Adding a second volume seems to duplicate the first one

[frauzufall]

Starting the VolumeRenderDemo and adding a new volume (using the T1 head) adds a blurry (?!) version of the first volume and slows down my machine drastically.

Not sure if it is a second volume. But there is defnitly something wrong with visibilty. I can only hide all or none of the volumes by setting all volumes to visible. As long as one volume is set to visibible all volumes are visible.

@moreApi that sounds different, this bug is:

Run mesh demo: see the cube volume
Add T1 head: another cube is added to the scene and there is no head.

[moreApi]

Then I cant repoduce the bug. For me the head is added but it is hidden by a very small scale and transparent transfer function. But that is expected behavior in my experience.

[moreApi]

I added the head by opening the sample in imageJ and then using "add->volume" in sciview

@moreApi you are very correct. I now understand why the visibility part is the main issue here.

If you delete the cube volume, then you can see the T1 head without doing anything with visibility.

should be solved by scenerygraphics/scenery#544 once merged
