I could change interactively volume mask voxel values set by:<br clear="none">

<br clear="none">
Now when i switched to VTK 7.1RC & OpenGL2 I can't make any modifications to<br clear="none">
volume mask interactively. Calling Update(), Modified() on every element of<br clear="none">
the pipeline (volume, input data, mask input, mapper) does not affect visual<br clear="none">
result.<br clear="none">
<br clear="none">
The only way I can get the updated mask volume is to call:<br clear="none">
<br clear="none">
Renderer->RemoveVolume(Volume) ;<br clear="none">
Renderer->AddVolume(Volume);<br clear="none">

Is there any way that I could force volume mask update for<br clear="none">
