene opens, load FP grass in the viewport, I can edit it because network licecence. If I render this scene on Second computer, all works great, it render FP geometry.
When I open the same scene on the Third computer, scene opens, load FP grass in the viewport, I can't edit it because there is no network licecence, only node. If I render this scene on Third computer, nothing works, it render NO FP geometry.
Hmmm...I do not understand it.
