In Twinmotion, user objects keep coming apart because you can’t select the whole object with a click - You have to select it through the Browser. When you select your user objects to move, they break apart because you can only select the sub groups with the pointer (move tool) selector.
The only work around I can find is to completely explode your model before installing it into Twinmotion. But this has it’s obvious disadvantages.
There needs to be a better way of grouping instances - so they work like the preset library.
Also, a way to locate the gizmo axis in a sensible location would be useful too.
