BlenderBIM 4D Scheduling - Removal tasks not removing from viewport?

   Hi,

   I really enjoy the 4D BIM capabilities of BlenderBIM, but I am wondering about the tasks assigned a "PredefinedType" representing any destructive task (REMOVAL/DISMANTLE/DEMOLITION etc).

   When I am assigning objects to this task, they turn blue for the duration of that task, and then they are completely visible (and the usual grey color) from there on out. I am not able to make any objects "invisible" in the viewport using the tasks. Does anyone know how to make objects disappear, maybe there is a button/choice I havent found yet?

   I am including an image with green and blue colors simply to illustrate (somewhat) what I am trying to describe..

   PS: If it isnt clear, I want objects assigned "removed" types of tasks to stay removed...

   Hey there

   Maybe this ifc sample file with IfcTask with PredefinedType CONSTRUCTION, DEMOLITION and MOVE https://github.com/Martin15135215/git_ifc_test/blob/main/test_two_cube_wall_4d.ifc can help you out.

   The thread to that ifc file is: https://community.osarch.org/discussion/1131/

   Thank you, you (and Moult) summed it up perfectly in that thread:D

   In my ignorance, I had simply assigned my objects as "output" to all tasks, no matter the type. They should have been "input" to the destructive tasks...
