box collider

[JetsSimavDibris]

Hi there, I have an old project done with Sofa v20.12.02 and I'm improving it using Sofa v22.12.
Everything is ok, but I can see the box collider/box roi in the simulation, there's a way or a new command to hide them while running the simulation?

Thank you

Hey @JetsSimavDibris

Congrats for making the v20.12.02 ➡️ v22.12 migration! 👏

View options can be customized using the VisualStyle component, you can for instance try:

<VisualStyle displayFlags="showVisual hideBehaviorModels" />

Hope this helps

It does seem to come from here but rather from some python functions of yours like sphere(..) or Skin(...)
could you share them as well?

Hi @hugtalbot
you mean these?

    name=parentNode.addChild(name)
    name.addObject('MeshObjLoader', name='sphere', filename="C:\sofa\src\VirtualSkinV4\mesh\sphere.obj") 
    name.addObject('OglModel', name='sphereVis', src='@sphere', scale3d="1 1 1", translation=translation, color=color)
    if SphereModelNumber=="M1":
        sphere.M1=name.sphereVis
    if SphereModelNumber=="M2":
        sphere.M2=name.sphereVis
    if SphereModelNumber=="M3":
        sphere.M3=name.sphereVis

        sphere.M4=name.sphereVis

Hi @hugtalbot any news about it?

[hugtalbot]

the data drawBoxes='true' in the BoxROI draws this red boxes
Set it to false to remove them from the view

cheers

Thank you so much, it works!
