Troubleshooting

The Place button is greyed out​

Step 1 tells you what's missing:

  • Pick a prefab or model first: drag a model from the Project window into Prefab or model.
  • Pick the object to put it on, or switch to In the world: you chose On an object but didn't drag an object into Object.

I can't see the new object​

New objects start at the centre of their space: the centre of the world, which may be far from your room, or the centre of the object they sit on, which may hide them. Press Find next to the object, then move it in step 2 Position.

Learners can't pick the object up​

  • Pick it up and carry it isn't ticked. Tick it in step 3 Interaction.
  • The model has nothing to touch. If the tool warns that it can't measure the model, it has no shape to grab. Ask whoever prepared the model to add a collider.
  • The model already has its own grab setup on one of its parts. The tool then adds nothing and shows a warning, so the model's own setup is used.

Some options are greyed out​

Resize it with both hands, Can be thrown and Falls and collides only work for objects that can be picked up. Tick Pick it up and carry it first.

A thrown object flies away and never lands​

Tick Falls and collides too, so it falls to the ground.

I unticked an option, but learners can still do it​

Unticking doesn't remove abilities a model already has, or that were added before. See Choose what learners can do with an object.

Steps 2 and 3 are greyed out​

No object is selected. Click one in the list, or place one first.

My changes disappeared​

Either the scene wasn't saved, or the changes were made in Play mode. Stop Play mode, make the changes again, and press Save the scene in step 4 Save.
