Title: Railclone with animated spline as clipping area renders incorrectly on slaves
Post by: Ruud3DV on September 16, 2016, 07:56:12 PM

I've got a spline used as a clipping area for an Array 2S Railclone object (flooring). The entire spline is moved in frame 1. It renders fine for frame 0.
When rendering frame 1 on the workstation alone, it renders fine. But when rendering frame 1 on a slave the position of the clipping area isn't updated in frame 1.

Can this be fixed or is there a workaround? I can't use DR or a renderfarm with this problem.

Hi,

Thanks for reporting this problem. I can confirm, that while using animated Clipping Splines, the RC object might not be updating correctly (even locally). Our main developers will look at such issue in depth to check what can be done to avoid this kind of troubles. Once again, big thanks for your feedback, hopefully it's something that can be fixed soon.

Best regards,

Hi, i'm checking this issue.

Due to the way that RailClone uses Base Objects, we cannot fix this limitation without causing undesired side effects. But there is a simple workaround:

- Create a Dummy object.
- Apply a Linked XForm modifier to the spline, and assign the dummy as Control Object.
- Move and animate the dummy.

The idea is to deform the geometry of the spline (which is done by the modifier). This is recognized by a RailClone as a change in the spline, instead any modification of Position/Rotation/Scale is ignored.

I hope that helps.

Thanks a lot for the workaround! Works like a charm!
